Agilent / Varian V250 CU Turbo Pump Controller, 9699425S004

Overview:

The Agilent / Varian V250 CU Turbo Pump Controller has the right panel with pump connector and hond held terminal connector, and the left panel with input/output connector, mains socket, forepump and vent coil outpur and fan connector.

The controller is a solid state frequency converter which is driven by a single chip microcomputer.

The controller is composed of:

• Power Transformer
• PCB including: power supply and 3-phase output, analog and input/output section, microprocessor and digital section, display and keyboard circuits.

The power supply converts the single phase (50-60 Hz) AC mains supply into a 3-phase, low voltage, medium frequency output which is required to power the Turbo-V pump.

The microcomputer generates the variable output frequency and controls the 3-phase output voltage according to the software and the gas load condition of the pump.

Moreover, it manages signals from sensors, input/output connection information to be displayed, and gives outputs for a fully automatic operation.

A dedicated non-volatile RAM is used to store pump operating parameters and the input/output programmed information upon failure for a period of 10 years accumulated off time.
