Controller Description; Technical Specification - Varian 869-8933 Manual De Instrucciones

Controller Description

The dedicated controller is a solid-state frequency
converter which is driven by a single chip micro-
computer and is composed of two PCBs which in-
clude power supply and 3-phase output, analog
and input/output section, microprocessor and digi-
tal section.
The power supply, together with the 3-phase out-
put, converts the single phase AC mains supply
into a 3-phase, low voltage, medium frequency
output which is required to power the pump.
The controller can be operated by a remote host
computer via the serial connection. A Windows-
based software is available (optional).
