The Power Control Unit PCU16 is a compact, standalone microprocessor device for controlling UHV vacuum system.

It supports one ultra-high vacuum pump (e.g. turbo molecular pump, ion pump, cryo pump, etc.), electromagnetic vent valve, electromagnetic safety valve, fore vacuum pump and two vacuum gauges based on the 0 - 10V output standard. The PCU16 displays the state of all of the connected peripheral devices on a large 7″ TFT LCD touchscreen, providing clear readouts of important system parameters to the user. The unit comprises several interlocks to protect the vacuum system in the event of power loss or in the case that a pump or other device might fail. Five different and most popular configurations are implemented on the delivered unit. Customers can choose one of these fixed configurations and set it as the default display. Easy firmware upgrade via USB. 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.


  • Control of any high and ultra high vacuum system
  • Measurement of pressure
  • Bakeable and non-bakeable systems
  • Control and automation of pump down cycle
  • Control and automation of venting cycle

The PCU16 has an externally attached UPS ensuring full control and protection of the vacuum system even on power failure. It is available with full dedicated software application or library module.

Additional information

The PCU16 front control panel is divided into two parts:
• left - graphical presentation of vacuum system
• right - panel which indicates the current state of the vacuum system (set-points, power, failures etc.)
