The Trek® 605A high voltage reference supply provides precise control of output voltages in the range of 0 to +1 kVDC or 0 to -1 kVDC with an output current range of 0 to ±1 mADC. The instrument offers both fixed and variable operating modes. The Trek 605A is protected against over-current conditions that may be generated by output short circuits to ground. In addition, a digital enable feature provides a connection for a remote device to turn on and off the high voltage of the instrument, making it suitable for automated control systems.


  • Gain precise control of output voltages
  • Operate in fixed or variable modes
  • Operate the unit on a benchtop


  • All-solid-state design for accurate, low-noise operation
  • Short-circuit protection for safeguarding equipment
  • Remote high voltage on/off feature for automated or computer-controlled systems

Select specifications are shown below. Please see product data sheet for additional specifications.
