The DRMS48D91 is a hybrid motor starter designed for controlling 3-phase asynchronous motors, providing forward/reverse operation and integrated overload protection. It operates on a line voltage of 200-480 Vrms and can control motors up to 4 kW at 400 VAC, with a maximum AC53a load current of 7.6 Amps. The device features galvanically separated 10-30 VDC inputs for forward and reverse control and provides electronic motor overload protection (Class 10/10A or Class 5). Its hybrid relay design combines the benefits of electromechanical and semiconductor technology for high reliability and a long service life. This compact, DIN rail mountable unit is ideal for applications such as conveyor systems, door and gate controls, and lifting equipment where reliable reversing and motor protection are required.
