Description：The series intelligent double-power automatic transfer switch (hereinafter referred to as switch) is used as a molded case circuit breakers or switch actuators, together with the microcontroller as the core electrical and mechanical interlocking with automatic controller and the control of institutions, is a performance improved, safe, reliable, high degree of automation, the use of a wide range of dual-power automatic transfer switch. Suitable for AC 50/60Hz, 690V and below, rated current from 6A to 1250A and below the two power supply (commonly used power N and the standby power or generator power R) power supply system, due to the way a power failure (power outage, undervoltage, overvoltage, phase, frequency offset) and to automatically switch between the power supply to ensure power supply reliability and security.

 

Applications：High-rise buildings, residential, hospitals, airports, docks, fire, metallurgy, chemicals, textiles and other important places do not allow power to achieve continuous power supply unattended
