GD2-100 Series double power automatic transfer switch(shift switch) is one of the products that is developed by our company with the international latest ATS technology. The switch and the matched intelligent display are mainly used where uninterrupted power supply is needed, such as high-rise buildings, post and communication, coal mines, ships, military facilities and industrial assembly lines. Under the inevitable trend of rapid increase of power consumption in cities, it can satisfy the higher requirement of power reliability better,and it has the characteristics of reliable performances, small size and simple operation. With reliable and safe interlock It has reliable connection and disconnection main circuit and second circuit function and the setting has self-locking function. It has safety insulation isolate Quick transfer speed,( the transfer time is 0.1s~0.2s ), low malfunction, and reliable capability. Ismall in volume, simple in constitution, large current an ATSE integrate. With the controller, the setting can transfer between the manual and automatic,and has the every protection function. Imake sure the facility safe, it has neutral pole N input first and breaker later function, which can avoid of the abnormal voltage. It adopts DC instantaneous excite way.
