Floating High-Voltage
Power Supply
Designed for Time-of-Flight Mass Spectrometry (TOF-MS) Detectors
- Floating Voltage:
±20 kV to ±30 kV - Rated output voltage:
4 kV
4 kV Output, Floating Isolation up to 30 kV
The MF series is a floating high-voltage power supply engineered for detectors such as Microchannel Plates (MCP), Electron Multipliers (EM), and Channel Electron Multipliers (CEM). It is ideal for mass spectrometry applications, including Time-of-Flight Mass Spectrometry (TOF-MS) systems.
The series features high-voltage isolation, allowing operation at floating potentials of up to 30 kV relative to ground.
FEATURES AND BENEFITS
- Supports floating operation up to ±30 kV
- Ideal for Time-of-Flight Mass Spectrometer (TOF-MS) floating detectors: Microchannel plate (MCP), Electron Multiplier (EM), Channel Electron Multiplier (CEM)
- Low ripple, High stability
- Output voltage adjustable via external control voltage (0 to 10 Vdc)
APPLICATIONS
- Photomultiplier Tubes (PMT), Microchannel Plates (MCP), Radiation Detection
- Electron beam/Ion beam
- Mass Spectrometry (MS) for accelerator
- Electrostatic chuck (E-chuck, ESC)
- High voltage test
Models
| Model | Rated output voltage | Output Current | Maximum floating voltage | Ripple |
|---|---|---|---|---|
| MF-4PN1-20 | 0 to 4 kV | 1 mA | 0 to +20 kV/-20 kV | 100 mVp-p *1 |
| MF-4PN1-30 | 0 to 4 kV | 1 mA | 0 to +30 kV/-30 kV | 150 mVp-p *2 |
