Varian Turbo V 70 Turbo Pump Controller, Power Supply, 120 V, 9699507S003

The Varian Turbo V 70 is a turbo pump controller, factory set for 120 Vac and 50/60 Hz input voltage. It is a solid state frequency converter which is driven by a single chip microcomputer.

The controller is composed of:

• Power transformer
• Left panel with input/output connector, mains socket, forepump and vent coil output, fan connector
• Right panel with pump connector and hand-held terminal connector
• 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 on the hand-held terminal, 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. The controller can be operated by remote signals via the left panel connector and may be monitored/reprogrammed using the optional hand-held terminal via the right panel connector.
