30W High Voltage Power Supplies

The EPM series of high voltage power supplies provides very well regulated, low ripple high voltage in a highly efficient, compact design. 

The output voltage and current are controllable over the full range of operation. Voltage and current program­ming and monitoring signals are all 0-10Vdc where corresponds to 0 to 100% rated output. A High Voltage Inhibit/Enable signal allows for simple on/off control of the power supply.  

Typical applications:

  • Electrophoresis
  • Photomultipliers
  • Electron Beam
  • Laboratory Applications
  • Ion Source
  • Electrospinning
