What is the essential difference between the common UPS power supply and eps in real life?
UPS is the abbreviation of Uninterruptible Power Supply, which is what we often say that UPS does not interrupt the power supply. There are two main types of UPS power supplies that are rarely seen in the market: on-line and off-line. EPS Emergency Power Supply System is the abbreviation of Emergency Power Supply. It is an important part of modern building safety guarantee facilities. The general situation is to operate firefighting or to consume power used in anxious situations. Below is the difference between UPS power supply manufacturers to see the two.
1. The development of EPS in the country originated from sudden obstacles in the power grid. In order to ensure the need for power protection and fire protection linkage, it can immediately provide escape lighting and fire rescue. To protect the lives or body of users from damage, its product skills are required to be monitored by the Ministry of Public Security's fire protection certification, and handed over to the site for fire control inspection. UPS is used to protect user equipment or transactions from economic damage, and its product technology requires certification by the Ministry of Information Industry. The two practical safety models obviously have nothing in common and therefore have different values.
Two. Both EPS and UPS can supply two-way output power supply. UPS power supply is to protect the high-quality power supply and adopts inverter priority; while EPS is to protect energy saving, it is adopted Mains power has priority.
3. Because UPS is used online, it is better to call the police immediately when obstacles emerge, and there is mains power as backup protection. The user can immediately grasp the obstacles and eliminate the obstacles. The incident caused even greater damage. EPS is an off-line application, which is about power supply protection at the end. Therefore, its stability arrangement requires higher requirements. If it can not be briefly understood as a backup UPS, the vitality of EPS will be cancelled. If the EPS fails to provide emergency power supply through the battery when the mains power is in trouble, the EPS will be empty, and the results will be unimaginable.
Four, UPS power supply is like estimating machine and collection equipment, the nature of the load (output power factor) is not much different, so the national standard determines the UPS output power because 0.8. The EPS power supply is for power protection and fire safety. The nature of the load is inductive, capacitive, and rectifier nonlinear loads, and its output power factor cannot be set to 0.8 (the EPS national standard will determine its value) And some loads are only added to work after the mains power is cut off, so EPS can supply a lot of impulse current, EPS needs to have better output characteristics, stronger anti-overload ability. Therefore, the technical arrangement and target deployment of each component of EPS and UPS are different.
