IO Instant On
A jumper is placed between TB1-15 and TB1-16
on the rear panel, causing the power supply to
automatically toggle into HV ON when ever the line
voltage is applied.
PN Positive/Negative
Reversible polarity option. Units that are not inher-
ently reversible by design (10kV to 130kV) can
have their output polarity reversed by the process
of exchanging the high voltage multiplier section.
EFR External Fault Relay
A set of relay contacts are provided via the rear
panel interface that will change state if the power
supply shuts down due to a fault condition.
ROV Remote Over Voltage
The programming signal for the over voltage com-
parator circuit is made available to the customer
remotely, allowing the power supply to be set to trip
the OVP circuit anywhere from 0 -110% of rated
output voltage.
CMS Current Mode Select
A front panel switch is provided to allow the power
supply to either regulate in current mode or create
an over current fault when operated in current
mode, which will shut down the supply. This is
basically a switch selectable AOL option.
DPM4 Digital Panel Meter, 4.5 digits
The standard 3.5 digit front panel meters are
replaced with 4.5 digit panel meters.
AT Arc Trip
A control board jumper is moved such that the first
arc sensed will shut the power supply off with an
ARC fault.
BPM Bipolar Master
BPS Bipolar Slave
This option configures two identical but opposite
polarity units to function as a single tracking
bipolar supply. The voltage feedback of the master
(positive unit) is provided to the voltage
programming input of the slave (negative unit).
FCV Fine Control Voltage
This option adds a second potentiometer to the
front panel of the unit. This allows for a finer local
adjustment of the output voltage setting.
NAD No Arc Detect
This option removes the arc intervention circuitry
from the power supply. Care must be exercised
when using this option as damage to the HV
multiplier could occur.
RFR Remote Fault Reset
This option provides the ability to reset any power
supply faults that might occur via toggling a
signal on the rear panel interface.
There may be some restrictions on multiple option combinations.
Please contact our Sales department for more details.

SL SERIES OPTIONS
AOL Adjustable Overload Trip
A control board jumper is moved to make the
power supply shut down if it ever operates in
current mode. This allows the user to set the cur-
rent programming level as a trip point that will
turn the power supply off with an Over Current
fault if it ever tries to operate in Current Mode.
FG Floating Ground
All the analog returns inside the power supply are
isolated from chassis and brought to one point
on the rear panel. Any current that flows out of
the power supply via the HV cable/connecter on
the high side must return back to the multiplier
via the load return on the low side. With only one
path to flow through on the low side, a current
meter can be inserted in series and a safe
ground referenced measurement can be made of
the actual high voltage output current.
FGLLFloating Ground Low Leakage
Identical functionality as the FG Option but a shield
is placed around the high voltage multiplier to cap-
ture any leakage current inside the power supply
and return it to the top of the current sense resistor.
This negates any internal leakage currents from
effecting measurements being made.
LR Low Ripple
Done on a case by case basis, the standard unit is
evaluated and modifications are done to improve
the output ripple to 0.05% peak to peak. The oper-
ating frequency might be increased, or additional
filtering may be added to the HV multiplier.
NSS No Slow Start
The standard 6 second long linear ramp of output
voltage is removed allowing the high voltage to
“step” to its set point when enabled.
SS(X)Slow Start(X)
The standard slow start is modified to provide a
time of (X) seconds. Time frames of 0.1 seconds
to 120 seconds can be accommodated.
ATP Adjustable Power Trip
A third control loop is installed in the power supply,
a power loop. This power loop uses an analog
multiplier chip to multiply the voltage and current
feedback signals to create a power feedback
signal. Programming and feedback scaling is 0-
10Vdc = 0-100% of rated power. The circuit is
configured to trip the power supply off with an Over
Power fault if the power loop ever tries to regulate.
CPC Constant Power Control
Identical to the ATP Option with the exception the
power supply will run and regulate when the
power loop becomes active.
SL Slides
Industry standard rack mounted slides are installed
on the power supply.

INTRODUCTION
1.1 Description Of The SL Series
he SL Series of high voltage power supplies provides
very well regulated, low ripple high voltage in a
highly efficient, compact design. The improvements
in size and performance over traditionally designed high
voltage power supplies are due to the resonant topology
and unique control circuitry of the SL design. A
proprietary control system maintains high frequency over
the operating output range. High frequency operation
allows a dynamic response time of less than 5
milliseconds, and one of the lowest ripple specifications
in the industry at this power level. The combination of
proprietary control system and proprietary protection
circuitry enables the supplies to operate under arcing and
extreme transient conditions without damage or
interruptions.
The DC output voltage and current are continuously
adjustable from zero to the maximum rating via two front
panel ten-turn locking potentiometers. These high
voltage power supplies have 0.005% load regulation,
0.005% line regulation, and 0.1% p-p ripple.
The supplies operate from either a 115 or 220 Volt, single
phase AC line. Other line voltages are available. Options
are listed in Table 1.1 and are described in Section 5.
Custom designed units to meet special needs are also
available.
T

