INTRODUCTION

1.1 Description of the SL150

he SL150 voltage power supply provides very well
regulated, low ripple high voltage in a highly

T

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 200 (option) 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.

SL150 MANUAL 1 118093-001 REV B

1.2 Standard Features

The SL150 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.

 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 an d 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.

NOTE: Output power remote monitor is included with

the CPC and APT options, TB1 only.

SL150 MANUAL 2 118093-001 REV B

 INTLK CLSD: Indicates the EXTERNAL

INTERLOCK connections are in the closed position.
This also indicates closure of internal power supply
interlocks.

 INTKL OPEN: Indicates the EXTERNAL

INTERLOCK connections are in the open position.
This also indicates opening of internal power supply
interlocks.

 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.

 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.

 OVERPOWER: Indicates the output power has

exceeded the internally set level or the remote
programmed level if the optional circuitry is
installed.

 ARC: Indicates that an arc has occurred within the

previous one second or that the ARC COUNT/TRIP
has shutdown the power supply.

 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.

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.

OPERATING INSTRUCTIONS

3.1 Operation

WARNING

THIS EQUIPMENT GENERATES DANGEROUS

VOLTAGES THAT MAY BE FATAL.

PROPER GROUNDING OF ALL HIGH VOLTAGE

EQUIPMENT IS ESSENTIAL.

WARNING

BEFORE CONNECTING THE POWER SUPPLY

TO THE AC LINE, FOLLOW THIS STEP BY STEP

PROCEDURE.

DO NOT CONNECT THE POWER SUPPLY TO

THE AC LINE UNTIL STEP H IS REACHED.

Failure to follow these procedures may void the warranty.
A) Insure that the Circuit Breaker is in the OFF position

(0).

E) Plug the high-voltage output cable provided with the

unit into the rear of the supply and hand tighten the
knurled collar.

F) OPTIONS NOTE: See Section 5 for hook-up and

operating instructions for the options on your unit.
Custom models may also require set-up changes.

G) For initial turn-on, rotate the KILOVOLT control

fully counter-clockwise to the zero voltage position.

H) The input power cable may now be connected to the

AC power line.

I) Switch the front panel circuit breaker to the ON

position (1). (If the supply is to be turned off for an
extensive period of time, the line cord should be
disconnected). The unit is now in the HIGH
VOLTAGE OFF mode. The HIGH VOLTAGE OFF
light should be lit.

B) Check the input voltage rating on the nameplate of

the supply and make certain that this is the rating of
the available power source.

C) PROPER GROUNDING TECHNIQUES: The

chassis of high voltage power supplies must be
grounded, preferably to a water system ground using
copper pipe or other earth ground using the ground
stud B1 at the rear of the unit. See Figure 3.1 for a
typical operating set-up.

The return line from the load should be connected to
the ground stud on the rear of the power supply.
Using a separate external ground at the load is not
recommended.

D) Attach the output cable to the load.

SL150 MANUAL 7 118093-001 REV B

J) Depress and hold the HIGH VOLTAGE OFF switch.

The front panel meters will now read the preset value
of the KILOVOLT control dial and the
MILLIAMPERES control dial. To preset the desired
level of current and voltage during operation, hold in
the HIGH VOLTAGE OFF switch and rotate the
appropriate control dial while noting its
corresponding meter reading. Release the HIGH
VOLTAGE OFF switch.

NOTE: No actual output is being produced at this stage.
K) Depress the HIGH VOLTAGE ON switch. The light

inside the switch should light up and the output will
slow start to the preset level output voltage and/or
output current.

NOTE: The SL Series is equipped with a slow start

circuit that ramps the output up to its maximum
setting in approximately 6 seconds after the HIGH
VOLTAGE ON switch is depressed.

L) To terminate the generation of output power, depress

the HIGH VOLTAGE OFF switch. In the HIGH
VOLTAGE OFF mode the power supply’s fault and
interface circuits are still active.

M) To turn off the power supply, turn the circuit breaker

to the off position (0).
NOTE: If a power supply fault, or system

monitoring fault occurs, the power supply will revert
to the POWER DOWN mode. In this mode the
output power will be turned off. The HV OFF lamp
will be off. To reset, depress the HV OFF switch.

AFTER TURNOFF, DO NOT HANDLE THE LOAD

WARNING

CAUTION

ALWAYS OPERATE THE UNIT WITH THE COVER

A fan maintains safe operating temperature in the power
supplies by drawing air over the circuit components. The
cover must be on in order to direct the air flow over the
areas that need cooling. In operation, the unit must be
placed so that the air intake and the fan exhaust are clear
of obstructions that might impede the flow of air.

ON.

