MK Series

Up to 60kV Regulated High Voltage DC Power Supplies

The MK Series of 75 watts high voltage supplies are air insulated, fast response units, with tight regulation and low arc discharge currents


  • Input: 105-125V RMS, 48-420Hz single phase, less than 1.5 amperes 180 VA maximum at full load. C14 input connector per IEC 60320, with mating line cord, provided.
  • Efficiency: Better than 75% at full load
  • Output: Continuous, stable adjustment, from 0 to rated voltage or current by panel mounted 10-turn potentiometer with 0.05% resolution or by external 0 to 10V signals is provided.Voltage accuracy is 01% of setting + 0.5% of rated. Repeatability is < 0.1% of rated


  • Current Regulation Unequalled in a Module of This Price Range. For example, the regulation from short circuit to rated voltage for the 15kV, 5mA model is +2.5 microamperes.
  • “Air Insulated” designs are completely serviceable; this module is not an epoxy block “throw-away.”
  • AC Power “ON” Indicator
    • Local voltage or current control user
    • Remote voltage and/or current control via 0 – +10 volt
    • Remote voltage and/or current control via
    • “Multi-Mode” operation permits maximum user flexibility.
  • Protection: Overload, short circuit, and arc protection is provided by automatic current regulation and by careful surge limiting design.
