ULTRAVOLT SINGLE-OUTPUT AND BIPOLAR
MICRO-SIZED HV MODULES
PXS SERIES PROPORTIONAL EXTRA-SMALL
HIGH VOLTAGE POWER SUPPLY
The PXS Series of proportional extra-small high
voltage power supplies has excellent load regulation
characteristics,
as well as superior temperature stability
performance. The small size of the units, ease of control,
and high stability, make the PXS Series optimal for hand-
held devices, portable equipment, and other small high
voltage projects.

Please contact the factory for more information.
Notes: Output is isolated from the input by 1 kV. Either output can be
floating ground or grounded, thereby setting output polarity to + or -.
The PXS Series only has intermittent short-circuit protection.