3.2 Standard Features

A note on remote interface circuitry and remote signal
grounding. Whenever possible, electrical isolation should
be provided when interfacing with any high voltage
power supply. For power control signals such as
EXTERNAL INTERLOCK, HIGH VOLTAGE OFF,
AND HIGH VOLTAGE ON, isolated relay contacts
should be used. For status signals and control signals
such as HIGH VOLTAGE ON, HIGH VOLTAGE OFF,
and EXTERNAL INHIBIT, etc., opto-isolation should be
used. If possible, analog programming and monitoring
signals should be isolated via analog isolation amplifiers.
Spellman application engineers are available to assist in
interface circuitry design. All interface cables should be
properly shielded. All power supply signals should be
referenced to the power supplies signal ground on the rear
external interface.

 REMOTE PROGRAMMING: Allows remote

adjustment of the output voltage and current via an
external voltage source. (Output power is also
remotely controllable with the CPC and APT
options). In local control (front panel control),
jumpers are installed on the external interface JB4 in
the rear of the chassis between JB4-10 and JB4-11
for voltage control and between JB4-8 and JB4-9 for
current control.

For remote programming, the jumpers are removed and a
positive voltage source, from 0V to 10 V, is applied to the
appropriate terminals. Programming signals should be
referenced to JB4-1, signal ground. By adjusting the
voltage source from 0V (zero output) to 10V (full rated
output), the desired output can be selected. See Figure

3.2A on page 12 for the wiring diagram and

specifications.
An alternate method of controlling the output remotely is

by using external resistance, such as a potentiometer or a
resistor network. For remote control the jumpers are
removed and the desired register configuration installed.
See Figure 3.2B on page 12 for the wiring diagram.

SL150 MANUAL 8 118093-001 REV B

 REMOTE MONITOR: Test points are made

available at the terminal block on the rear of the
chassis for monitoring the voltage and current output.
(Output power monitor is included with the CPC and
APT option). The test points are always positive
regardless of the output polarity where 0V to 10V
equals 0 to 100% of the output 0.5%. Test points
have an output impedance of 5K ohms. See Figure

3.3 on page 13 for the test point designation.

 REMOTE CONTROL: Remote control of the

HIGH VOLTAGE ON and HIGH VOLTAGE OFF
can be accomplished via the rear panel interface.
HIGH VOLTAGE OFF and HIGH VOLTAGE ON
can be controlled by momentary normally closed and
normally open contacts respectively. See Figure 3.4
on page 13 for the recommended interface.

 EXTERNAL INHIBIT: Allows the user to inhibit

the power supply output without switching HIGH
VOLTAGE OFF control. This circuit can be used to
generate fast slewing output waveforms or control of
high voltage generation as in Laser and Capacitor
discharge applications. The maximum inhibit rate
should not exceed 5Hz. Consult the factory for
higher repetition rates or high pulse load
applications. See Figure 3.5 on 14 for the
recommended interface circuit.

WARNING

IT IS EXTREMELY DANGEROUS TO USE THIS

INHIBIT CIRCUIT TO INHIBIT HIGH VOLTAGE

GENERATION FOR THE PURPOSE OF

SERVICING OR APPROACHING ANY AREA

OR LOAD CONSIDERED UNSAFE

DURING NORMAL USE.

 EXTERNAL INTERLOCK: Interlock connections

are provided on JB4-3 and JB4-4 on the rear of the
chassis for connection to a safety switch. The unit
will not operate unless the interlock circuit is closed.
If the interlock is not being used, the jumper installed
on the terminals before shipping must be in place. If
the jumper is missing, or there is an opening between

the interlock terminals, the unit’s high voltage
inverter will be disabled. During high voltage
operation, revert to the HIGH VOLTAGE OFF
mode. Subsequent closing of the interlock circuit
will NOT return the unit to the HIGH VOLTAGE
ON mode. This must be accomplished by depressing
the HIGH VOLTAGE ON switch. See Figure 3.6 on
page 14 for the recommended interface circuit

 ARC DETECT / ARC QUENCH / ARC COUNT:

The ARC DETECT circuit senses dynamic arcing or
discharge conditions present at the output load. If an
arc occurs, the output is inhibited for one second.
After the one second period, the output is ramped up
to the previous set level. This ramp is based on the
standard six second slow start feature. The ARC
DETECT ramp circuit may be disabled by removing
CR32 on the Control/Power Pwb. Caution should be
observed if this feature is disabled. Discharge rates
of greater then 1Hz may cause excessive power
dissipation in the power supply’s output limiting
resistors.

The ARC COUNT feature will allow the user to program
the ARC fault parameters. The ARC indicator on the
front panel will illuminate for approximately one second
after each arc has occurred. The power supply can be
programmed to trip the POWER DOWN mode if an arc
occurs.

