UV40A-PS Power Supply from Prevac

The UV40A-PS power supply, available from Prevac, is designed to control the UV40A1 UV Source in ultraviolet photoelectron spectroscopy applications. It enables precise and efficient control of the He I/He II ratio through accurate adjustment of helium pressure and discharge current.

The UV40A-PS can operate in either constant discharge voltage or discharge current mode to deliver optimum operation conditions for the UV source. The source can be manually ignited through a piezo-electric igniter or automatically ignited directly from the power supply.

The large front-panel LCD displays the adjustable parameters, which are accurately controlled through digital encoders. In addition, the UV40A-PS power supply includes an integrated timer and automatic standby mode. The unit can be supplied as a free standing or full width 19” rack mounting unit (3U height) and can be operated through the intuitive touchscreen interface, computer, or mobile applications.
