Smart Motorstarter, UG9410

Type:  AC/DC Drive Control
Description:  The smart motorstarter UG 9410 can be used for softstart, softstop, reversing and protecting 3 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.
Connectivity:  Modbus RTU
Features:  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 potentiometers for setting the Modbus address 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
Specifications:  Widely used measuring and automation protocol; Up to 7 functions in one device : Reversing anticlockwise, Reversing clockwise, Softstart, Softstop, Motor protection, Phase sequence monitoring, Phase failure monitoring; 80% less space; Simple, time-saving, user-friendly commissioning; Operation through parameterization via Modbus; Blocking protection; 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
