What is the difference between portable UPS power supply and emergency power supply in terms of output power supply

The object of power supply of portable UPS is computer and network equipment. There is little difference in load properties, so the national standard stipulates that the UPS output power factor is 0.8. In order to ensure uninterrupted output power supply and high quality power supply, online portable UPS is preferred to inverter.

The emergency power supply is mainly used as the emergency guarantee of the power supply, and the load nature is both inductive, capacitive and rectifier loads. Some loads are put into operation after the mains power is cut off. Therefore, EPS is required to provide a large impact current. Generally, it is required that EPS can still operate normally for more than 10 minutes under 120% rated load. Therefore, EPS needs to have good output dynamic characteristics and strong anti overload capacity. In order to ensure emergency use of EPS power supply, the municipal power supply is preferred.
