3590 Series

3590 Series

5W Miniature High Voltage Modules

Applications: Mass spectrometers, nuclear instrumentation, ion pump, CRT, image intensifier

  • 2.5kV, 5kV 7.5kV and 10kV versions
  • Positive and negative polarity options
  • Remote voltage programming or potentiometer setting
  • Voltage monitor & current monitor included
  • Encapsulated in screened metal case for reduced EMI
  • Flashover & short circuit protected
  • UL approved and CE marked

This range of high performance 5W high voltage power supplies has been specifically designed for applications where space is at a premium. These compact DC to DC converter modules operate from a dc supply of either 12V or 24V (nominal) and provide an accurately controlled high voltage output. The use of high stability components within the feedback system ensures a low temperature coefficient and good long & short term drift making the 3590 series ideal for use in many low power and portable applications. The output voltage may be controlled from 50V to maximum (2.5, 5, 7.5 or 10kV) by means of an external control voltage of 0 to +5V (or +10V to special order). Monitoring of output voltage and current are also provided as are fixed and variable references.
