Autoranging MegaPACTM
AC-DC Switcher
USER GUIDE | UG:106
June 2013
Overview
The Autoranging MegaPAC AC-DC switcher allows users to instantly configure high
eciency, o-line power supplies that operate on either 115 or 230 Vac (47-500 Hz), or
260-380 Vdc. The Autoranging MegaPAC provides up to 1,600 W of output power with a
power density of 6.6 W per cubic inch. The chassis has 8 slots and can provide up to 16
isolated outputs. Its dimensions are 3.4"H x 6.0"W x 11.9"L (86,4 x 152,4 x 302,3).
A complete power supply is configured at the factory by selecting and inserting up to
eight same length slide-in output assemblies called ConverterPACs. ConverterPACs
incorporate one or two VI-200/VI-J00 and/or Maxi Vicor DC to DC converters and are
available in a wide array of output voltage and power levels. The net result is a power
supply that oers the advantages of a custom supply, but is assembled from standard
and modular building blocks. For detailed information about ConverterPACs, refer
to the ConverterPAC information sheets. Currently, the ConverterPACs used in the
Autoranging MegaPAC only use VI-200/VI-J00 Vicor DC to DC converters.
Refer to page 6 for a brief overview of the ConverterPACs used.
Manufactured at Westcor, a division of Vicor, the entire family of MegaPAC power
supplies is completely user-configurable. If output requirements change, i.e., more
power or a dierent output voltage is needed, upgrading is easy: simply unlock a
single screw and replace the slide-in ConverterPAC assembly with a same length
ConverterPAC and one that has the desired voltage power rating. For additional
flexibility, ConverterPACs can be connected in parallel to increase output power
(booster ConverterPACs), or in series for higher voltages (total output voltage should
not exceed 400 V). The driver is to the le of the boosters when looking at the output
end of the supply. A user-friendly interface provides control and output sequencing
capability, in addition to useful status indicators. Please consult our Applications
Engineering Department if you have other special requirements.

Mechanical Considerations
The Autoranging MegaPAC can be mounted on any of four surfaces using standard
8-32 or 4mm screws. The chassis comes with four mounting points on each surface;
maximum allowable torque is 20 lb-in. The maximum penetration is 0.15 in. (3,8mm).
When selecting a mounting location and orientation, the unit should be positioned so
air flow is not restricted. Maintain a 2 inch (5,1cm) minimum clearance at both ends of
the Autoranging MegaPAC and route all cables so airflow is not obstructed. The standard
unit draws air in at the fan side and exhausts air out the load side. If airflow ducting is
used, avoid sharp turns that could create back pressure.
The fan moves approximately 30 CFM of air.
Avoid excessive bending of output power cables aer they are connected to the
Autoranging MegaPAC. For high-current outputs, use cable ties to support heavy
cables, minimizing mechanical stress on output studs. Be careful not to short-out to
neighboring output studs. The Autoranging MegaPAC is supplied with serrated, flanged
hex-nuts on all output studs. Therefore, thread locking compounds or lock washers are
not required. The maximum torque recommended on flanged nuts is 45 lb-in. Never
loosen the inner nut on a ConverterPAC. This nut supports the hardware inside the
ConverterPAC and is factory torqued. Avoid applications in which the unit is exposed to
excessive shock or vibration levels. In such applications, a shock absorption mounting
design is required.

