2.2.2 TYPICAL SYSTEM CONFIGURATIONS
Phase Perfect
is designed to simplify installations, to provide maximum
versatility, and to eliminate or minimize the need for external electrical
components and related costs. The output of Phase Perfect
is sinusoidal with
virtually no harmonic components, eliminating the need for output filtering that
would often be required for a variable frequency drive (VFD). With virtually no
harmonics on the input, Phase Perfect
does not require input filtering. With the
Motor Starter option, Phase Perfect
can start and protect a single-motor load,
eliminating the need for a three-phase starter panel in many single-motor
applications. A motor starter is not required at the input to Phase Perfect
, as
would be required for a rotary phase converter. All types of equipment, including
inductive, resistive, and capacitive loads can be safely powered by Phase
Perfect
.
Three typical Phase Perfect
installations are diagrammed and explained below:
(1) a motor starter configuration for use with a single-motor load, (2) a pump
configuration in which a pressure or level switch automatically controls power to
the pump, and (3) a power supply configuration for use in powering multiple
three-phase loads.
2.2.2.1
MOTOR STARTER CONFIGURATION
With the Motor Starter option, Phase Perfect
can be used to start and protect
single-motor loads, eliminating the need for a three-phase starter panel. An
appropriate sized fusible disconnect must be installed on the input side of Phase
Perfect
. The optional overload relay can be adjusted for motor ratings up to the
rated HP capacity of the converter.
The motor starter configuration used to
power a single motor is illustrated below:
