Varian Turbo-V 70 Pump Controller
Agilent Varian Turbo-V 70 Turbomolecular Vacuum Pump Controller
The controller is a solid-state frequency converter which is driven by a single chip microcomputer and is composed of:
- Power transformer
- Front panel display and keyboard
- Rear panel with input/output connectors
- 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.
