OHV Series 1000 V to 2000 V High-Voltage DC/DC Power Supplies

Bellnix’s compact converters with low ripple noise are ideal for photomultiplier applications

Bellnix’s OHV Series 1000 V to 2000 V High-Voltage DC/DC Power Supplies Bellnix’s OHV series high-voltage DC/DC compact converters can reduce the mounting area by about 60% compared to conventional products and have a low ripple noise of 5 mV_P-P that is achieved by their original circuit technology. They are a long-life, high-reliability power supply with a five-sided metal case to provide additional shielding.

The output voltage on the OHV series can be controlled from 0 V to 2000 V by an external voltage or an external variable resistor.

The OHV series of power supplies are ideal for applications where the stability (noise) of the high-voltage power supply affects the accuracy of the equipment. Semiconductor manufacturing equipment and blood analysis equipment are two examples of products that are equipped with photomultipliers. Photomultiplier tubes require low noise and high-voltage because noise from the power supply affects the detection capability of equipment.
