Four induction motor softstarters for industrial applications

7 May 2003 Analogue, Mixed Signal, LSI Products & Solutions

Teledyne Relays is offering four, three-phase induction motor softstarters that can be used as alternatives to costly and relatively large variable speed controllers. The solid-state EMC series softstarters are designed for applications such as conveyors, elevators, escalators, pumps, compressors, lamps, fans, cranes and three-phase motor applications.

The EMC softstarters prevent motors from experiencing the stress of high inrush currents - typically six to nine times nominal values - that can cause costly electrical and mechanical damage to the motors and machinery. They feature a six-thyristor structure that works like a full-wave phase angle controller (both positive and negative cycles are controlled), reducing the induction motor starting current as well as the motor starting torque.

The four Teledyne devices offer numerous user settings. Initial torque can be set from 0 to 100 percent. A bypass option is available, as is a PNP or NPN control option. Users also can select a kick option of 0 to 100 ms when choosing not to perform a soft start. The EMC softstarters include a soft-stop capability that allows motors to switch off slowly, reducing the possibility of damage, and this duration can be set manually up to 64 seconds.

Each unit can be mounted on a DIN rail or attached with screws. They include EMC48S50-01 for 200 to 480 V a.c., 2,2 kW (star) and 3,8 kW (delta); EMC48S50-02 for 200 to 480 V a.c., 7,5 kW (star) and 13 kW (delta); EMC48S50-03 for 200 to 480 V a.c., 11 kW (star) and 19 kW (delta); EMC48S50-04 for 200 to 480 V a.c., 15 kW (star) and 26 kW (delta).
