Intelligent dual power automatic switching system for AC 50 / 60Hz, rated working voltage 400V, rated current up to 630A dual power supply system, to achieve the common power supply (N) with automatic standby power switch (R) between the (also can be used to manually switch).

LMQ3-W1 intelligent automatic shift switch intelligent dual power automatic switching system for AC 50/60Hz, rated working voltage 400V, rated current 63 ~ 630A dual power system, switch between common power (N) and automatic standby power (R)(can also be used for manual switching) . It is composed of integrated controller and intelligent device. The main body is composed of two groups of circuit breakers installed in the switch cabinet to realize two groups of input terminals and one single-chip dual-power conversion switch for output.

The intelligent device is composed of special forward and backward motors, circuit breakers and operating mechanism. The system has the function of electromechanical double interlock protection, which provides a safe and reliable guarantee for power supply.
