TURBO-V 70 CONTROLLER DESCRIPTION

The controller is available in two versions which differ
only in the factory-set input voltage:
•
Model 969-9405 (220 Vac, 50-60 Hz)
•
Model 969-9505 (120 Vac, 50-60 Hz)
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
(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,
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.
