High-Performance High-Voltage Power Supply Thoroughly Pursuing "Smallest" and "Low Noise"
The HJPSS series is a benchtop size, high-performance, high-voltage power supply that combines space-saving and superior performance. Despite its compact width of 4.13-inch(105 mm), it can output high voltages of up to 5 kV with low noise. In addition, simple operation and extensive protection circuits make it easy and safe to use. Moreover, a LAN interface is included as standard equipment, making it easy to integrate into the system. It can be used for many applications, from high-precision applications such as Photomultiplier Tubes (PMTs) to small experiments at schools.
FEATURES
- Low ripple of 5 mVp-p minimum (output models below 2 kV), high stability and excellent temperature coefficient.
- Safe and easy operation with a simple configuration consisting of only an output voltage setting knob and OUTPUT switch and various protection functions.
- Optimal model can be selected from a wide variety of models (45 models in all) according to the application.
- Bipolarity output type can easily switch polarity from the front panel or remote control connector.
MAIN APPLICATIONS
- Photomultiplier Tube (PMT)
- Bias power supply
- Various high-voltage tests
- Microchannel Plate (MCP)
- Electrostatic test
- Radiation detectors
- Dielectric withstand test
