Smart soft starter UG 9411

asynchronous motorsemiconductorelectronic

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. Features • According to IEC/EN 60947-4-2 • 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 Advantages • Up to 6 functions in one device - Reversing anticlockwise, - Reversing clockwise - Softstart - Softstop - Motor protection - Phase failure monitoring • Widely used measuring and automation protocol • 80 % less space • Simple and time-saving commissioning as well as user-friendly • Operation through parameterization via modbus • Hybrid relay combines benefits of relay technology with non-wearing semiconductor technology • High availablility by - Temperature monitoring of semiconductors - High withstand voltage up to 1500 V - Load free relay reversing function - Device overload • Pluggable clamps • TWIN- connection terminals to loop auxiliary supply and Bus
