high-voltage-supply HMM
  • HMM series in very small compact box
  • Precision high voltages up to 10 kV at max. 9 W
  • Polarity positive or negative, factory fixed
  • Stable output voltage
  • Low ripple and noise
  • Very low EMI
  • Patented resonance converter technology
  • Internal reference voltage
  • High voltage output by HV connector or HV cable
  • INHIBIT input
  • Remote control and monitoring of V and I
  • Modified versions on request

The HMM series includes high voltage power supply modules with output voltages up to 10 kV in a very compact and easily mountable housing.
The maximum power is 9 W, the polarity is factory fixed. The HV output is finished by a SHV connector (KINGS for 10 kV) or by a HV cable. The supply and control voltages are connected via a D-Sub 9 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 of output voltage and current. The patented resonance converter technology and the metal box shielding guarantee lowest EMI.

*1 - Specify HV output variant: "R" for SHV or KINGS connector, "W" for HV cable,
eg. HMM-0.5P15-24-R

The standard output implementation for 0.5kV – 6kV units is a SHV connector, the 8kV and 10kV units are equipped with a shielded HV cable. Other versions are available on request; minimum order quantity may apply.
