These slim hybrid motor starters extends motor life
The Crydom DRMS Series hybrid motor starters (photo) integrate the benefits of both solid-state and electromechanical-relay technologies to produce a compact device that can control electrical power delivery to motors as large as 4 kW. Suitable applications range from access control, packaging equipment, lifts and escalators to industrial process control and machine tooling systems. Unlike many motor starters of similar size, the DRMS Series offers features such as soft start, soft stop and an internal-mains disconnect relay in case of a fault. The starter’s soft start/soft stop function allows for the gradual increase or decrease of power control, thereby extending motor life. Built-in overload protection eliminates the extra cost and space otherwise needed for an additional overload relay. The compact 22-mm wide DIN rail-mount motor starter package features an output rating of 9 A at 480 V a.c., 24 V d.c. control voltage and four easy-to-see LED status indicators. — Sensata Technologies, Inc., Attleboro, Mass.
