Overview
The FlatPAC-EN/EN MI is an ultra-low-profile switching power supply that provides up to 500W from
up to four isolated outputs. It operates on either 115 or 230VAC nominal (47 – 63Hz), or 250 – 380VDC.
It can be populated with either VI-200/VI-J00 or Maxi/Mini/Micro Vicor converters. The use of these
converters gives the FlatPAC-EN/EN MI the inherent power flexibility typical of all Vicor products. With
dimensions of 1.4in H [35,6mm] x 5.0in W [127mm] x 9.2in L [233,7mm], the FlatPAC-EN/EN MI provides
a power density greater than 7W/in3. It is factory configured to meet user output requirements.
Note: The FlatPAC-EN/EN MI does not have an internal fan.
The MI version is a rugged chassis designed specifically for COTS and harsh environment applications.

Mechanical Considerations
The FlatPAC-EN™/EN MI is mounted on the bottom surface using standard 8-32 or 4mm screws (cannot
be mounted from the front.)
Maximum allowable torque is 5in.lbs. The maximum penetration for mounting holes A1, A2, A3
and A4 is 0.125in [3mm] and for mounting holes B1, B2, C1 and C2 is 0.250in [6mm]. The minimum
recommended mounting holes are as follows:
1. For standard mounting (forced air cooling), use A1, A2, A3, A4 mounting holes.
2. For standard mounting (conduction cooling), use A1, A2, A3, A4, B1 and B2
mounting holes.
3. For a Vicor 2-Up FlatPAC™ retrofit replacement, use C1 and C2 as these two are identical to the
recommended mounting holes on the FlatPAC.
For increased ruggedness, additional mounting holes can be used to secure the power supply.
The FlatPAC-EN/EN MI does not have an internal fan. It can be either conduction or convection
cooled (same model).
Avoid excessive bending of output power cables after they are connected to the output terminals.
For high-current outputs, use cable ties to support heavy cables and minimize mechanical stress on
connectors. Be careful not to short-out to neighboring outputs. The maximum torque recommended on
output nuts is 10in.lbs.
For applications that require vibration levels above MIL-STD-810E, minimum integrity test, a
shock-absorbing mount design is required.

FlatPAC-EN™/EN MI Dos and Don’ts
 Do not exceed an operating case temperature of 90°C. To prevent an overtemperature condition,
an external fan may be required.
 Run the output (+/–) power cables next to each other to minimize inductance.
 Always turn the power supply off before disconnecting input or output wires.
 When using the remote-sense feature, the +OUT and –OUT load wires should never be disconnected
while the supply is operating. Failing to do so could damage the power supply.
 Do not attempt to repair or modify the power supply in any manner as this action will void the
warranty. In the event of problems, contact Applications Engineering at 1-800-927-9474.
 Insert proper fault protection at power supply input terminals (i.e., a fuse).
Refer to Page 13 for more information.
 Use proper size wires to avoid overheating and excessive voltage drop.
 Output voltages over 60VDC, whether from individual modules or series arrays, are considered
as hazardous secondary outputs under UL 60950. Appropriate care must be taken in design
implementation of the supply.
Technical Description
The FlatPAC-EN/EN MI consists of an off-line single-phase autoranging front end, EMI filter, customer
interface, power supply control circuit, associated housekeeping circuits, a MiniHAM™ module and a
selection of Vicor VI-200™/VI-J00™ and/or Maxi/Mini/Micro DC-DC converters.
The MiniHAM was specifically designed for EN compliance using passive filtering. Unlike active PFC
solutions, the MiniHAM generates no EMI, greatly simplifying and reducing system noise filtering
requirements. It is also considerably smaller and more efficient than active alternatives and improves
the unit’s MTBF. It will provide harmonic current compliance at 230VAC input up to 425W of output
power. Input AC mains voltage is applied to input connector MBJ1 (see Page 7) and the input current
is passed through an EMI filter designed to meet conducted noise limit of EN 55022, Classes A and B
specifications (certain configurations meet EN55022 Class B. Consult Factory.)
At start up, the microcontroller verifies that the input voltage is within the specified operating range.
Once this occurs, the microcontroller closes the safety relay and puts the autoranging front end in the
correct mode (closing or opening the doubler relay). The autoranging front end has two modes, the
doubler mode (90 – 132VAC) or bridge rectifier mode (180 – 264VAC, 250 – 380VDC). Inrush current
is limited by a PTC thermistor. The PTC is shunted out (by closing the Inrush relay) when the output
voltage has charged up the bus capacitors within the specified range (205 – 390VDC). Approximately
one second after the application of the input voltage, the bus voltage is within operating limits and the
AC OK signal asserts to a TTL "1", indicating the input power is OK. After AC OK is asserted high, the
user can now control the power outputs.
Output voltage conversion is achieved by Vicor 300VIN 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 efficiencies.

