Emergency Lighting Power Supplies Are Stand-alone Power Sources Taken From The Grid

When the emergency lighting power supply is an independent power supply taken from the power grid, it is required to attract two independent power supplies from the outside to ensure that when one fails, the other continues to work. The emergency lighting distribution system should be self-contained to ensure that in the event of a fire, the system can still supply power unless the fire load is carried out. In this way, the power supply capacity and power supply time are not limited, and the conversion time is easy to meet the requirements. However, in the event of a major disaster, its power supply reliability may be compromised. Therefore, for large-scale high-rise buildings and some particularly important buildings, it is not enough to use this way as emergency lighting power supply, and it is necessary to use generator sets or batteries as necessary supplements and reinforcements for emergency lighting power supply.
