Emergency power supply is designed and produced according to the needs of first -level load supply equipment such as fire protection facilities, emergency lighting, and accident lighting. The product consists of a investment device, an automatic charger, a inverter power supply, and a battery pack. When the AC grid is normal, the interoperability device is powered on the important load. When the AC power grid is broken, the mutual investment device will immediately invest into the inverter power supply. When the power grid voltage is restored, the emergency power supply will be recovered to the power grid.  
 
When the emergency power supply is power out, it can supply power on various electric equipment on different occasions. It has a wide range of applications, strong load adaptability, convenient installation, and high efficiency. The use of concentrated power supply can overcome many shortcomings of other power supply methods. Reduce unnecessary power waste. In emergency accidents, lighting and other electric fields, it has a higher performance price ratio compared with the low -conversion efficiency and long -term continuously running UPS uninterrupted power supply.
