QD600 Digital Soft Starter for motor, is a measuring and controlling circuit with mirocomputer chip-oriented to control motor’s input voltage through controlling the flow angle of thyristor of main circuit to realize decreasing smooth starting of motor which impacts electric net and motor. This new starter can make motor’s starting current to be restricted within three times and is an ideal substitution product of the tradeitional self-coupling reduction voltage starter. It also carry out all-way monitor function for motor’s operating parameters and provides all series protection and parameter measurement to make the users save routine measurement and protect device. In addition, QD600 can meet the communication requirements with other equipments.

Main Starting Mode
��lope voltage starting
��urrent limit starting
Main Stopping Mode
��oft Stopping
��ree Stopping
Main Features
��owering motor's starting current and the capacity of power distribution;decreasing the strike on the electric net;
��elieving the impact of moment when motor starting, and lengthing the life of motor and related mechanical equipment;
��rovideing perfect protection for motor, such as, phase default, overcurrent and overload etc;
��he contactor is of turning on and off without current, thus lengthening life of the contactor;
��roviding the post of external control and state and being convenient for control the device from other places;
��ode display and keyboard operation are convenient for users monitoring data and adjusting parameters;
��eing a structure of multi-box with wall-hanging type and cabinet type, it is convenient for installation;
��nly using three-phase for input and output, wiring is convenient, without needing to control circuit.
