Extra-Small High Voltage Biasing Supply

Single-output micro-sized HV modules
The XS series of extra-small high voltage power supplies is the smallest regulated DC-to-DC high voltage power supply for applications that require a bias voltage ranging from 0 to 100 V. Measuring only 1.3 cc (0.08 in3 ), these modules are ideal for use in size-critical applications.
