Quad VME Power Distributor


  • 1-unit wide VME 6U module
  • Four DB9 connectors with ±6 V, ±12 V, ±24 V each
  • Ripple: <1mVpp on ±6 V; <2mVpp on ±12 V, ±24 V
  • Survey of all 6 voltages on each output
  • Protection of all voltages by self-recovering electronical fuses
  • Individually filtered outputs to ensure low noise operation
  • Standard voltage output compatible with CAEN electronics and with many other manufacturers


The V5425 is a 4-channel VME power distribution module.

The individual voltage outputs (±6 V, ±12 V and ±24 V) are protected by electronic fuses which automatically recover after short circuit. All six voltages are surveyed for each of the four outputs. The status is displayed by LEDs.

Low-noise preamplifers require DC power that is free of interference generated by other modules inserted in the VME crate. The mod. V5425 ensures this low-noise capability by filtering the power lines separately at each connector.
