Soft Starters

The RSHR midi is a compact easy-to-use ac semiconductor motor controller. With this controller 3-phase motors with nominal currents up to 18a can be soft started and/or soft stopped. The rshr midi controls 2 phases only, one phase is continuously connected to the load. Soft starting and soft stopping is achieved by controlling the motor voltage. During running operation the semiconductors are bypassed by internal electromechanical relays. Starting and stopping time as well as initial torque can be independently adjusted by built-in potentiometers. Leds indicate the status of the controller including an alarm status in case of over temperature in the RSHR. . V21 models. The RSHR midi comes with an integrated heat sink and is ready to mount on din rail.
