Five-Sided Shielding

Brass cases with nickel plating provide five-sided shielding, which contributes to very low output ripple and noise. The low output ripple means less external filtering is required for applications sensitive to EMI (electromagnetic interference).

Applications include:

  • Photomultiplier tubes
  • Detectors and photodiodes
  • Mass spectrometers
  • Ultrasonic probes
  • Electron microscopes.

Programmable Output Voltage

The output can be programmed using an external voltage supply or potentiometer, so remote adjustment is possible. The output can be adjusted from 0.5% to 100% of the rated voltage.

Compact Size

The compact package size of the CHVM package means less board area is needed. Three sizes cover power levels from 1.4 W to 3 W and output voltages of 180 V to 2 kV:

  • CHVM1R5 (1.4 and 1.5 W), measuring 44 x 16 x 30 mm (WxLxH)
  • CHVM2 and CHVM2R6 (2 and 2.6 W), measuring 110 x 12 x 19.75 mm
  • CHVM2R5, CHVM2R7 and CHVM3 (2.5, 2.7 and 3 W), measuring 80 x 12 x 19.75mm.
