MCP Model | High Voltage DC DC Converter

Spellman’s MCP Module is a well-regulated, high perfor­mance and high voltage DC DC converter featuring a floating 3kV output, isolated to 16kV. The MCP low output ripple specification makes it ideal for use with detectors in Mass Spectrometry applications like: Electron Multipliers (EM’s), Microchannel Plates Detectors (MCP’s) and Channel Electron Multipliers.

This +3kV @ 330uA high voltage DC DC converter module is packaged in a shielded metal enclosure. The unit has remote voltage programming and a voltage monitor, and features low injected ripple when used with biasing supplies. The MCP module is easily customized to meet OEM requirements with improved ripple performance, improved stability and configurable output lead terminations as required.

Typical high voltage power DC DC converter applications:

  • Mass Spectrometry Detectors
  • Microchannel Plates
  • Electron Multipliers
  • Channel Electron Multipliers
