UV Source Power Supply UV40A-PS


The UV40A-PS can work in either constant discharge current or discharge voltage mode to provide the best operation conditions for the UV source. The source can be automatically ignited directly from the power supply or manually on the source via a piezo-electric igniter. All adjustable parameters are clearly displayed on the large front-panel TFT and precisely controlled via digital encoders. The unit also features a built in timer and automatic standby mode. The UV40A-PS can be supplied as a full width 19″ rack mounting unit (3U height). Easy firmware update via USB port. Unit can be remotely controlled via RS232/485 or Ethernet interfaces.


The UV40A-PS power supply controls the UV40A1 UV Source in ultraviolet photoelectron spectroscopy (UPS) applications. It allows efficient and accurate control of the He I / He II ratio via precise adjustment of helium pressure and discharge current.
