Summarize
Talented EPS ,whose the main aim is to solve primary load power supply equipment
such as emergency lighting, accident lighting and fire facilities etc,supply emergency power supply system with independent circuit and accord with fire codes. The system can provide emergency power supply in emergency situations to solve the problem of lighting power, only one way city power and lack of second power supply, or replace the generator sets as second power, or be used in the occasion where it needs the third power.
The emergency power supply system of our company contains four series of products, namely:
(1)L series: From 1 KW to 100 KW, mainly provide centralized power supply for emergency lighting places;
(2)S series: From 2.2 KW to 500 KW, the series are used in all kinds of single-phase, three-phase and hybrid electric equipment,such as emergency power supply of elevators, fan, water pump, lighting ,air conditioning, etc;
(3)M series: From 2.2 KW to 500 KW, the series,as emergency power supply, are specially designed for electric motor load for the fire protection facilities who have only one way power supply or the motor in primary load;
The power supply is specially designed for the fire fighting equipment and a load of electrical equipment.The principle is shown in the figure below. When the AC power grid is normal, the power of important load is supplied by the power grid through the change-over equipment. When the power grid is failed, the power supply will be switched immediately to the inverter by change-over equipment. When the power grid is recovery , the emergency power supply will be supplied by the power grid.
Features
Mature SPWM and IGBT inverter technolog and high reliability
Set inverter, charger and controller in one
The main power state and emergency automatic switching, there is a fire linkage interface, to ensure normal power supply.
It has the function of battery automatic inspection, can display the battery state and realize fault protection of the single battery.
Alarm when Sound and light are fault ,and can indicate the type of failure.Perfect protection: protect the over discharged battery , the output in short circuit, the battery in short circuit and charger in short circuit and so on.The main cabinet and battery cabinet are separately design for the transport and installation and flexibly expanding the battery.
The main inverter adopt modular design, can be fully repaired and operated in front, suitable for all kinds of complex environment.
Optional battery can be realized automatic float management, temperature compensation,to protect effectively the battery and save the operation and maintenance of cost .
Optional 140-280V grace input, suitable for the use of large areas of voltage fluctuations.
Optional function record of the historical event.
Optional remote monitoring function.

Advantage of EPS
EPS compares with the traditional in emergency mode:
A.Two power supply modes:the mode of the traditional emergency adopts two independent power supply when the power grid supplies the power. If the main power supply fault, power is supplied by the standby power lines.Although this way is simple and reliable, the electricity line is complex. When there is a large area blackout accident, two power supply are likely to have a power failure accident.
B.Adopt back-up diesel generator power supply mode: the mode for emergency power supply has low cost, but starting of diesel engine needs tens of seconds intervals. Even diesel engine has autostart function, still need person to maintenance and recondition. Meanwhile, it will release a large of harmful gas and noise when generator is working .So it is not suitable to install in buildings, such as office space.
C. UPS power supply modes: make sure the load “without risk at all". But UPS are expensive, especially the online UPS. The conversion efficiency of this equipment is low. If it works in long-term continuous condition , it will lead to waste of energy. In fact, UPS is widely used in the information load.So it is a waste of using UPS in emergency lighting occasions.
D. Decentralized emergency lighting modes: this way is the most widely used in the fire safety currently, but only limited to emergency lighting.With popularization of intelligent building and perfect fire safety facilities, it is not only used to the lighting power supply ,but also to power supply for water supply, ventilation, monitoring and other emergency equipment. At this time, the emergency lighting has become powerless.
Our product adopts centralized emergency power supply, which overcomes the shortcomings of the above ,and has the advantages of high performance price ratio, easy installation, high efficiency and so on.