The standard feature is programmed to trip the power
supply if 8 arcs occur within a twenty second period.

 REMOTE HIGH VOLTAGE ON & REMOTE

PRINCIPLES OF OPERATION

The SL150 high voltage power supply utilizes
sophisticated power conversion technology. A variety of
analog, digital and power conversion techniques are used
throughout. The intention of the Principles of Operation
is to introduce the basic function blocks that comprise the
SL power supply. For details on a specific circuit,
consult Spellman’s Engineering Department.

 Due to the many variations within the SL Series,

drawing numbers may differ from unit to unit.

The SL power supply is basically an AC to DC power
converter. Within the power supply, conversions of AC
to DC then to high frequency AC, then to high voltage
DC take place. By reviewing further the sub-assemblies,
a basic understanding of the process can be gained.

4.1 Chassis

The SL is a compact, high efficiency, high voltage power
supply. The power supply can supply up to 1200 watts of
DC power.

The energy levels used and generated by the
power supply can be lethal! Do not attempt to
operate the power supply unless the user has a
sufficient knowledge of the dangers and hazards
of working with high voltage. Do not attempt to
approach or touch any internal or external
circuits or components that are connected or
have been connected to the power supply. Be
certain to discharge any stored energy that may
be present before and after the power supply is
used. Consult IEEE recommended practices for
safety in high voltage testing #510-1983.

WARNING

SL150 MANUAL 17 118093-001 REV B

4.2 High Voltage Transformer

The output of the High Frequency Resonant Inverter is
connected to the primary of the High Voltage
Transformer. The High Voltage Transformer is a set up
type.

4.3 High Voltage Assembly

The High Voltage Assembly typically consists of various
parallel, series arrangements of a full wave voltage
doubler.

Output filtering is typically provided by an R-C type
filter. Voltage feedback for regulation and monitoring is
provided by a high bandwidth resistive/cap acitive divid er.
Current feedback for regulation and monitoring is
provided by a sense resistor connected at the low voltage
end of the High Voltage Rectifier/Multiplier Circuit.

4.4 Control/Power PWB

The majority of control circuits for power supply controls
are located on the CONTROL/POWER PWB. +15VDC, ­15VDC, and +10VDC is generated on the
CONTROL/POWER PWB. High Voltage On/Off control
is accomplished by K3, and its associated circuitry.
Interlock control is provided by K4.

Voltage feedback from the high voltage divider is sent to
the control board via a mass terminated ribbon cable.
Gain adjustment is provided on the HV PWB. The kV
feedback signal is sent to the front panel DVM and to the
REAR PANEL D- CONNECTOR for remote monitoring.
K2 provides switching between feedback and program
signal for the front panel DVM’s. This allows the user to
preset the desired output before energizing high voltage.

Program voltages are typically ramped up to set level by a
slow start circuit.

An arc sense circuit provides sensing, quench and
indicator of arc conditions. Consult the operation manual
for a detailed description of the arc sense control.

Current feedback from the high voltage rectifier is sent to
sense resistors located on the High Voltage Assembly.
Calibrated feedback is then sent to the applicable circuitry
on the Control/Power Board.

U12 circuit provides visual indication of the control
mode, which is in operation. These signals are sent to the
FRONT PANEL ASSEMBLY for front panel status
indication.

The resonant control circuitry consists of a pulse width
converter. U17 generates all frequency and pulse width
control signals.

Power supply inhibit circuits are provided by U22 and
K3. System Fault control and Indication is provided by
U19 and associated circuitry. Diagnostic signals are
latched and then sent to the FRONT PANEL
ASSEMBLY for status indication.

4.5 Front Panel Assembly

Front Panel controls, meters and status indications are
connected to the FRONT PANEL PWB. The FRONT
PANEL PWB interfaces directly to the
CONTROL/POWER PWB.

4.6 Options

Due to the many variations of models and options
provided in the SL150, details of actual circuits used may
differ slightly from the above descriptions. Consult
Spellman’s Engineering Department for questions
regarding the principles of operation for the SL Series.

SL150 MANUAL 18 118093-001 REV B

Chapter 5

OPTIONS

he options available for this power supply are
described in this section. Interface diagrams are

T

shown where required. Options are specified by
including the option code in the model number as
described in Section 1.5.

5.1 Adjustable

Overload Trip --AOL

The overload trip protection feature rapidly shuts down
the high voltage output when the current exceeds the limit
set by the current control dial on the front panel. A fast
acting circuit inhibits the generation of high voltage and
reverts the unit to POWER DOWN mode, illuminating
the OVER CURRENT indicator. When adjustable
overload trip is provided, it replaces the standard current
regulation feature.

