HIGH VOLTAGE POWER SUPPLIES
for Photomultiplier Tubes (PMT)
- Voltage range: 0.35 to 2 kVdc
- Current: 2.5 to 14 mA
- Max Power: 5 W
- High stability 0.01%/h
5 W High Power Output in a Compact Design
The TD series provides a high power output of 5 W in a compact PCB-mount (on-board) form factor. This high current capacity helps maintain signal linearity in Photomultiplier Tubes (PMT), particularly during high-count-rate operations or when handling large signal pulses. The robust power design is also suitable for driving multiple PMTs in parallel. Additionally, the TD series features low ripple and minimized radiation noise, which significantly improves the signal-to-noise ratio (S/N) of sensitive measurement systems.
FEATURES AND BENEFITS
- High power output (5 W) ideal for PMT applications
- Compact PCB-mount design for easy integration
- High stability (0.01%/h) and low temperature coefficient (0.01%/°C)
- Low ripple noise: 30 mVp-p (0.35 kV model)
- Extended reliability: Design minimizes use of aluminum electrolytic capacitors
- Complete protection circuits, including continuous output short-circuit protection
- Metal shielding to reduce radiation noise
APPLICATIONS
- Gas Chromatography
- Geiger Muller Tube (GM Tube)
- Microchannel Plate (MCP)/Image Intensifier (I.I.)
- Nuclear Instruments
