Introduction
The Intelligent Technology (IT) Soft Starter is an electronic,
self-contained, panel or enclosure mounted motor soft-
starting device. It is intended to provide 3-phase induction
motors with a smooth start, both mechanically and elec-
trically. The IT line of soft starters utilizes six thyristors
connected in a full wave power bridge. The voltage and
current applied to the motor is controlled by varying the
thyristor conduction period. This, in turn, controls the
torque supplied by the motor. After the motor reaches
speed, single phase bypass contactors are energized to
bypass the thyristors.
The Intelligent Technology (IT) Soft Starter is designed
to fulfill the industrial service requirements for applications
such as chiller starters, pump panels, and machine tools.
The Intelligent Technology (IT) Soft Starter meets all
relevant specifications set forth by ICS-1, ICS-2, ICS-5,
UL508, IEC 60947-4-2, CE, and CSA.
