high-voltage-supply J4

This model is an ultra low ripple, high voltage power supply, especially developed for photomultipliers. It also can be used as a power supply for radiation detectors such as phototubes, GM tubes and proportional counter tubes.
Remote programming as well as protection against continuous short circuit is integrated. The two series differ from type of input connectors.

Features:

  • Exceptional low ripple and high stability
  • Remote and local programming
  • Fully protected against continuous short circuit
  • Optional output connector
  • UL1950, TÜV, CE approved
