Many people think that there is no difference between UPS power supply and EPS power supply, and they can also achieve interoperability in terms of usage. However, in reality, there are certain differences between these two types of power supply. Below, the editor will elaborate on the following aspects for everyone.UPS, also known as Uninterruptible Power Supply, is an uninterruptible power supply that contains energy storage devices. Mainly used to provide uninterrupted power supply for some devices that require high power stability.EPS emergency power supply is commonly used for firefighting equipment, emergency and accident lighting, etc.[Click on the image to view more products from Haibo Electric]

Work process:When the mains power is normal, UPS is rectified by the mains power, providing DC voltage to the inverter for operation, and the inverter provides AC power to the load. At this time, UPS is an AC mains voltage stabilizer, and DC power is also charged to the internal battery. In case of abnormal power supply, the inverter is powered by the battery to continue supplying AC power to the load, maintaining normal operation of the load and protecting the load's software and hardware from damage.. Since the inverter is always in operation, the output will not be interrupted.EPS is when the mains power is normal, and the mains power supplies power to the load through the mutual switching device, while conducting mains power detection and battery charging management.
When the mains power supply is interrupted or the voltage exceeds the limit, the mutual switching device will immediately switch to the inverter for power supply, converting the DC energy stored in the battery pack into AC power output, and supplying stable and continuous power to the load equipment. When the mains power returns to normal, the EPS inverter shuts down and performs a switching operation from the inverter to the AC mains power supply.Yantai Haibo Electrical Equipment Co., Ltd. focuses on the research and development and technical promotion of battery management systems (BMS), industrial lithium iron phosphate battery packs, and intelligent AC/DC power supply sets, committed to providing overall technical and product solutions for new energy applications, energy conservation and emission reduction.

Application field:
Functional features:
UPS: Stable voltage and frequency, high output accuracy; Fast conversion time, 0-10ms; Usually, dual conversion circuits supply power, and only switch to bypass power when the inverter malfunctions or is overloaded, resulting in low energy utilization.EPS: It is similar to a backup UPS, where the inverter does not work normally and the battery is only put into operation when the mains power is cut off. Generally, the power supply is not subjected to constant current or constant voltage treatment. Usually, contactor conversion is used, and the switching time is between 0.1 and 0.25 seconds. Its advantages are simple structure, low cost, low energy consumption and no noise in daily life. It can adapt to inductive, capacitive, and comprehensive loads, and can achieve variable frequency soft start when needed.Yantai Haibo Electrical Equipment Co., Ltd. focuses on the research and development and technical promotion of battery management systems (BMS), industrial lithium iron phosphate battery packs, and intelligent AC/DC power supply sets, committed to providing overall technical and product solutions for new energy applications, energy conservation and emission reduction.