5.2 200Vac Single Phase

Input--200

SL Series power supplies with the 200Vac input option
will operate from an input voltage of 200Vac RMS
10%, 50 to 60Hz, single phase.

5.3 No Slow Start--NSS

The no slow start option causes the output voltage of the
power supply to rise (within 50 msec) to the rated voltage
upon depressing the HIGH VOLTAGE ON switch.

5.4 Non-Standard Slow

Start--SS(x)

The non-standard slow start option allows the gradual rise
time of the output voltage to be different from the
standard of six seconds. To order the option place the
time desired in seconds after the suffix letter, i.e. SS (10)
denotes a 10 second rise time.

5.5 Extra Length Output
Cable--LL(ft)

Standard output cable is 10 feet of shielded high voltage
cable. Other lengths may be specified in multiples of 10
feet.

5.6 Arc Trip Option--AT

When this option is ordered, the Arc Count circuit is set
so the unit trips to Standby after 1 count. One of the
applications for this option is for sensing a material
breakdown under an applied high voltage.

5.7 Reversible

Polarity Option--PN

5.8 Adjustable Power

Trip/Constant Power Control
APT/CPC Option

The power control options allow monitoring and control
of the power supply output power. The APT option
allows the user to remotely adjust the power limit for the
power supply. If the power limit is exceeded, the unit
will shut down with an OVERPOWER fault. The CPC
option allows power regulation via an internal preset
potentiometer, or a remote program source. When the
unit is in power regulation, the POWER CONTROL
status indicator will be illuminated. See Figure 5.1 for
remote interface.

SL150 MANUAL 19 118093-001 REV B

5.9 External Fault Relay Option
EFR

The external fault relay option provides a set of customer
accessible relay contacts that are controlled by the fault
status circuitry of the applicable SL Series power supply.
A standard SL power supply will revert to the “power
down” mode with a visual front panel indication if any of
the following fault conditions occur:

 Overvoltage: Greater than 110% of maximum

output voltage was produced by the power supply.

 Overcurrent: Greater than 104% of maximum

output current was produced by the power supply or
the AOL circuitry was activated.

 Overtemperature: Excessive temperature has been

sensed within the chassis.

 Regulation Error: Lack of required output power to

maintain regulation

 Arc (Shutdown): Arc sensing circuit has shut down

the supply due to excessive arcing.

 Overpower: The power supply has exceeded the

internally set power limit level, if such circuitry is
installed.

With the installation of the EFR option, if any of these
faults occur, a relay will be activated to provide a remote
indication that the power supply has reverted to the
“power down” mode. The common, normally open and
normally closed set of contacts are provided. Relay
contacts are rated at 1A at 30Vdc or 0.5A at 48Vac.

Resetting the front panel and EFR relay is accomplished
by depressing the green front panel HV OFF push-button
switch, which reverts the power supply back to the
“standby” mode. Removal and reapplication of the AC
line input voltage will also reset any fault.

The circuitry and components required for the EFR
option are installed at the factory when this option is
ordered.

5.10 No ARC Detect Option NAD

The No ARC Detect option may be utilized by removing
CR32 on the control board. Caution should be observed
if this feature is disabled. Discharge rates of greater than
1Hz may cause excessive power dissipation in the power
supply’s output limiting resistors.

5.11 Remote Fault Reset Option
RFR

Allows the user to remotely reset a fault by momentarily
grounding JB4-12.

5.12 Custom Designed Models-X#

Units built to customer specification are assigned an X
number by the factory. If this unit is an X model, a
specification control sheet is added at the end of the test
of this instruction manual.

Spellman welcomes the opportunity to customize units to
fit your requirements or to develop new products for your
applications. Contact the Spellman Sales Department
with your needs.

HIGH VOLTAGE IS DANGEROUS.

ONLY QUALIFIED PERSONNEL SHOULD

PERFORM THESE TESTS.

High voltage test procedures are described in Bulletin
STP-783, Standard Test Procedures for High Voltage
Power Supplies. Copies can be obtained from the
Spellman Customer Service Department. Test equipment,
including an oscilloscope, a high impedance voltmeter,
and a high voltage divider such as the Spellman HVD­200 is needed for performance tests. All test components
must be rated for operating voltage.

6.3 High Voltage Dividers

High voltage dividers for precise measurements of output
voltage with an accuracy up to 0.1% are available. An
HVD-200 measures up to 200kV. The Spellman divider
is designed for use with differential voltmeters or high
impedance digital voltmeters. The high input impedance
is ideal for measuring high voltage low current sources,
which would be overloaded by traditional lower
impedance dividers.
