Dual power automatic switchover cabinet

Dual power supply automatic switching device, suitable for switching between two power supply (common power supply and standby power supply) whose rated voltage AC does not exceed 1000V and DC does not exceed 1500V or below due to the abnormality of one power supply, ensure the safety and reliability of power supply in time. Product Feature 1: two electric operated circuit breakers with electrical interlock and mechanical interlock devices work accurately and reliably in the use of a circuit breaker. 2: the device uses high-breaking capacity circuit breaker, and has overload, short-circuit protection. 3: the device can be provided with two forms of manual switching and automatic switching. The automatic switching switch has two forms: self-turning self-turning and self-turning non-self-turning. To test the three-phase voltage of two power supply (common power supply and standby power supply) at the same time, any phase over-pressure, under-voltage (including lack of phase) , power failure and other faults can delay from the conduction constant power supply side to normal power supply to ensure that the power supply fault-free output.