MegaPAC Do’s and Don’ts
nFor units without Autosense, do not leave ConverterPAC Sense lines open. Always
terminate them to their respective output locally or at the load. If ConverterPAC
has Autosense, no local sense connection is required. See page 11 and page 14 for
more information on Autosense.
nIf needed, use Connector Kit # 19-130040 for the Autoranging MegaPAC.
nAlways fill all output slots of the MegaPAC. If a slot is not filled with a
ConverterPAC, it should be filled with an airblock. Airblocks are plastic assemblies
whose main function is to fill up an empty slot. Any airflow escape from an empty
slot significantly degrades thermal performance, and can result in overheating and
damage to the power supply.
nDo not unplug ConverterPACs while input power is applied.
They are not designed for hot-plug applications.
nDo not restrict airflow to the unit. The cooling fan draws air into the unit and forces it
out at the output power terminals.
nFor power expansion use booster ConverterPACs. Viewing the unit from the output
terminal side, always insert boosters to the right side of the driver.
nDo not use boosters as independent outputs.
Disconnecting bus bars will damage booster ConverterPACs.
nFor booster arrays, do not remove busbars.
nAlways ensure that output hex-nuts are properly torqued before applying
power to supply.
nRun the output (+/–) power cables next to each other to minimize inductance.
nWait 5 minutes aer shutting o power before inserting or removing ConverterPACs.
nDo not attempt to repair or modify the power supply in any manner other than
the exchange of ConverterPACs as described in this Design Guide.
There are no user serviceable components.
nInsert proper fault protection at power supply input terminals (i.e., a fuse).
nUse proper size wires to avoid overheating and excessive voltage drop.
nNever loosen the inner nut on a ConverterPAC.
nVerify output nuts are tight before powering up.
Technical Description
The Autoranging MegaPAC chassis consists of an o-line single phase AC front end, EMI
filter, cooling fan, customer interface and associated housekeeping circuits. Input AC
mains voltage (L1, L2/N and GND) is applied to a terminal block. The input current is
passed through an EMI filter designed to meet conducted noise limit "A" specifications
of EN55022, Level A. At start-up, inrush current is limited by an NTC thermistor prior
to being passed to the power rectifiers. The thermistor is shunted out shortly aer
initial power-up using a DC bus voltage Sense circuit and a relay. The sense circuit also
controls the input autoranging selection relay. The power rectifiers and filter capacitors
are arranged in a conventional full wave bridge rectifier/voltage doubler configuration.
This operates as a full wave bridge rectifier on 230 Vac, and voltage doubler on 115 Vac,
delivering unregulated 300 Vdc to a high voltage backplane. The backplane supplies
power to a variety of ConverterPAC assemblies that provide the desired low voltage,
regulated outputs.

UG:106 vicorpower.com Applications Engineering: 800 927.9474 Page 4
Voltage conversion in the output assemblies is achieved by Vicor's family of
Zero-Current-Switching (ZCS) DC-DC converters. These are forward converters in which
the main switching element switches at zero current. This patented topology has a
number of unique attributes: low switching losses; high frequency operation resulting
in reduced size for magnetics and capacitors; excellent line and load regulation; wide
adjustment range for output; low EMI/RFI emission and high eciencies.
At initial power-up, the Autoranging MegaPAC outputs are disabled to limit the inrush
current, reduce peak currents in the autoranging relay contacts, and allow the DC bus
potential to settle out to the correct operating level. A low-power flyback converter
operating with PWM current-mode control converts the high voltage DC bus into
regulated low voltage to power the internal housekeeping circuits and DC cooling
fan. When operating on 115 Vac, the internal housekeeping Vcc comes up within 1s
aer the application of input power. On 230 Vac, it comes up within 500 ms. The input
range selection circuit may take up to 200 ms to select the range if 115 Vac is applied.
When 230 Vac is applied, the circuit immediately selects for operation on 230 Vac.
Once the input range selection has taken place, the AC Power OK signal asserts to a
TTL "1" indicating that the input power is OK, and allows the power outputs to come up
typically within 15-30 ms later. An auxiliary Vcc output of 5 Vdc sourcing up to 0.3 A is
provided for peripheral use.
An output Enable/Disable function is provided by using an optocoupler to control
the Gate In pins of the ConverterPAC assemblies. If the Enable/Disable control pin is
pulled low, the optocoupler turns on, pulling the Gate In pin low and disabling the
ConverterPAC output. The typical delay associated for an output to come up when
measured from release of the Enable/Disable pin is 5-10 ms. The General Shutdown
function controls all outputs simultaneously and works in a similar manner.
The ride-through (holdup) time is the amount of time the load can be supported before
loss of output regulation aer the loss of input power. Detecting the loss of input power
takes a finite time period, aer which the AC Power OK signal goes from a TTL“1”to “0.”
This signal is available for use within 1.2 seconds aer initial power-up and can be used
to indicate an impending loss of power. A minimum of 3 ms warning time is given.
Following the loss of input power, the outputs are disabled aer the bus voltage drops
below its operating limit.