1.2 Standard Features
The SL Series incorporates several standard features
designed to optimize user satisfaction and safety.
•SLOW START: This feature provides a gradual
increase in high voltage until the preset operating
point is reached. The slow start time is factory set
for 6 seconds. Other slow start times are available as
an option.
•ARC DETECT / ARC QUENCH / ARC COUNT:
These features allow the user to tailor the power
supply to meet specific needs in dynamic load
applications. If an arc occurs, the output is inhibited
for approximately one second, then the output is
ramped up to the preset level with the slow-start
circuitry. See Chapter 3 for operating details and
information for user customization of these features.
•INTERNAL FAULT PROTECTION: The SL
Series continually monitors internal circuits critical to
the proper operation of the power supply. In the
event that one of these circuits does not function
correctly, the fault detection circuit latches the
appropriate fault on the front panel display and turns
off the output and reverts the unit to the POWER
DOWN mode.
•INDICATOR LAMPS: LINE POWER, HIGH
VOLTAGE OFF AND HIGH VOLTAGE ON
indicators.
•OUTPUT CABLE: All models are provided with a
ten foot shielded high voltage output cable. The
cables are designed with a plug arrangement so that
they can be easily removed from the mating
receptacle located on the rear of the chassis.
1.2.1 Remote Operating Features
•REMOTE PROGRAMMING: Allows remote
adjustment of the output voltage and current via an
external voltage source. The output power is also
remotely controllable when the CPC or APT option
is ordered, TB1 only.
•REMOTE MONITOR: Allows remote monitoring
of the output voltage and current.
NOTE: Output power remote monitor is included with
the CPC and APT options, TB1 only.
•REMOTE HIGH VOLTAGE CONTROL:
Allows remote control of HIGH VOLTAGE ON and
HIGH VOLTAGE OFF. Signals are also provided
for remote indication of HV ON or HV OFF status.
•EXTERNAL INHIBIT: A control signal that will
inhibit the high voltage output is provided on the
external interface. A logic low, ground, will inhibit
the high voltage output and a logic high, open, will
restore the high voltage output to the preset level.
NOTE: The External Inhibit circuit should NOT be used
for protection against injury or for safety interlock.
See External Interlock for this type of safety control.
•EXTERNAL INTERLOCK: Interlock connections
are provided on the external interface on the rear of
the chassis for connection to a safety switch. The
unit will not operate unless the interlock circuit is
closed. During high voltage operation, opening the
interlock circuit will cause the High Voltage to shut
off. This circuit should be used for safety interlock
circuits.
1.2.2 System Status and Fault
Diagnostic Display
“Dead Front” type indictors are provided to give the user
complete indication of system operation and fault
conditions. If a fault occurs, the power supply will revert
to the POWER DOWN mode. This is indicated by both
the HV ON and HV OFF lamps turning off. To reset,
depress the HV OFF switch.
•VOLTAGE (CONTROL): Indicates the output
voltage regulator circuit is maintaining voltage
regulation.
•CURRENT (CONTROL): Indicates the output
current regulator circuit is maintaining current
regulation.
•POWER (CONTROL): Indicates the output power
regulator circuit is maintaining power regulation
(optional).
•HV INHIBIT: Indicates that the high voltage
supply is being inhibited by either the EXTERNAL
INHIBIT or internal protection circuitry.
SL SERIES MANUAL 2 118006-001 REV T
•INTLK CLSD: Indicates the EXTERNAL
INTERLOCK connections are in the closed position.
This also indicates closure of internal power supply
interlocks.

1.3 Options
AOL
•INTKL OPEN: Indicates the EXTERNAL
INTERLOCK connections are in the open position.
This also indicates opening of internal power supply
interlocks. Adjustable Overload Trip (0-103%)
OL Overload Trip (103%)
•OVERVOLT: Indicates the overvoltage protection
circuitry has caused the power supply to turn off.
Overvoltage protection is internally set to 110% of
the rated output voltage.
APT Adjustable Power Trip
AT Arc Trip
•OVERCURR: Indicates the output current has
exceeded the programmed current trip level when the
AOL (Adjustable Overload Trip) or the OL
(Overload Trip) options are installed.
FG Floating Ground
FGLL Floating Ground, Low Leakage (10mA)
•OVERPOWER: Indicates the output power has
exceeded the internally set level or the remote
programmed level if the optional circuitry is
installed.
CPC Constant Power Control
SS(x) Non-Standard Slow Start
•ARC: Indicates that an arc has occurred within the
previous one second or that the ARC COUNT/TRIP
has shutdown the power supply. NSS No Slow Start
IO Instant ON
•RGLT ERR: Indicates a failure in the voltage,
current or power regulation circuitry. This fault
usually occurs when there is a lack of output power
to maintain regulation.
LR Low Ripple (0.05% p-p)
( ) Specify 220V or 100V or 200Vac Single Phase
Input With Order.
The options available are listed in Table 1.1. See Section
5 for more information on these options along with
operating and set-up instructions. With few exceptions,
these options and modifications can be retrofitted to your
power supply at the factory in a short time. For price and
retrofit arrangements, contact the Spellman Sales
Department.
