Medium Voltage Power Supplies
Series MYN from 650V to 2kV / 21kW to 50kW

A transformer is used to transform the mains supply to high voltage. Either on the primary side or on the secondary side of this transformer a phase controlled thyristor rectifier circuit is fitted. A series LC filter is used to smooth the resulting rectified voltage.


  • Simple construction
  • extremely robust
  • high efficiency
  • short circuit proof and unlimited operation with full current in short circuit condition
  • voltage and current setting with 10-turn potentiometers with precision scale; the adjusting knob can be locked

Series MCP from 125V to 2kV / 35W to 15kW

In principle, the rectified line voltage drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated. A low residual ripple of the output voltage, together with a high stability, high regulation speed and a low stored energy are all achieved by virtue of the high switching frequency.


  • compact size and light weight
  • efficiency approx. 90%
  • short-circuit and flashover proof
  • unlimited operation with rated current in a short-circuit condition
  • vunlimited operation with rated power
  • 4½ digit DVM''s for voltage and current for all models