Configuring and Reconfiguring MegaPACs
Most ConverterPACs of the same length can be easily added, replaced, or moved by
sliding the assemblies in or out of a MegaPAC chassis. They are driver ConverterPACs
and can be inserted into any available slot. (Currently, the exceptions are the FinPACs
which can only be used in the PFC MegaPAC-High Power and the UniPACs which
can only be used in the 4 kW MegaPAC.) For outputs greater than 200 Watts, a
driver ConverterPAC and one or more booster ConverterPACs will be used. Arrays of
drivers and boosters should be configured so all boosters are placed in the slots to the
immediate right of the driver when looking at the output end of the MegaPAC.
Prior to removing or installing ConverterPACs, you must remove power from the
MegaPAC and wait 5 minutes. Failure to do so can result in personal injury or
damage to the supply.
Take standard ESD precautions when handling ConverterPACs.
Removing ConverterPACs
ConverterPACs can be removed by loosening the captive screw at the base. Once
this screw has been loosened, the ConverterPAC will slide out of the chassis. Once a
ConverterPAC has been removed, the empty slot MUST be filled with either another
ConverterPAC or an airblock. If the slot is le empty, it will provide an airflow escape
and can cause failure to the power supply.
Installing ConverterPACs as Drivers
ConverterPACs can be installed in empty slots by simply sliding in the new
ConverterPAC and securing the screw at the base. Power and interface connections can
be made aer the ConverterPAC has been installed.
Installing Booster ConverterPACs to Increase Output Power
ConverterPACs can be paralleled for more power. Additional power to an output is
obtained by connecting one or more boosters in parallel with a single driver. The
driver can be placed in any open slot. All boosters should be inserted in the slots to
the immediate right of the driver as viewed from the output end of the MegaPAC.
Figure 2 shows a driver placed in slots # 1 and 3 boosters placed in slots # 2 to 4. Aer
inserting the driver and boosters, they are paralleled using bus bars across the positive
and negative output studs. Drivers should not be paralleled with each other. Bus bars
between a Driver and Booster(s) should never be disconnected. For help in identifying
boosters and drivers, refer to the Part Numbering section on page 8. Please note that
total output voltage should not exceed the converter baseplate-output isolation rating of
400 V. For detailed guideline on how outputs should be placed in series, please refer to
the Applications note available on the website at www.vicorpower.com.