UG:120 Page 5
At initial power-up, all outputs are disabled to limit the inrush current and to allow the DC bus
potential to settle to the correct operating level. A low-power transformer flyback circuit converts the
high-voltage DC bus into regulated low voltage to power the internal housekeeping circuits as well as
the auxiliary +5VS located in the interface connector.
An output Enable/Disable function is provided to control Vicor DC-DC converters. If the Enable/Disable
control pin is pulled low, the modules output is disabled. The nominal delay associated for an output to
come up when measured from release of the Enable/Disable pin is 9 – 12ms. The General Shut-Down
function controls all outputs simultaneously and works in a similar manner.

Interface Connections
Chassis Input Power Terminals (MBJ1)
Input AC power is applied through connector MBJ1 using Molex mating connector 39-01-4051.
Use 16AWG wire with Molex Socket Pin 39-00-0090 and Crimp Tool 11-01-0199.
A fault clearing device, such as a fuse or circuit breaker, with a maximum 9A rating at the power supply
input is required for safety agency compliance. It should be sized to handle the start-up inrush current of
8.5A peak at 115VAC or 17A peak at 230VAC.
Output Power Connections
There are two types of output power terminals available in the FlatPAC-EN™. Each slot has one of the
following configurations: either 10-32 plated steel bolts or an 18-pin Molex connector (The type of
output connector a FlatPAC-EN has depends on which modules are used. See Pages 7 and 11. Molex
connectors are limited to 9A/pin, 27A per output) The positive polarity of the stud output termination is
the right bolt when viewed from the output end. Each power output is isolated, so outputs of positive
or negative polarity can be configured through proper selection of the output reference terminal.
In order to minimize parasitic cable inductance and reduce EMI, the output power cables should be
routed in close proximity to one another, and large current loops should be avoided. To avoid excessive
voltage drop, do not undersize power cables, especially for high-current outputs. Do not bulk input
AC wires with the output wires because this can couple output noise into the input wires which can
increase EMI. Excessive cable inductance coupled with large capacitive loading can introduce instability
in switching power supplies. This problem can be avoided with proper system design. Consult the Vicor
Applications Engineering Department for assistance with applications that use long cable lengths and
excessive load capacitance.

User Interface Connections
Signal Ground (CBJ1-1)
Signal Ground on CBJ1-1 is an isolated secondary ground reference for all CBJ1 interfacing signals. This
is not the same as earth ground on input power connector MBJ1.
AC OK (CBJ1-3)
AC OK is an active high TTL compatible signal and provides a status indication of the AC input power. It
is on pin CBJ1-3 and is capable of sinking 16mA maximum. This signal switches to a TTL "1" when the
high-voltage bus exceeds low-line condition during turn-on. Upon loss of input power, the bus voltage
will drop, causing the AC OK signal to go low. Typically, a 2.5ms hold-up time is provided for a 500W
load following the loss of the AC OK signal.
TRANSMIT/RECEIVE RS-232 Command Protocol (CBJ1-4 and CBJ1-5)
The FlatPAC-EN™/EN MI incorporates a microprocessor for communicating status and allowing user
control. A suitable Terminal Emulator must be used to communicate with this circuit. Operation in the
remote mode requires commanding the Power Supply to be a slave via the RS-232 interface.
Operating Modes
The FlatPAC-EN has two operating modes, remote and manual, which can be set using the RS-232
interface feature. The operating-mode setting is stored in a non-volatile EEPROM and requires an REON
or REOFF command in order to switch modes. The default mode setting from the factory is in manual
mode. The FlatPAC-EN has an operating mode indicator LED, which is viewable through the left side
vent hole nearest the CBJ1 E/D Interface Connector. When this LED is ON, the power supply is operating
in remote mode.

