Auto-Reversing High Voltage Power Supply

Spellman’s CZE1000R is a full feature rack mountable high voltage power supply ideal for laboratory usage. It’s designed to meet the needs of applications requiring a hot switched reversible output voltage. The output polarity can be quickly and safely reversed via a front panel switch.

Both the output voltage and current are fully adjustable from 0 to 30kV and 0 to 300uA via front panel ten turn locking counting dials. Remote control operation is done by 0 to +10Vdc programming signals; either user generat­ed or using the provided +10 Vdc reference and external potentiometers.

Front panel voltage and current meters provide local monitoring. Voltage and current test points are provided such that 0 to 10Vdc corresponds to 0 to 100% rated output. A two position, normally closed, external interlock is provided for protection of external high voltage accessi­ble areas. If the interlock is opened the high voltage will shut off and fall to zero in less than one second and not be able to be re-energized until the interlock is closed.

Excellent load and line regulation specifications along with outstanding stability and low ripple of the CZE1000R assure a stable high voltage output for consistent process results.

Typical applications:

  • Electrospinning
  • Mass Spectrometry
  • Capillary Electrophoresis
  • Electrostatic Research
