MODEL 5003

Unipolar (positive or negative) power supply: 2 kV @ 5/10/20 mA

  • Low output ripple
  • Arc and short circuit proof
  • Positive or negative output
  • Internal and external programming
  • Output voltage metering
  • DC or AC line input models
  • Ideal for photomultiplier tubes

Model 5003 is a modular, unipolar power supply that can output up to 2 kV and 20 mA. Output ripple is less than 5 mV and the output is immune to arcs and short circuits. Local and remote output voltage programming is supported, and an output metering signal is available to allow remote monitoring of the high voltage output. Excellent noise performance and high tolerance of load faults make these supplies ideally suited for applications such as powering photomultiplier tubes.

Two versions of Model 5003 are available, one with line-powered AC input (5003AC) and one with DC power input (5003DC). Model 5003DC can be configured for either positive or negative input voltage polarity.

Model 5003AC

Model 5003DC

Several configuration options are available:

  • Maximum output current may be 5, 10, or 20 mA.
  • Connector types include Alden receptacle, high voltage BNC receptacle, or flying lead.

Please specify all options when ordering. Call CPS for further information regarding customization of Model 5003.