Communications Protocol
The protocol is an ASCII character stream that will be sent back and forth between the power supply
and the user. The FlatPAC-EN™/EN MI in the remote mode will be considered a slave in that it will only
respond to commands and requests and will not initiate conversations. Communications are half-duplex
in that only the FlatPAC-EN/EN MI receiver or transmitter may be active at one time. The unit will
reply to all commands or requests with a defined response followed by a carriage return and line feed
character pair (CR/LF). The user must wait for the reply from the FlatPAC-EN before issuing the next
command or request. The data bytes will have a format of 1 start bit, 8 data bits, 1 stop bit and no
parity at 9600 Baud.
Commands, Status Requests and Module Replies
All commands and requests will have a reply. The reply will be one of the following character strings
followed by a CR/LF character pair. "OK" – Issued when a command has been received and acted
upon and the command has no return data associated with it. "Inv Command" – Issued when an
unrecognized command has been received or a command cannot be executed at this time.
"Inv Range" – Issued when a command argument is not within a valid range.
The following is the list of commands and their definitions. All commands must be followed with
a CR/LF character pair.
PUP – Power Up
This command starts the automatic turn on timed sequence for the modules. If a power-down sequence
is active at the time this command is received, a reply of "Inv Command" is returned; otherwise
"OK" is returned.
PDN – Power Down
This command starts the automatic turn off timed sequence for the modules. This command can be
given at any time and will cancel any uncompleted automatic power-up sequences. "OK" is returned.
EMO – Emergency Off
This command turns all modules off. If either a power-up or power-down sequence is active at the time,
it will be terminated immediately. A response of "OK" is returned.

TON1, TON2, TON3, TON4
Turn On commands for modules 1, 2, 3, or 4.
These commands turn on the module identified by the trailing digit. If an automatic sequence is
in effect at the time this command is received, a reply of "Inv Command" is returned; otherwise
"OK" is returned.
TOFF1, TOFF2, TOFF3, TOFF4
Turn Off commands for modules 1, 2, 3, or 4.
These commands turn off the module identified by the trailing digit. If an automatic sequence is
in effect at the time this command is received, a reply of "Inv Command" is returned; otherwise
"OK" is returned.
SDON1, SDON2, SDON3, SDON4
Set Delay On Time for modules 1, 2, 3 or 4.
These commands set the associated time delays for the DC-DC converters to be activated via "PC" pin
release. There is an additional delay of up to 7ms inherent in the DC-DC converters. These commands
are entered with a trailing argument. The valid range of the argument is from 1 to 255 and is in
10-millisecond increments. The effective range of delay then becomes 10 – 2550 milliseconds or
0.01 – 2.55 seconds. Out-of-range arguments are replied to with an "Inv Range" message; otherwise
"OK" is returned. The delay times are effective and run concurrent from either power up of the unit or
from receipt of the power-up command. If these commands are entered without an argument then the
unit will report the present settings of these variables.
SDOFF1, SDOFF2, SDOFF3, SDOFF4
Set Delay Off Time for modules 1, 2, 3, or 4.
These commands set the associated time delays for the DC-DC converters to be deactivated via "PC"pin
release. These commands are entered with a trailing argument. The valid range of the argument is
from 1 – 255 and is in 10-millisecond increments. The effective range of delay then becomes
10 – 2550 milliseconds or 0.01 – 2.55 seconds. Out-of-range arguments are replied to with an "Inv
Range" message; otherwise "OK" is returned. The delay times are effective and run concurrent from
either receipt of the power-down command or from an error condition with the unit. If these commands
are entered without an argument then the unit will report the present settings of these variables.
BV – Bus Voltage Readback
This command returns the current bus voltage reading.
MS – Module Status
This command returns the module status as shown: MS = X1 X2 X3 X4 X5
X1 indicates the status of module output 1.
X2 indicates the status of module output 2.
X3 indicates the status of module output 3.
X4 indicates the status of module output 4.
A "1" indicates the output is up/on and ok and a "0" indicates the output is down/off.
X5 indicates the status of the power supply Bus. A "1" indicates BUS OK and a "0"
indicates BUS NOT OK.

