VHQ

High Precision Dual Channel High Voltage Module in VME

The established VHQ dual channel HV module is cased in compact VME standard. VHQ series HV supplies are front panel controllable with a precise 10-turn potentiometer per channel for voltage setting and a common LCD for display of voltage or current. For remote control the VHQ is fully compliant with VMEbus.

The voltage ramp is hardware fixed and can be changed in remote operation. The high voltage output is short circuit and overload protected, an INHIBIT input over external digital signal switches the HV off.


  • LCD for voltage and current display
  • switchable polarity
  • very low ripple and noise
  • front control with precise 10-turn potentiometers
  • hardware voltage and current limits with 10% step
  • VMEbus compliant
  • programmable parameters (current trip, ramp speed,.. )
