INDUCTION MOTOR SOLID-STATE REDUCED VOLTAGE STARTER
(SOFTSTARTER) WITH SOFTSTOP FEATURE
The Series EMC can be used as an alternative to costly and relatively big variable
speed controllers in applications such as pumps, fans, compressors and
conveyors.
Its six-thyristor structure, working like a full-wave phase angle controller (both
positive and negative cycles are controlled), reduces the induction motor starting
current as well as the motor starting torque. The reduction in motor starting
current improves the efficiency of the power used. It also avoids voltage
fluctuations that lead to ambient light variations or “flicker.”
The Series EMC fits existing applications without any modification of the wiring
field configuration. Thus it can replace an electromechanical star-delta starter
without changing the motor coupling. The EMC may be implemented like a
standard three-phase electromechanical contactor for induction motors.
Furthermore, its ability to be installed inside the delta wiring allows the Series
EMC to drive 1.73 times more current than a standard online softstarter.
The Series EMC features diagnostic and self-test functions to assist with machine
maintenance, reduce costs, and delays of restarting equipment.
