Description

The Power Control Unit PCU14 it is the compact, stand alone microprocessor device to control one complete UHV-pumping system. Its including ultrahigh vacuum pump (e. g. turbo molecular pump, ion pump, cryo pump, etc.), electro-magnetic vent valve, electro-magnetic safety valve, fore vacuum pump and vacuum gauges based on 0..10V output standard. As standard all of Oerlikon-Leybold gauges are implemented: ITR100, ITR90, PTR237/9, TTR90 (any other can be implemented as option).
State of all peripheral devices connected to the PCU14 is currently displayed on big LCD graphics display, giving clearly readouts of basic parameters to the user.
Unit comprises several interlocks to protect the vacuum system during power failure or in the case of breakdown of its components.

Application

• Any high and ultra high vacuum system

• Measurement of ultimate pressure
• Bakable and non bakable systems
• Pressure measurements and control from atmosphere to UHV range

Implemented PCU14 software fully controls shutdown and venting process of theUHV-pumping system. Attached external protective battery (UPS) protect controlled system against unexpected power loses.

PCU14 may be equipped with RS485 or 232 / USB serial interface to enable remote control and data collecting eg. vacuum etc.

Mounting

• When the safety valve is
• Located between fore vacuum and turbomolecular pumps
• When the safety valve valve is between turbomolecular pump and the UHV chamber
• Other design of vacuum system
• Current schematic of controlled vacuum system is displayed on graphics LCD.
