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 is 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. Autosave function for saving your parameters/unit preset and applying them automatically after restart.
