FLOATING GROUND
POWER SUPPLY
for Time-Of-Flight Mass Spectrometry detector
High Voltage Power Supply
- Floating Voltage:
±20kV to ±30kV - Rated output voltage:
4kV
4kV Output, Maximum 30kV Floating Ground
The MF series is a floating ground high voltage power supply designed for detectors such as Microchannel Plates (MCP), Electron Multipliers (EM), and Channel Electron Multipliers (CEM) commonly used in mass spectrometers, including Time-of-Flight Mass Spectrometry (TOF-MS) systems.
The floating power supply can be isolated from the ground by up to 30 kV.
FAQ: What is floating ground?
