YHM Series - Module Type

YAHATA ELECTRIC is a pioneer and top maker of high voltage power supplies for copy machines and laser beam printers. Our High Accuracy DC Power supply is the result of many years of accumulated research, development and production.

High Accuracy&High Performance


  • High accuracy, low ripple voltage, high reliability,and protection function for safety.
  • Operation function of constant voltage output. (optional: constant voltage/current output)
  • Output voltage(current) controlled by external resistance or external voltage.
  • Terminal with buffer amplifiers for monitoring output voltage and current.
  • Remote control terminals for ON/OFF
  • Detection of minimum output voltage for abnormal operation.(optional)
  • Shutdown for over output voltage.
  • LED indicators showing voltage output.
  • Energy suppression built-in circuit for high voltage discharge.
