we can use portable soalr power generator charge for EPS emergency power supply is based on fire-fighting facilities, emergency lighting, emergency lighting and other equipment needs a load power supply and the composition of the power supply. emergency power supply is based on fire-fighting facilities, emergency lighting, emergency lighting and other equipment needs a load power supply and the composition of the power supply. Products from each switch device, automatic battery chargers, inverters and batteries and other components. Inverter does not work in the AC mains is normal, after each vote an important device to load. When the AC power grid after each switch device will immediately switching to the inverter power supply. When the grid voltage is restored, each switch device will be switching to AC grid.
Emergency power during a power outage can be on different occasions for a variety of electrical equipment power supply. It is suitable for a wide range, strong load adaptability, easy installation, high efficiency. Centralized power supply emergency power to overcome the many shortcomings of the other power supply. Reduce unnecessary energy waste. Emergency accident, lighting and other electrical properties, it is associated with a lower conversion efficiency and long-term continuous operation of the UPS uninterruptible power supply, compared with higher cost performance.
UPS emergency power supply (also called DC emergency power supply) is an emergency power supply device for today's power to protect important buildings and fire safety and the use of; widely used in construction field of electrical power and the emergency special occasions, the principle is: AC when normal power grid, the AC power grid after each vote an important device to power the load when the AC power grid, each switch device will immediately switching to the emergency power supply DC power supply, when the grid voltage is restored, the emergency power supply will be restored to the power grid for use lifepo4 batteries like lifepo4 battery for storage power, avoid personal injury and property damage when a disaster occurs.
First, by the fire emergency lighting, fire work light switch system composed of, for fire fighting and rescue personnel provided, usually set in such an important place for power distribution room, fire pump, fire control center, communications center its emergency work time should not be less than 90min, and to meet the normal work of illumination requirements.
Second, the fire emergency evacuation lighting composed, fire evacuation function of the system, when the evacuation order, and provide the necessary illumination settings, usually set to public walkways, vertical stairwell, their emergency response time is not less than 90min illumination of not less than 0.5Lx.
Third, the low fire emergency evacuation lighting and emergency evacuation, and emergency evacuation identification system functions other signs in the form of the composition by solar powered portable generator, in case of emergency for the evacuees, provide clear guidance direction and way, usually installed in shopping malls, cinemas and other personnel intensive public walkway large public places, as well as vertical staircase, usually located on the ground or from the ground 1m or less, that its emergency lighting emergency work time not less than 90min, lights the main standard interface surface brightness can not be less than 15cd / m2 .
