Motor Controllers AC Semiconductor Motor Controller Type RSHR MIDI * Soft starting and stopping of 3-phase induction squirrel cage motors * 2-phase control with integral bypassing of semiconductors * Low inrush and reduced vibration during starting * Rated operational voltage: up to 600 VAC, 50/60Hz * Rated operational current: up to 18A AC-53b * Multivoltage option with a range of 190 - 530 VAC* * LED status indicators * Optional device over-temperature protection * Optional auxiliary relay for end of ramp * DIN rail mounting * requires external supply Product Description 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 continously connected to the load. Soft starting and soft stopping is achieved by controlling the motor voltage. During running operation the semiconductors Ordering Key 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 overtemperature in the RSHR...V21 models. The RSHR Midi comes with an integrated heatsink and is ready to mount on DIN rail.

Therefore the semiconductors can only be damaged by short-circuit currents during ramp-up and ramp-down. Please note that the motor controller does not isolate the motor from the mains. Figure 1: Protection of the device when using fuses. Protection with semiconductor fuses is intended to protect the motor feeder and motor controller from damage due to short-circuit. Figure 2: Protection using a thermal-magnetic motor protection relay. The motor feeder is protected but damage to the motor controller is possible. When motor failure occurs, if part of the motor winding limits the fault current and the motor feeder is protected, this type of protection can be considered acceptable. Figure 3: Secondary conductors. 3.1: Control using a 2-position switch. When K is closed, the control input is supplied to A1, A2 or A3 and soft starting of the motor is performed. When K is opened, soft stopping is performed. 3.2: Auxiliary Relay (For RSHR...BV21 models) The End of Ramp relay 11, 12 (NO) can be used in series with the supply to the coil of an external bypass contactor. Figure 4: Control using ON and OFF push buttons Pushing S1 soft starts the RSHR. Pushing S2 soft stops the RSHR. K is an auxiliary contact of the mains contactor. Figure 5: Control using 2 phases Connecting input A1, A3 to two of the incomming lines will soft start the motor when K is operated. When K is switched off, the motor will stop (no soft stop). This configuration does not apply to the RSHR60.... versions. Figure 6: Control when using operational voltage greater than 480V Connecting A1 to Neutral and A3 to one of the incoming phases (or vice-versa) will soft start the motor when K is closed.
