MINIATURE HIGH VOLTAGE POWER SUPPLY
- Voltage range: 1.5kV
- Current: 1mA
- Power: 1.5W
- Wide range of output voltage
Compact PCB-mountable high-voltage power supplies for photomultiplier tubes
TFQ series, a compact PCB mountable power supply module, provides extremely low ripple 3 mVp-p at 1.5kV output.
The miniature high voltage power supply featuring a low profile design and ultra-low noise is best for Photomultiplier Tubes (PMTs), Microchannel Plates (MCPs), etc.
FEATURES AND BENEFITS
- Ultra low profile design, PCB mountable
- Low ripple, 3mVp-p
- Wide range of output voltage (continuous and variable output from 0 V)
- Output voltage control by external potentiometer or external voltage
- Enhanced protection circuit (continuous short-circuit is possible)
APPLICATIONS
- Photomultiplier Tube (PMT)
- Geiger Muller Tube (GM Tube)
- Microchannel Plate (MCP)/Image Intensifier (I.I.)
- Nuclear Instruments
- Flat Panel Detector (FPD)
