Ultra-compact PCB-mountable high-voltage power supplies for Photomultiplier Tubes
The TF series consists of compact, well-regulated high-voltage power supplies designed for photomultiplier tubes (PMTs). Housed in metal shielding for exceptionally low noise, these modules feature versatile external control options and robust protection against arcing and continuous output short circuits.
FEATURES AND BENEFITS
- Compact footprint, PCB-mountable (SIP format)
- Low ripple and noise (15 mVp-p or 30 mVp-p)
- Metal shielding for superior noise immunity
- Programmable via 50 kΩ potentiometer or 0–5 V control voltage
- Integrated protection against arcing and continuous short circuits
APPLICATIONS
- Gas Chromatography
- Geiger Muller Tube (GM Tube)
- Microchannel Plate (MCP)/Image Intensifier (I.I.)
- Nuclear Instruments
- Photomultiplier Tube (PMT)
- Radiation Detection
