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.

INSPECTION & INSTALLATION

nitial inspection and preliminary checkout procedures
are recommended. For safe operation, please follow

I

the step-by-step procedures described in Chapter 3,

Operating Systems.

2.1 Initial Inspection

Inspect the package exterior for evidence of damage due
to handling in transit. Notify the carrier and Spellman
immediately if damage is evident. Do not destroy or
remove any of the packing material used in a damaged
shipment.

After unpacking, inspect the panel and chassis for visible
damage.

Fill out and mail the Warranty Registration card
accompanying the unit. Standard Spellman SL Series
high voltage power supplies and components are covered
by warranty. Custom and special order models (with an
X suffix and the model number) are also covered by
warranty.

2.2 Mechanical Installation

Units in the SL Series have front panel holes for standard
EIA rack mounting. The rack must allow rear access for
cable connections. Units are fully enclosed and are
suitable for bench or table top operation. Standard unit
dimensions are shown in Figure 2.1.
