HVLAB3000 Bench-top HV Supply


The HVLAB3000 is a programmable 3000V high stability, dc power supply designed for use with photomultipliers in laboratory and general research applications. It is can also be used in other applications where a similar specification power supply is required.

The output voltage can be set using three different methods:manually, using a ten-turn precision front-mounted potentiometer, digitally via a USB port, or using an analogue control input. The USB control option is available as part of the standard HVLAB3000 software for the unit and is compatible with the ET Enterprises MCS-CT3 multi-channel scaler when used in photomultiplier photon counting systems. The software also allows two HVLAB3000 supplies to be controlled from one application.  

  • HV range 100-3000V at up to 3mA (9W)
  • USB 2.0 interface
  • analogue or digital voltage control
  • user selectable HV polarity
  • small footprint
  • overload protected

Software and User Manual

The MCS-CT3 software is required for USB mode operation but not for analogue voltage control.
