AC/DC Drive Control
The smart motorstarter UG 9411 can be used for softstart, softstop, reversing and protecting 1 phase asynchronous motors. By measuring the line current a thermal model is used to calculate the motor temperature, and in the case of overtemperature the motor is disconnected. In addition also a thermo switch can be used. The reversing is done via relays. The relays are switched without current flow, this provides long service life.
According to IEC/EN 60 947-4-2; Modbus RTU interface; To reverse 1-phase motors up to 50 ... 180 W or 180 W ... 1.1 kW at 230 V; 1-phase softstart, softstop; 3 potentiometer for setting the Modbus adress and baud rate; 5 LEDs for status indication; Reversing with relays without current, softstart, softstop with thyristor; Galvanic separation between control circuit and power circuit; Width: 22.5 mm