ConverterPAC Functional Description
ConverterPACs are the family of slide-in output assemblies used in MegaPAC power
supplies. Most ConverterPACs of the same length are interchangeable within a
MegaPAC and between dierent AC input MegaPAC chassis. They can be added, moved,
or changed as necessary. The following ConverterPACs can be used in the
Autoranging MegaPAC.
ModuPAC
The ModuPAC output assembly consists of a VI-200 DC to DC converter that converts
the high voltage bus to the desired regulated output voltage. Each ModuPAC can provide
up to 200 Watts of power. Multiple ModuPACs can be paralleled in a driver-booster
configuration to provide more power. ModuPACs are fused with a PC-Tron, DC-rated,
fast-acting fuse. A passive LC filter is used to reduce output ripple/noise down to 1%
typical, and 2% maximum peak-to-peak from 10% to 100% of rated load. An optional
DC Power Good signal, or output voltage Trim potentiometer can be specified. The
ModuPAC contains overvoltage protection (OVP), overcurrent protection (OCP), and
overtemperature limiting (OTL). The OCP has automatic recovery when the overcurrent
condition is removed. The OVP and OTL are latching functions and require recycling of
the AC input power to restart.
JuniorPAC
The JuniorPAC consists of a VI-J00 DC to DC converter that converts the high voltage
bus to the desired regulated output voltage. JuniorPACs can provide up to 100 Watts of
output power and are fused with a single PC-Tron, DC-rated, fast-acting fuse. A passive
LC filter is used to reduce output ripple/noise down to 1% typical, and 2% maximum
peak-to-peak from 10% to 100% of rated load. An optional DC Power Good signal or
output voltage Trim potentiometer can be specified. The JuniorPAC contains output
overcurrent protection, which recovers automatically when the overcurrent condition is
removed. Overvoltage protection and overtemperature limiting are not available.
DualPAC
This output assembly consists of two VI-J00 DC to DC converters that convert the high
voltage bus to the desired regulated output voltages as noted above.
RAMPAC
This output assembly consists of a VI-J00 DC to DC converter with a Ripple Attenuator
Module (RAM) and is designed for applications requiring low output ripple/noise.
The RAMPAC can attenuate the ripple/noise down to 10 mV peak-to-peak (or 0.15%
whichever is greater) over a 20 MHz bandwidth from 10% to 100% of rated load of the
converter.
BatPAC
The BatPAC output assembly consists of a VI-200 BatMod current source that converts
the high voltage bus to the desired regulated output voltage. The converter is fused with
a PC-Tron, DC-rated, fast-acting fuse. The BatPAC is a 200 Watts programmable current
source that can be configured as a battery charger. Maximum current and voltage
settings are controlled using potentiometers that come as a standard feature, or through
Trim pin access as an option. BatPACs are available for 12V, 24V and 48V battery
systems.

The FlexPAC output assembly consists of from 2 to 4 discrete outputs that convert the
high voltage bus to the desired output voltage. Each FlexPAC output can be manually
trimmed from 2 V to 25 V and supports up to 5 amps with a maximum output power
of 50 W per output. All outputs maintain less than 50 mV noise over the entire output
range. All outputs support local sense only. For electrical trim options and specific

Sense Connections
Note: Newer power supplies have a new feature called Autosense. If Remote Sense
connections are not made or needed, no Local Sense selection is necessary - simply
hook up the output and the unit will automatically operate in Local Sense. If remote
sense connections are made, the unit will operate in a Remote Sense mode. Remote
Sense terminals should be terminated to their respective output i.e - RS to - Output and
+ RS to + Output. See page 14 for more information on Autosense. For units without
Autosense, sense connections must ALWAYS be made. Not connecting Sense lines to

Interface Connections
Chassis Input Power Terminals (J9)
Input AC power is applied to terminal block J9 using a pressure screw terminal that
accepts a maximum wire size of 10 AWG. The maximum torque recommended is 10
lb-in. The connector manufacturer recommends the wires not be tinned. A ferrule
(Phoenix P/N 32-00-58-0, purchased from other sources) can be used to prevent fraying.
J9-1 (GND) is Earth Ground for safety; J9-2 (L2) is the Hot connection; J9-3 (L1/N) is the
other Hot or input Neutral connection.
A fault clearing device, such as a fuse or circuit breaker at the power supply input is
required per safety agency conditions of acceptability. It should be sized to handle the
start-up inrush current.
Output Power Connections (+P, -P for Single Output, or J1A/J1B for Dual Outputs)
For single output ConverterPACs, these terminals are two 1/4-20 plated steel studs. The
upper stud is positive with respect to the lower stud. For dual output ConverterPACs,
there is a 6-pin Molex connector for each output. J1A pins 1 and 4 are the +Output,
and J1A pins 2 and 5 are the -Output. Pins 3 and 6 are duplicates of the Remote Sense
terminals present on J1B. Use appropriate wire size rated to handle the full output
current, including short circuit levels. Avoid large current loops in output cables; run
power and return cables next to one another to minimize inductive eects. All outputs
are isolated and can provide positive or negative outputs.
Output +/-Sense Connections -J2 for Single Output, or J1A/J1B for Dual Outputs (See
page 9 for additional information on Autosense)
Newer power supplies may have some outputs configured with the Autosense feature
that automatically locally senses the output if remote sense is not used. To check if an
output has the Autosense feature, measure the impedance from the + out to + Sense and
- out to - Sense pins. If the impedance is 5 ohms, then the output has Autosense and
does not require local sense jumpers.
For units without Autosense, sense connections must be made. When making sense
connections, keep in mind that although all outputs are open-Sense protected,
the +/-Sense terminals MUST be connected to their respective outputs before the
Autoranging MegaPAC is powered up. Regardless of the output polarity configured, the
+Sense should always connect to the +Power output. The -Sense connects to the -Power
output. Sense connections are not required on booster ConverterPACs or if the Local
Sense option is specified. (Local Sense mode means that the Remote Sense lines are not
connected.) Sense pins can be accessed on J1A/J1B or J2A/J2B on dual output units.

