UPS power supply: UPS uninterruptible power supply, is a kind of containing energy storage device, inverter as the main component of the constant voltage, constant frequency uninterruptible power supply. Its main role is through the UPS system, the computer network system or other power electronic equipment reliable and uninterrupted power supply. So that the entire network data will not cause data loss due to power failure accidents.
EPS emergency power supply: EPS is an emergency power supply device that allows short-term power interruptions, mainly for the city's high-rise buildings in the emergency lighting, firefighting facilities, and especially important loads, especially in the solution of the lighting power or only one way of the utility lack of a second power supply. Only in the emergency state for the load power supply.
2, the application of different:
In the domestic, EPS emergency power supply is mainly used in the fire industry power equipment, emphasizing the ability to continue to power this function. Used for fire loads: fire alarm systems, fire elevators, fire pumps, smoke exhaust fans, emergency lighting, fire shutters, special obstacle lights and so on.
UPS power supply is generally widely used in banking systems, securities systems, telecommunications systems, chemical systems, power systems, airports, hospitals, railroads, industrial control centers and electronic computing centers. Its load, such as computer equipment, communications equipment, fire equipment, medical equipment, etc., requires a high quality of power supply, emphasizing the inverter switching time, output voltage, frequency stability, and the purity of the output waveform and other requirements.
