Difference between UPS and EPS power supply(section two)

Second, the classification and principle of EPS
Working principle of EPS similar backup UPS power supply type, generally by the charger, inverter, battery, automatic switching device, control system, is characterized by simple structure, no noise, long service life.  Emergency power supply for homes, applicable to the inductive, capacitive and comprehensive load.
The classification of the EPS
According to the load types can be divided into: 1) 2) emergency lighting and emergency lighting type hybrid 3) dynamic power
Third, the difference between UPS and EPS
1) according to the output difference between UPS and EPS
China ups power supply object basically is the computer and network equipment, the nature of the load is low, the current regulation of UPS output power factor of 0.8.EPS is mainly used for power supply and emergency safeguard, usually for inductive or capacitive load properties. Some power load is required before put into use, all the impact of the EPS must be able to provide a large current, usually require under 120% load can continue to supply more than 10 minutes.UPS for the unit with the KVA rated capacity, rated capacity of EPS in KW.
2) the function of UPS and EPS difference
EPS and UPS has the utility bypass and inverter circuit, but EPS only has the function of continuous power supply, the inverter switch time requirement is not high, at present most of the EPS has monomer battery detection.EPS inverter output after a mains failure, improve the utilization of computer.
The UPS uninterruptible power supply generally emphasize its three functions: the mains frequency stabilization and voltage stability; High power equipment to switch time requirement; Purify the mains.Daily double conversion circuit of the rectifier and inverter power supply, power utilization rate is not high. But not just when the power inverter power supply, UPS can also appear in mains voltage deviation, such as surge abnormal situations to provide stable power output, what is this EPS does not have.
3) UPS and EPS in the scope of application of different
EPS is mainly used for fire protection class load and some to switch time requirement is not high, but requires constant power supply equipment.
UPS is mainly used for computer, digital information system for power supply quality requirements such as high load. For more information, please visit www.rendapower.com.
