The difference between UPS power supply and EPS power supply

EPS is the fire emergency power supply, and UPS is the uninterruptible power supply. From a textual point of view, the two are different. What’s the difference? Sungzu Xiaobian tells you about the similarities and differences between EPS and UPS.

1. Different power supply methods

EPS uses offline power, which is the final power guarantee. When the utility power fails, if the EPS cannot be powered by a battery emergency, it is like a dummy, and the consequences will be unimaginable.

The UPS uses the online power supply. Even if there is a fault, it can alarm in time and use the public power supply as backup protection. The user can grasp the fault and eliminate the fault in time, and will not cause more damage to the accident.

2. Power selection is different

EPS is the city’s power priority to ensure energy savings.

The UPS is the inverter priority to ensure power supply.

3. The technical design indicators of the components are allocated differently.

EPS primarily provides power for power protection and fire safety. Load characteristics include inductors, capacitors, and rectified non-linear loads, some of which are put into operation after a power outage. Therefore, EPS needs to provide a large surge current, and the output dynamics are stronger and more resistant to overload.

UPS mainly supplies power to computers and network equipment, and the load characteristics (input power factor) are not much different.

4. Different objects

EPS mainly responds to sudden power grid failures, provides emergency lighting and fire emergency, ensures power safety and fire protection, and protects users’ lives. Products need to pass the fire protection certification of the Ministry of Public Security and accept fire inspection at the installation site.

UPS is used to protect user equipment or businesses from economic losses, and products need to be certified by the Ministry of Information Industry.