Signal Ground (J10-10)
Signal Ground (see Figure 4 and Connector Pin Identification on Page 12) is an
isolated ground used as a reference for all J10 interfacing signals, and can be used for
ConverterPAC output status signals such as Power Good. This is not the same as Earth
Ground on input power connector J9.
Enable/Disable (J10-1 to J10-8)
The Enable/Disable control pins allow ConverterPAC outputs to be sequenced either
on or o. J10-1 through J10-8 are the control pins for output positions 1 through
8, respectively (see Figure 5 and Connector Pin Identification on Page 12). For
DualPACs and FlexPACs, all outputs are sequenced. In parallel arrays, only the driver
ConverterPAC need be controlled. The Enable/Disable pins should be pulled low to
less than 0.7 V with respect to Signal Ground to disable the outputs. They will sink 10
mA maximum. These pins should be open circuited or allowed to exceed 4.5 V when
enabled. Do not apply more than 6V to these inputs at any time. If driven from an
electromechanical switch or relay, a capacitor should be connected to eliminate the
eects of switch bounce.

AC OK / Power Fail (J10-11)
This is an active high TTL compatible signal and provides a status indication of the AC
input power (see Figure 6 and Connector Pin Identification on Page 12). It is capable
of sourcing 0.5 mA at >3.2 V and sink 16 mA at <0.5 V. This signal switches to a TTL “1”
when the high voltage bus exceeds low-line condition during turn-on, and switches to
a TTL “0” 3 ms (minimum) before loss of output regulation due to the loss of input AC
power. This signal can be used to warn external control circuits of an impending loss of
power.
Auxiliary Vcc +5V/0.3A (J10-9)
The Vcc on J10-9 is an auxiliary 5V regulated power source (see Figure 7 and Connector
Pin Identification on Page 12). It is +5 Vdc +/–5% with respect to Signal Ground and can
supply 300 mA maximum. It is short-circuit-proof, but if shorted all outputs will shut
down through the Enable/Disable circuitry. The Auxiliary Vcc typically powers user
circuitry or is used with the Power Good circuitry to provide a pull-up reference for the
outputs of the DC Power Good circuit on a ConverterPAC. If used for this purpose, the
Signal Ground on J10-10 must also be connected to the J3-1 Signal Ground pin of the
ConverterPAC.

Power Good (J3-3)
The optional Power Good signal on J3-3 is referenced to Signal Ground on J3-1, and
indicates the status of the output voltage (see Figure 8). This signal is asserted a TTL
“1” when the output voltage is above 95% of nominal. It is a TTL “0” when the output
voltage is below 85% of nominal.
If the Trim option is also used, the Power Good trip points DO NOT track with the
trimmed voltage. It is possible to trim the output below the fixed setpoints of the Power
Good circuit and cause a negative Power Good signal.
Power Good Inverted (J3-2)
This is the inverse of the Power Good signal and is referenced to Signal Ground on J3-1.
Signal Ground (J3-1)
Signal Ground on J3-1 is an isolated secondary ground reference for J3 status signals. It
is used to provide a reference point for the Power Good circuitry and is not the same as
Earth Ground on input power connector J9.
Vcc In (J3-4)
The Vcc In on J3-4 is an input that requires +5V either from the J10 Auxiliary Vcc, or
from another source. Input current to this pin is limited by an internal resistor to 3 mA.
If the J10 Auxiliary Vcc is connected to Vcc In on J3-4, then the J10 Signal Ground must
be connected to Signal Ground on J3-1.Earth Ground on input power connector J9.

