2. Performance Benefits of JATSG ATS Changeover Switch

1) Electirc grade: PC grade
2) Usage category: AC33IB
3) Warranty period:18 months
4) Simple form and small size: mechatronics and integration design
5) Safety and Isolation: two power sources independently connect, break, and extinguish arc in isolating and closed space
6) Stronger instant compact resistance capacity: contacts were designed with suction
7) Zero arc: the independent arc-extinguish channels have been set with multiple metal gratings to cut and cool arcs 
8) Three work modes: automatic input and automatic recover (R type); automatic input without automatic recover (S type); mutual stand-by (I type)
9) High capacity in power loading, connecting and switching, and reliable performance in anti-interference, multi-control and noise-free


3. Application of JATSG ATS Changeover Switch

1) monitors power circuit, can automatically switch into the spare power supply when normal power fails.

2) widely used in distribution system with power consumption under AC 380V, 50Hz and rated current 400A.

3) is used for occasional connection, breaking and circuit isolation.

4) typical applications:

4. Functions with 4 controllers: 1) A controller: from utility power to utility power; 2) B controller: compared to A controller, added function of relay time adjustable when transfers, and settings of automatic transfering without recovering and mutual stand-by; 3) C controller: from utility power to generator; 4) D controller: from utility power to utility power, or utility power to generator
