The difference between EPS emergency power supply and UPS

Hello, to put it simply, ** UPS is no switching time, EPS is similar to backup UPS, usually the inverter does not work, the power off inverter only works, and the switching has a time of 20ms. You can refer to the comparison between UPS uninterruptible power supply and EPS emergency power supply system.

1. The definition of essence is different

UPS power supply: UPS uninterruptible power supply is a kind of constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as the main component. Its main function is to reliably and uninterruptedly supply power to computer network systems or other power electronic equipment through UPS systems.

So that the entire network data will not be lost due to power failure accidents.

EPS emergency power supply: EPS is an emergency power supply device that allows short-term power interruption, mainly for emergency lighting, fire fighting facilities and particularly important loads in urban high-rise buildings, especially in solving the problem of lighting electricity or only one mains power supply and lack of a second power supply. Power is supplied to the load only in an emergency situation.

2. Different applications:

In China, EPS emergency power supply is mainly used for electrical equipment in the fire protection industry, emphasizing the function of continuous power supply. Used for fire protection loads: fire alarm systems, fire elevators, fire pumps, smoke prevention fans, emergency lighting, fire shutters, special obstruction lights, etc.

UPS power supply is generally widely used in banking systems, ** systems, telecommunication systems, chemical systems, power systems, airports, hospitals, railways, industrial control centers and electronic computing centers. Its loads, such as computer equipment, communication equipment, fire-fighting equipment, medical instruments, etc., require high power supply quality, emphasizing the requirements of inverter switching time, output voltage, frequency stability, and purity of output waveform.

What is the difference between UPS power supply and EPS power supply? The old electrician tells you one by one, practical electrician technology!

UPS (Uninterruptible Power System), an uninterruptible power supply system that shuts down to battery power, completely uninterrupted, or converted in 10 microseconds. Let the appliance continue to be used without restarting.

EPS is a DC-to-AC inverter. EPS (Emergency Power System) is a marketing term proposed by Chinese manufacturers around 1998. It is mainly for power and lighting power, when the power is off, the generator is not started, but the direct AC inverter is used to supply power from the battery.

There are no strict conversion time requirements, and even some manual switching.

EPS emergency power supply is mainly used for emergency lighting and fire fighting.

EPS is not as efficient as UPS and is used in non-major equipment and environments.

UPS power supply is aimed at precision equipment, such as computer room servers, medical operating rooms.

What is the difference between UPS power supply and EPS power supply? The old electrician tells you one by one, practical electrician technology!

UPS power supply is uninterruptible power supply, responsive and highly reliable.

EPS power supply is mainly emergency lighting, and most of them are customized according to customer requirements.
