1.Product Name: Emergency Lighting Centralized Power Supply.
2.Executive standard: GB17945-2010
3.Key components: transformers, inverters.
4.Product features:
When the city voltage is normal, the alternating current directly supplies power to the load through the mutual projection device of the emergency lighting centralized power supply, and the internal charger charges the battery pack at the same time. When the mains power is out or the mains voltage is lower than 15% or higher than 10% of the rated voltage, it will immediately switch to the inverter output power supply, and the battery pack will output alternating current through the inverter to continue to provide power to the load.
5.Place of use:
It is mainly used in airports, rail transit, tunnels, passenger transport hubs, hospitals, schools, gymnasiums, exhibition halls, star-rated hotels, high-end commercial buildings and other places.
6.Certification mode: type test + initial factory inspection + post-certification supervision (compulsory certification).
7.Principles of unit division:
1) The main circuit layout is different, and it cannot be used as a unit;
2) The main technical indicators of transformers and inverters are different (except for different power parameters) and cannot be used as a certification unit;
3) The battery charge and discharge control circuit layout is different, and it cannot be used as a certification unit.
8.Inspection cycle: 90 days for type test, 60 days for typing test, 40 days for supervision and inspection.
9.Number of inspection samples: 2 types test, 1 type test, 1 supervision and inspection.
ps.The fire emergency lighting and evacuation indication system works with the use of fire alarm controllers to help people in the building choose the best escape route in real time and guide the safe escape direction in critical moments.
