TURBO-V 250 CONTROLLER DESCRIPTION

The controller model 969-9504 is a solid-state
frequency converter which is driven by a single chip
microcomputer and is composed of:
− Power transformer
− Left panel with input/output 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
− PCB external input/output interface.
The following figure is a picture of the Turbo-V
controller.
The power supply and the 3-phase output 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,
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.
The controller can be operated by remote signals via
the left
monitored/reprogrammed using the optional hand held
terminal via the right panel connector.
