Alpha IV Series

100W Fast Polarity Switching PSU

4607, 4707

Applications: R+D for Mass spectrometers, Nuclear instrumentation, capillary electrophoresis

  • ±10kV, and ±20kV types
  • Fast solid state polarity switching
  • Remote voltage & current programming
  • High Stability, temp-co < 10ppm / ° C.
  • Voltage & current meters
  • Flashover & short circuit protected
This range of high performance 100W high voltage 19” rack mounting power supplies has been specifically designed for applications where a remotely switchable polarity is required. This versatile high voltage power supply employs solid state switching techniques allowing for fast polarity reversal whilst maintaining excellent line and load regulation. These supplies are designed to operate from a standard AC supply (90V to 264) 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 Alpha IV series ideal for use in test and research applications in such fields as mass spectrometry, surface science and nuclear equipment. The output voltage may be controlled from 50V to maximum (10 or 20kV) of either polarity by means of front panel controls or USB interface (if fitted).
