Compact High-Voltage Power Supply Modules (Proportional Type)
- Output:0.3 kV to 6 kV/3 W
- Input:1.5 Vdc to 12 Vdc
- Low ripple
- Small size
HIGH PERFORMANCE, HIGH VOLTAGE DC-DC CONVERTER
The Matsusada Precision UR series is a line of compact, PCB-mountable high-voltage power supply modules. The output voltage is directly proportional to the input voltage, simplifying control integration. Featuring a fully floating output, these modules can be configured for either positive or negative polarity. The UR series delivers stable output voltages ranging from 100 V to 6 kV with ultra-low ripple and noise, making it an ideal choice for precision equipment such as photomultiplier tubes (PMTs), electron microscopes, and electrostatic chucks.
FEATURES AND BENEFITS
- Compact Design: Optimized for PCB mounting
- High Performance: Low ripple and noise for sensitive applications
- Proportional Control: Output voltage scales linearly with input
- Fully Isolated: Floating output allows flexible polarity configuration
APPLICATIONS
- Photomultiplier Tubes (PMTs)
- Ionization Chambers
- High-Voltage Bias Sources
- Electrostatic Chucks (E-Chucks / ESCs)
Models
Unless otherwise noted, specifications apply at maximum rated output after a warm-up period, covering an output range of 10% to 100%.
