HCH20K0 Series

20kW regulated high voltage AC-DC power supplies with outputs from output voltages 0-650VDC to 0-300kVDC

The HCH20K0 series of high DC output power supplies principle of operation is that 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. Depending on voltage and power the units are configured as single or double 19" racks, or for 35kVDC and above, as an oil filled HV container with the power electronics on the top or in a separate rack.
