  • Usable for desktop HV PS (THQ series)
  • Integrable in multichannel HV systems (MMC)
  • Polarity electronically switchable
  • Voltage and current limits via potentiometer
  • Patented resonance converter technology
  • Very low ripple and noise
  • Very low EMI
  • Stable output voltage
  • Modified versions on request

The HMD/HED series includes high voltage power supply modules with output voltages up to 6 kV in a compact and easily mountable housing.
The maximum power is 12 W, polarity is switchable. The HV output is finished by HV cable (HMD version only) or by SHV connector. Depending on the version the supply and control voltages are connected either via a D-Sub 9 connector or an H15 connector. An internal reference voltage can be used to control the output voltage with help of an external potentiometer. Analog I/O is provided for remote monitoring and control.
To protect connected loads hardware limits for voltage and current can be defined. The patented resonance mode principle and the metal box shielding guarantee lowest EMI.
