Dual power control box ATS
1. Scope of use
It is applicable to the switching between two power supplies (common power supply and standby power supply) with rated working voltage of 690V AC and frequency of 50 Hz. It has the functions of automatic switching of overvoltage, undervoltage, phase loss and intelligent alarm. When the common power supply fails, it can automatically complete the switching from the common power supply to the standby power supply (there is mechanical interlock and electrical interlock between the two circuit breakers) to ensure the reliability, safety and continuity of the power supply for the load.
This device is applicable to hospitals, shopping malls, banks, hotels, high-rise buildings, facilities and fire control and other important places where power failure is not allowed. The product meets the requirements of various specifications such as Code for Fire Protection of High-rise Civil Buildings and Code for Fire Protection Design of Buildings.
