HVS900N

Precise, Stable High-Voltage Power Supply

Precision multi-channel high-voltage power supply delivering exceptional stability and reliability for detector systems and scientific instrumentation.

Overview

The HVS900N is a multi-channel high-voltage power supply designed for applications requiring high stability and reliable operation. Featuring 16 independent output channels, it provides two selectable voltage levels (–830 V and –950 V) with output currents up to 20 mA per channel.

Designed for scientific and industrial environments, the HVS900N combines precise voltage regulation, low temperature coefficient, and integrated communication and interlock interfaces in a standard 19″ / 3U rack-mount format, making it ideal for detector systems, automated test equipment, and large-scale experimental installations.

The HVS900N is used in the TILECAL hadronic calorimeter of the ATLAS detector, demonstrating its suitability for demanding high-energy physics applications.
