MEASUREMENT AND CALIBRATION INSTRUMENTS High Voltage DC Power Supplies

Bertan's brand of Spellman PMT modular high-voltage power supplies offers well-regulated fixed-polarity outputs up to 7.5 kV, which operate with low DC input voltage. These fully enclosed modules are specifically designed with proprietary linear energy conversion techniques to provide exceptionally low ripple and noise levels. The PMT series is ideal for precision applications including: photomultiplier tubes, solid state detectors, and ultrasonic transducers.

The voltage output can be controlled either by an internal local potentiometer or by a customer supplied ground reference signal for remote operation. Additionally, a ground reference output voltage monitoring signal is provided. The PMT series can be powered from a single positive voltage source or a ± divided voltage source, providing flexibility in application.

Typical applications:

  •     Photomultiplier tubes
  •     Ultrasonic transducers
  •     Solid state detectors

Input Voltage: 

Option 1: +24Vdc to +30Vdc @ 400mA

Option 3: ±12Vdc to ±18Vdc @ 400mA
