HPR Series

Precision High Voltage Modules

HP001R, HP2.5R, HP005R, HP010R, HP015R, HP020R, HP030R

Applications: Photomultiplier tubes, Mass spectrometers, Electron microscopes, Nuclear instruments, Microchannel plates

  • 0.5kV, 1kV, 2.5kV, 5kV, 10kV, 15kV, 20kV & 30kV
  • High Stability, Low Ripple
  • High frequency FET oscillator
  • Externally programmable or Internal control (option)
  • 24 hour burn in
  • Low radiated magnetic field
  • Positive, negative & remote reversible versions

This range of precision high voltage modules has outputs that provide a low ripple, high stability source of high voltage for photomultiplier tubes, electron gun, nuclear and other applications. Control of the output voltage is by internal potentiometer or by an external 10 volt analogue control voltage. The units are pin compatible with the medium stability KS and 100 watt HW ranges.

All units are short circuit proof and use proven linear regulator techniques to drive a high frequency FET oscillator and ferrite high voltage step-up transformer. The power supplies are constructed from conservatively rated components with the reliability further enhanced by information gained over many years of field operation.

Positive, negative, and electrically reversible outputs are available at voltages from 1kV to 30kV. This reversible HPR version has a latched output and can only be changed when the output is set to zero. Please see the HPZ range for zero crossing reversible (bi-polar) units.

We manufacture a large number of special versions of these units and would be pleased to discuss your application with you.

cruusThe HPR Series is now UL recognised (E254121): HP001R, HP2.5R, HP005R, HP010R.
