PRECISION HIGH VOLTAGE
The CFP Model 2011 High Voltage Power Supply is a single-width NIM module designed primarily for use with photomultiplier and electron multiplier tubes. But it can be used with any detector requiring a bias voltage up to 5000 V and a current level of 500μA or less.

Features:

  • Compact single width NIM package
  • Regulated up to ±5000 V dc 500μA output for negative and positive separately
  • Noise and ripple ≤10mV peak to peak
  • Overload and short circuit protected
  • Overload, inhibit status indicators
  • Inhibit and overload latching circuits
  • Analoge front panel meter
  • CFP Instrument Control Bus (optional)
  • LAN, USB, RS485 CFP port available

Description:

The CFP Model 2011 High Voltage Power Supply is a single-width NIM module designed primarily for use with photomultiplier and electron multiplier tubes. But it can be used with any detector requiring a bias voltage up to 5000 V and a current level of 500μA or less. The 2011 allows the user to select from two continuously adjustable outputs, ranging from ±15 to ±5000 V dc. The output voltage is measured and displayed by a analoge voltmeter. In addition, this unit allows the user to has fully separately positive and negative output voltage polarity. The 2011 unit are fully arc and short circuit protected and will limit continuous short circuit output current to less than 150% of maximum rated output current.

 Electrical and Mechanical Power Required:
