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.
