KS Series

General Purpose High Voltage Modules

KS005P, KS0055N, KS010P, KS010N, KS020P, KS020N, KS030P & KS030N

Applications: Monitor CRT, Lens voltages, Focus and high voltage bias, Ion pumps, Image intensifiers

  • 5kV, 10kV, 20kV & 30kV
  • High frequency switch mode
  • Internal control or externally programmable
  • Short circuit and flashover proof
  • 24 hour burn in
  • General purpose

These stabilised miniature power supplies are available in either positive or negative polarity at output voltages of 5kV, 10kV, 20kV and 30kV. They are intended for cathode ray tube and general purpose applications and the output voltage can be controlled by internal or external potentiometers or by and external 10 volt analogue control voltage. The units are pin compatible with the high precision HP series and the 100Watt HW series of power supplies.

All units are short circuit proof and use high frequency switching techniques, in conjunction with a ferrite step-up transformer to control the output. All high voltage components are vacuum encapsultaed in silicon rubber.

Please contact us to discuss special versions of these units.

cruusThe KS Series is now UL recognised (E254121).
