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.

Options

-LGob

Optical interface port * Standard LAN port is not provided when -LGob option is selected.
This option changes the standard interfaces to built-in optical interface port. By combining this option with an adapter for optical connection (sold separately), communication between the control device and the power supply can be controlled in an isolated state.

  • -LGob: Optical interface port + optical cable 2 meters
  • -LGob(Fc5): Optical interface port + optical cable 5 meters
  • -LGob(Fc10): Optical interface port + optical cable 10 meters
  • -LGob(Fc20): Optical interface port + optical cable 20 meters
  • -LGob(Fc40): Optical interface port + optical cable 40 meters

Select the optional optical interface port (-LGob) when using this DC power supply under the following conditions.

  • Noisy environments such as factories (example: when motors or coils are used near loads or power sources).
  • If this power supply and your controller (PC or PLC) cannot be installed within 2 meters.
  • When there is a possibility of arcing or output short-circuit.

The length of shielded high voltage output cable is changed to 3-meters.
(If you require a length other than this, please contact our sales representative.)

-L(5m)

The length of shielded high voltage output cable is changed to 5-meters.
(If you require a length other than this, please contact our sales representative.)

-L(7m)