+Sense/–Sense -J2-2 and J2-3 (See page 10 for information on Autosense)
The +Sense on J2-2 should be connected to the +Power Out, and the –Sense on J2-3 to
the –Power Out terminal. Do not reverse or leave the Sense pins open.Sense pins can
be terminated locally at the output of the power supply, in which case the power supply
will provide regulation at the output terminals. The voltage appearing at the load may
drop slightly due to voltage drop in the power cables. If it is necessary to compensate
for voltage drop along the output power cables, this termination should be made close
to the output load. Compensation of up to 0.5 V (0.25 V per lead) can be obtained. Use
twisted pair 22-24 AWG wire for this purpose.
For DualPACs, the +Sense pins are available on connectors designated as J2A-2 and
J2B-2 for outputs A and B, respectively. –Sense pins are on J2A-3 and J2B-3, respectively.
These pins are also duplicated on the power connectors J1A and J1B.
Reminder: Only units with Autosense will automatically operate in Local Sense mode if no sense
connections are made. It wil operate in remote sense mode if remote sense connections are made.
Units without Autosense MUST have sense connections (Local or Remote) terminated to their respective
output for the unit to operate properly.
External Trim (J2-1)
Output voltage can be trimmed using an optional factory-installed Trim potentiometer
or with the Trim pin. The Trim potentiometer is located on the ConverterPAC. If the Trim
potentiometer has not been ordered, the Trim pin must be used. When using the Trim
pin, the Trim limits are determined by the DC/DC converter used on the ConverterPAC.
Maximum Trim ranges are 10% above the nominal converter voltage and 50% below
the nominal converter voltage (except 10 V, 12 V and 15 V outputs which are 10% below
nominal) as measured from the output studs or output connector of the power supply
as measured from the output studs or output connector of the power supply.
Note: The combined effects of module trim up, remote sense and dynamic load step may cause the
module to trip OVP. (See page 6 for information on restart).
The Trim pin on J2 can be used to control the output voltage. It is referenced to the
-Sense pin on J2 and can be controlled by either a resistor network or an external
voltage source. To increase an output voltage above its nominal, it is necessary to
increase the voltage at the Trim pin above the internal reference voltage (Vref). The
reverse is true to decrease an output voltage.
Note: Converters are sometimes pretrimmed at the factory if a nonstandard output voltage is requested.
Standard voltages include 2 V, 3.3 V, 5 V, 10 V, 12 V, 15 V, 24 V, 28 V, and 48 V. If using a nonstandard
voltage, or if a ConverterPAC is ordered with a Trim option, the resistor calculations will differ from those
on page 19. Please consult the factory for assistance.

Example:
±10% Trim adjust on a 12 V nominal output.
Figure 10 shows a typical variable Trim circuit. Using a 10 k trimpot (R7), the resistor
values for R6 and R8 can be calculated as follows:
V1= Vref + 10% = 2.75 V Given: Vref = 2.5 V (see Table 1)
IR5 = (2.75 V - Vref)/RTH = (2.75 V - 2.5 V)/10 kW = 25 mA
Setting the bottom limit:
VR6 = 2.5 V - 10% = 2.25 V
And since IR5 = IR6 = 25 mA,
R6 = VR6/IR6= 2.25 V/25 mA = 90 kW
V2= V1+ VR6 = 2.75 V + 2.25 V = 5 V
IR7 = V2/R7 = 5 V/10 kW = 500 mA
IR8 = IR7 + IR6 = 525 mA
VR8 = (Vnom +10%) - V2= 13.2 V - 5 V = 8.2 V Given: Vnom = 12 V
R8 = VR8/IR8 = 8.2 V/525 mA = 15.62 kW
Using the above resistor combination, a 12 V output can be trimmed externally up
to 13.2 V and down to 10.8 V. For further information on external trimming, refer to
Chapter 5 of the Applications Manual or consult the factory for assistance.
