TURBO-V 70 CONTROLLER DESCRIPTION

The controller (model 969-9509) is a solid-state
frequency converter which is driven by a single chip
microcomputer and is composed of a PCB which
includes power supply and 3-phase output, analog and
input/output section,
section.
The power supply section detects the input voltage
(from 90 to 265 Vac, 50/60 Hz) and converts it by
means of an high frequency switching circuitry into the
suitable voltages to supply the unit and the 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 EEPROM is used to store pump operating
parameters and
information upon failure.
The controller can be operated via remote signals
through input/output connectors.
The following figure is a picture of the Turbo-V
controller.
