YCQR2 soft starter integrate of the latest theories of motor control,motor protection technology,power electronics technology and modern computer technology, advanced computer processors as the core, high-power thytistor control components,to achieve current startup, voltage slope start and soft-stop functions. The parameters can be set in accordance with the load and has over-current,overload, missing phase and other multi protection. The output voltage of soft starter raise according set regulation,drive the controlled motor finish the start process according to optimized accelerate curve,off the thyristor and worked by the bypass AC contactor. It successfully solve the problem of poor electricity quality, increasing of power loss,machinery equipment impulse because of big starting current when the AC motor starts.
The YCQR2 soft starter cover 5.5~500kW squirrel-cage three phase asynchronous motor.Widely used in metallurgical, chemical,construction,cement,mining,environmental protection,and all industrial sectors of electrical transmission equipment,is the ideal replacement product of traditional triangular starter,reactor starter,auto decompression starter.