UG:120 Page 17
SN – Serial Number
This command returns the serial number as set by factory (available only on request.)
REON – Remote Mode ON
This command put the power supply into the slave mode. In this mode the power supply will only
respond when commanded.
REOFF – Remote Mode OFF
This command put the power supply into the manual mode. In this mode the power supply will only
respond to the following commands via the RS-232 interface: REON, SN, SDON1, SDON2, SDON3,
SDON4, BV, MS, HST.
HST – Heat Sink Temperature
This command returns Temperature of the heat sink in degrees Celsius. Heat-sink temperature is
measured frequently and stored into EEPROM memory. Upon loss of power last measured value in
stored in EEPROM.
Enable/Disable Mode (CBJ1-8 and CBJ1-9)
The Enable/Disable control pins allow outputs to be sequenced either on or off.
CBJ1-4 through CBJ1-9 are the control pins for outputs 1 – 4. The Enable/Disable pins should be pulled
low to less than 0.7V with respect to signal ground to disable the outputs. They will source 9mA
maximum. These pins should be open circuited or allowed to exceed 4.5V when enabled. Do not apply
more than 5V to these inputs.
The correspondence between a module and its E/D line as seen from the output end of the power
supply goes from left to right.
General Shut Down /GSD (CBJ1-10)
The GSD control pin on CBJ1-10 allows simultaneous shut down of all outputs. This pin must be pulled
down to less than 0.7V and will source 9mA maximum to shut down all outputs. The GSD pin should be
open circuited or allowed to exceed 4.5V when not in use, or when the outputs are to be enabled. Do
not apply more than 5V to this input at any time. Normal open circuit voltage is 1.5 – 4V with respect
to signal ground.

Auxiliary VCC +5V/300mA (CBJ1-12)
The VCC on CBJ1-12 is an auxiliary 5V regulated power source. It is +5VDC ±5% with respect to Signal
Ground and can supply 300mA maximum. It is capable of withstanding a short, but shorted user
interface functionality will be lost.
+SENSE/–SENSE (J2) (Not applicable when using BatMod™ current source.)
The sense lines for the outputs are shipped from the factory with Autosense. Autosense provides the
user with automatic sensing of the outputs. With Autosense, the FlatPAC-EN™/EN MI will automatically
operate in a remote-sense mode when the remote-sense connections are made. But in the event that
the remote sense is not connected or needed, no local-sense selection is necessary – simply hook up the
outputs and the FlatPAC-EN will automatically operate in local-sense mode. 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 5Ω, then the output has Autosense and does not require local sense jumpers. When
using the remote sense feature, the +OUT and –OUT load wires should never be disconnected while the
supply is operating. Failing to do so could damage the power supply.
In the local sense mode (remote-sense lines not connected), the power supply will regulate the output
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, the
output can be trimmed up or configured for remote sense. Use stranded twisted pair 24 – 30AWG wire
for the remote-sense lines. Remote-sense can compensate for a voltage drop of up to 0.5V, or 0.25V
on each leg.
The sense connector for outputs with stud connectors is a 3-pin connector providing the +SENSE
connection on J1/ J2-2 and the –SENSE connection on J1/J2-3. The sense connector for outputs with
18-pin Molex connectors is provided on the 18-pin output connector that also provides the output and
trim connections. See Page 11 for details.
Note: Remote sense is not available for output configurations using the Micro modules.

External Trim (Not applicable when using BatMod™ current source)
The TRIM pin can be used for external control of the output voltage. TRIM connections on single-
and dual-output connector for output M1 is J1-1 while for output M2 is J2-2. TRIM connections on
triple-output connectors for output M1 is J2-6, for output M2 is J3-6 and for output M3 is J3-14. TRIM
connections for quadruple-output connectors on outputs M1 and M2 is J2-6 and J2-14 respectively, and
for outputs M3 and M4 is J3-6 and J3-14 respectively. A 10% increase to the trim pin voltage will result
in a 10% increase in output voltage. Reducing the trim pin voltage by 10% will result in a 10% decrease
in output voltage.
Example:
±10% Trim adjust on a 12V nominal output.
Figure 7 shows a typical variable trim circuit. Using a 10kΩ trimpot (R7), the resistor values for R6 and
R8 can be calculated as follows:
V1= VREF + 10% = 2.75V Given: VREF = 2.5V (see Table 1)
IR5 = (2.75V – VREF)/RTH = (2.75V – 2.5V) Given: RTH = 10kW (see Table 1)
/10kW = 25mA
Setting the bottom limit:
VR6 = 2.5V – 10% = 2.25V
And since IR5 = IR6 = 25mA,
R6 = VR6/IR6= 2.25V/25mA = 90kW
V2= V1+ VR6 = 2.75V + 2.25V = 5V
IR7 = V2/R7 = 5V/10kW = 500mA
IR8 = IR7 + IR6 = 525mA
VR8 = (VNOM +10%) – V2= 13.2V – 5V = 8.2V Given: VNOM = 12V
R8 = VR8/IR8 = 8.2V/525mA = 15.62kW
