Rack mount type
High voltage power supply

Ultra high voltage of 200kV model is now available!

Ultra high voltage models of 150kV to 200kV debuts at 19-inch size!

AUH series is high performance High Voltage power supplies which can output ultra high voltage of maximum 200 kV in the 19-inch rack size. By the safety design without the exposure of the high voltage output part, quantity of outbreak of the corona is held down as compared with the open type power supply.

Therefore, the large space reservation for prevention of electric shock becomes needless and enables setting in the space-saving. In addition, by various remote control functions and a full protection function, AUH has high reliability and usability.

Main features

  • Ultra high voltage of 200kV and high power of 2kW.
  • AUH is largely miniaturized by having made the high voltage output part into the seal structure by potting.
  • The high reliable design that is hard to be affected by the use environment.

-LF: Floating ground (Isolation voltage: 50 Vdc)

t is used when measuring the very small current which flows into load.

(This option is not usable in a use to let a high voltage power supply make floating.)

-LLr *1: Lower ripple

Ripple becomes 0.1%p-p.

-LMs *2: Master slave control

Maximum of four slave units can be controlled with one master unit.

-LOc *2: Cut off when over current

-LW: Slow start

Takes about 10-second to reach maximum rating voltage from when OUTPUT switch or remote switch is turned on.

-L(200V3P) *1: Three-phase input

  1. -LLr option and -L(200V3P) option cannot be selected together. Only one of each can be selected.
  2. When simultaneously equipped with the -LMs option and the -LOc option, please consult to us.
