YCQ9Ms series dual power automatic transfer switch is suitable for power supply

system with AC 50/60Hz, rated working voltage AC400V, rated working current 800A

and below.

It is possible to select and switch between two power sources according to

requirements, ensuring uninterrupted operation of key power sources. When one

power supply has overvoltage, undervoltage or phase loss, it will automatically

switch to another power supply or start the generator.
