- Single Inline Package (SIP) high voltage power supply
- Low ripple, 15mVp-p or 30mVp-p
- Low noise with metal shielding
- Well-regulated, high performance
- Programmable via 50KΩ potentiometer or 0–5 V control voltage
- Arc protection and continuous short-circuit protection
APPLICATIONS
- Gas Chromatography
- Geiger Muller Tube (GM Tube)
- Microchannel Plate (MCP)/Image Intensifier (I.I.)
- Nuclear Instruments
- Photomultiplier Tube (PMT)
- Radiation Detection
