Hybrid motor starters extend motor life and save space

Expanding on its extensive product line for motion control applications, Sensata Technologies has launched the Crydom DRMS Series hybrid motor starters. These hybrid starters 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 4kW. 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. Other performance characteristics include forward/reverse, adjustable settings for starting/deceleration torque, starting/deceleration ramp, nominal motor current and a convenient reset button on the front of the unit for external manual reset. 

The compact 22mm wide DIN Rail mount motor starter package features an output rating of 9Amps at 480VAC, 24VDC control voltage and four easy-to-see LED status indicators.

Complementing Sensata’s existing DIN Rail solid state contactors with more functions and similar ratings, the DMRS Series provides customers with a broader range of solutions for motion control.
