HVPS124

OEM High Voltage Power Supply

HVPS124

The OEM High-Voltage Power Supply is designed to set the bias voltage of various types high-resistance sensors, such as CdZnTe-, 3He- or HPGe detectors, piezo devices, toxin detection and etс.

The HVPS124 module fully regulated and programmable outputs of 0 to 2000 volts are available in positive polarity. They based of micro-power DC to high voltage DC converters feature low EMI/RFI due to a magnetic free design.

Modules are available in two types. Module HVPS124-3V powered from 3.0 V to 5.5 V, module HVPS124-5V powered from 4.5 V to 15 V.

Low power consumption and light weight, with a case height of less than 7 mm, allows the use of a module for portable, battery powered equipment.

Voltage monitoring is provided at a 1000:1 ratio. Soft-start high voltage ramp-rates are designed in to further protect sensitive detectors to support long-term reliability.
