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 include power supply and 3-phase output, analog and
input/output section, microprocessor and digital section.
The power supply, together with the 3-phase out-put, converts the
single phase AC mains supply into a 3-phase output which is
required to power the pump.
The controller can be operated in two ways:
via digital/analog I/O connector
via serial RS 232 or 485 connector.
