The difference between the concentrated EPS emergency grid tie power inverter and fire emergency lighting

Now high-rise buildings, shopping malls, casinos, etc must be fire emergency lighting, that in the light of the fire emergency lighting or emergency lighting EPS fire power inverter , let us together to compare.

Fire emergency lighting is to point to to guarantee in the event of a fire accident, in the absence of external power inverter, can ensure that the lighting, help light-emitting personnel escape to a kind of power inverter appliances. 

It usually use an external power inverter, when the power switch to using a state. 

At present lies in high-rise buildings, shopping malls, entertainment venues such as personnel intensive place of widely used.

EPS is also called the EPS power converter , EPS emergency power converter, fire emergency power converter, the full name of EmergencyPowerSupply (emergency power converter), is the important for electric power security and fire safety in buildings and adopt a kind of emergency power converter. 

It is mainly composed of input and output unit, a charging module, battery, inverter, monitor, output switching device and other parts.

Widely used in building lighting, road lighting, electric power, industrial and mining enterprises, fire elevator (fire pump) and other fire fighting equipment.

1, emergency lighting power switch time after 2 seconds, there will be a failure, EPS emergency grid tie power inverter and switch time can be up to 0.18 milliseconds, won't appear off electricity situation.

Number 2, fire emergency lighting lamps and lanterns and a lot of, don't have the function of the centralized management, is not convenient to manage, only know whether the lamps and lanterns light the lamps and lanterns is normal, and EPS centralized intelligent management, remote monitoring grid tie power inverter, to monitor the quality of battery internal resistance and so on can, achieve preventable and controllable, low fault rate and easy management.

3, emergency lighting lamps and lanterns or move only commonly, small capacity, generally for 4 ah battery led lamps and lanterns, general life is 1 year, maintenance cost is high.

EPS fire emergency power battery life of general design for 5 to 8 years, host life of 25 years, maintenance costs low.

4, the types of emergency lighting lamps and lanterns of strict requirements, EPS grid tie power inverter of lamps and lanterns is not required.

And EPS grid tie power inverter for fire fighting pumps, etc. In addition to the emergency lighting fire load.

Of course is the advantage of EPS grid tie power inverter emergency lighting lamps and lanterns is incomparable, but in the early period of the EPS power supply input is relatively high.
