INTRODUCTION
1.1 Description of the SL150

T he SL150 voltage power supply 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 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.

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

 SPELLMAN HIGH VOLTAGE ELECTRONICS
WARRANTY
Spellman High Voltage Electronics (“Spellman”) warrants that all power supplies it manufactures will be
free from defects in materials and factory workmanship, and agrees to repair or replace, without charge, any
power supply that under normal use, operating conditions and maintenance reveals during the warranty
period a defect in materials or factory workmanship. The warranty period is twelve (12) months from the
date of shipment of the power supply. With respect to standard SL power supplies (not customized) the
warranty period is thirty-six (36) months from the date of shipment of the power supply.

This warranty does not apply to any power supply that has been:
• Disassembled, altered, tampered, repaired or worked on by persons unauthorized by Spellman;
• subjected to misuse, negligent handling, or accident not caused by the power supply;
• installed, connected, adjusted, or used other than in accordance with the original intended application and/or
instructions furnished by Spellman.

THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
THOSE OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

The buyer’s sole remedy for a claimed breach of this warranty, and Spellman’s sole liability is limited, at
Spellman’s discretion, to a refund of the purchase price or the repair or replacement of the power supply at
Spellman’s cost. The buyer will be responsible for shipping charges to and from Spellman’s plant. The
buyer will not be entitled to make claim for, or recover, any anticipatory profits, or incidental, special or
consequential damages resulting from, or in any way relating to, an alleged breach of this warranty.

No modification, amendment, supplement, addition, or other variation of this warranty will be binding unless
it is set forth in a written instrument signed by an authorized officer of Spellman.

Factory Service Procedures

For an authorization to ship contact Spellman’s Customer Service Department. Please state the model and
serial numbers, which are on the plate on the rear panel of the power supply and the reason for return. A
Return Material Authorization Code Number (RMA number) is needed from Spellman for all returns. The
RMA number should be marked clearly on the outside of the shipping container. Packages received without
an RMA Number may delay return of the product. The buyer shall pay shipping costs to and from Spellman.
Customer Service will provide the Standard Cost for out-of-warranty repairs. A purchase order for this
amount is requested upon issuance of the RMA Number (in-warranty returns must also be accompanied by
a “zero-value” purchase order). A more detailed estimate may be made when the power supply is received
at Spellman. In the event that the cost of the actual repair exceeds the estimate, Spellman will contact the
customer to authorize the repair.

Factory Service Warranty

Spellman will warrant for three (3) months or balance of product warranty, whichever is longer, the repaired
assembly/part/unit. If the same problem shall occur within this warranty period Spellman shall undertake all
the work to rectify the problem with no charge and/or cost to the buyer. Should the cause of the problem be
proven to have a source different from the one that has caused the previous problem and/or negligence of
the buyer, Spellman will be entitled to be paid for the repair.
