TURBO-V 300HT PCB CONTROLLER DESCRIPTION

The controller (model 969-94xx) 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 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 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.
