The difference between the UPS power supply and the EPS power supply is mainly reflected in the working mode, application, component construction, load type, selection configuration, component selection requirements, fire characteristics, safety performance, and fire acceptance, etc., the following is made Specific analysis, let everyone know.
The rated capacity of the UPS power supply is in KVA, the rated capacity of the EPS power supply is in KW. The power supply object of the UPS is mainly computer and network equipment, the load is low, and the power factor of the UPS output is currently 0.8. EPS is mainly used for power emergency protection, usually the load properties are inductive or capacitive. Some loads are required to be put into use after power-on, and all EPSs must provide a large impact current, usually requiring to supply more than 10 minutes by 120% of the load.
It can be seen that the UPS power supply has a significant difference from the EPS power supply. Plus the EPS emergency power supply will have a few seconds of switching, and the UPS uninterruptible power supply is zero switching, so a more strict device using the site must use the UPS power supply Instead of EPS power, such as hospital ICU intensive care room equipment, computer room servers, computers, etc., or other sites that need to use UPS uninterrupted power supply. So everyone gives a reasonable configuration for the requirements of the desired environment in selecting the emergency power supply, making the device play a more effectiveness.
UPS is an online application, an abnormality can be an immediate alarm, and there is a voltage reserve to ensure that the user can pay close attention to frequent failures and failure detection, which is not easy to cause greater damage to the safety accident. EPS is to ensure energy saving, which is to choose the mains. The EPS power supply is offline, and it is the latter power supply. If EPS is in a market failure, the EPS will not be powered by the battery, and the EPS is like dummy, the consequences will be unimedious.
The UPS power supply requires high supply quality, emphasizes inverter switching time, output voltage, frequency stability, output wave type, positive, regulator tube, filtration, and other requirements, to protect user equipment or business from economic losses, commonly used In strong and weak motor rooms, computers, precision instruments, etc.
