High Voltage Power Supply

SLS MANUAL 118131-001 Rev A

The SLS series of high voltage power supplies provide up
to 2000 watts of power with voltage outputs ranging from
160kV to 360kV. These power supplies utilize high frequen­cy resonant inverters with proprietary controls for reliable
operation in extreme environments. The high voltage multi­plier unit is built with a hybrid design of solid encapsulation
and air, thus reducing its overall size. Comprised of 20kV
interlocking wafers, the multiplier unit offers flexible building
blocks for many different output configurations.

Chapter 1

INTRODUCTION

1.1 Description of the SLS Series

he SLS Series of high voltage power supplies
provides very well regulated, low ripple high voltage

T

in a highly efficient, compact design. The
improvements in size and performance over traditionally
high voltage power supplies are due to the resonant
topology and unique control circuitry of the SLS Series.
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. The combination of the proprietary
control and protection circuitry enables the supplies to
operate under arcing and extreme transient conditions
without damage or interruptions.

The SLS Series offer outputs from 160kV to 360kV via
an inverter chassis and separate high voltage “stack”
assembly. The necessity of the stack is simple, as output
voltages increase to 160kV and beyond, economical and
reliable cable/connecter assemblies become less available
and more problematic to incorporate. The solution is to
remove the cable/connecter assembly and to make the
output voltage available via the top of a separate air
insulated high voltage stack assembly. SLS units typically
have two assemblies: the inverter chassis and the air
insulated high voltage stack.

Danger – Electrocution Hazard!

The top corona dome assembly of the SLS is at high
voltage. It is the responsibility of the user to:

a) Make appropriate electrical connection to the

corona dome assembly.

b) Assure the corona dome assembly is adequate to

suppress corona in their particular usage and
application, additional customer provided corona
relief might be required.

c) Assure adequate air insulation spacings are used

in the setup and mounting of the stack assembly
(minimum of 1 inch for each 10kV of high
voltage).

d) Make certain the entire high voltage stack

assembly in contained in a grounded, protective

Faraday Cage with an interlocked access door.

SLS units generate lethal voltages; they require
appropriate high voltage safety knowledge to safely setup
and use. If you are not properly trained and qualified:
STOP! DO NOT PROCEED! DO NOT USE THIS
EQUIPMENT!
