High Voltage Power Supplies

MSS Series

General-Purpose, Unipolar Mass Spectrometry Power Supplies

MSS series modules are designed for single polarity, lower resolution mass spectrometer applications, such as sample ionization chambers, low-resolution quadrupole mass filters, and ion detectors.

  • Max Output Power/Voltage: 5 W/5 to 20 kV, depending on model
  • Ripple: < 200 ppm (1-4 Vpp)
  • Control Interface: Analog or digital
  • Temperature coefficient: 300 ppm/°C
  • Overview
  • Technical Specs
  • Service & Support


Advanced Energy’s compact, general-purpose MSS series modules are ideal for applications that require a small footprint and dependable operation. The MSS series performs reliably under short-circuit or arc conditions. The modular design enables an array of performance features and combinations, such as cable length and connector types.


  • Save valuable space with a streamlined design specifically suited for use in mass spectrometers
  • Access the high reliability and performance you need for precision mass spectrometry
  • Decrease cost with flexible output options; select only needed high voltage capabilities
  • Enable reliable performance under short-circuit or arc conditions


  • Compact modular design, available with either positive or negative output polarity
  • Set by internal potentiometer, external voltage, or external potentiometer
  • Efficient and reliable operation
  • Choice of three different models; customer-defined derivatives upon request
