MICRO-SIZED HIGH VOLTAGE POWER SUPPLIES
ULTRAVOLT® US SERIES
Single-output
micro-sized HV
modules
Measuring only 5.75 cc (0.35 in
3
), the highly compact,
micro-sized US series
is specially designed to meet the
needs of design engineers working with commercial,
military, industrial, and medical applications. These modules
allow access to voltages up to 500 V for customers with
size-critical requirements.
