Application of data center and UPS
Data Center Overview:
Data? centers? are? globally? collaborative? specific? networks? of devices used in IntraTransfer, accelerate, display, calculate, and store? data? and? information? on? the? network? infrastructure.? Most electronics in the data center are driven by low-DC power supplies.
The emergence of data centers has led peoples understanding from the? quantitative? and? structured? world? to? the? uncertain? and unstructured? world.? It? will? gradually? become? a? part? of? the infrastructure of modern society, just like transportation and network communication, and then have a positive impact on many industries. However, the development of data centers should not only rely on experience, but also really combine with practice to promote the data centers to play a real value role and promote the rapid social change.
A Schematic diagram of the UPS system
-
uninterruptible power supplyUPS is an uninterruptible power supply, which is an?uninterruptible power supply containing energy storage devices. It is mainly used to provide uninterrupted power supply for someequipment with high requirements on power supply stability requirements.
-
working principleWhen the mains power input is normal, the UPS supplies the mains power after voltage stabilizationLoad use, the UPS at this time is an AC currentThe regulator also charges the battery; when the mains power is interrupted? (accident outage), the UPS immediately passes the direct current of the batteryThe method of inverter switching and conversion continues to supply 220V or 380V to the loadAC to keep the load working and keep the load softThe hardware is not damaged.UPSEquipment usually provides protection for either too high or too low voltage.
-
UseIn the data center, the parallel redundant UPS system composed of dual transform UPS single unit is generally used. When the datacenter load is for dual power supply, the parallel redundant UPS is used to form the dual bus UPS power supply system.
Features of lithium battery UPS
The lithium battery UPS system, combined with the characteristics of high energy density, small footprint, long service life, high safety performance, convenient operation and maintenance mode, can provide high quality power guarantee for the data center, IT room and major key loads in the fields of communication, IT and industrial fields.
-
protection functionsThe charge and discharge cycle times can reach 5000 times, and the service life can reach 10 years. The BMS battery management system has perfect protection functions (short circuit, overcurrent, overcharge, overdischarge, overtemperature, etc.)
-
protection controlLithium UPS system has three-level protection control, UPS and BMS realize the whole monitoring of dual lithium battery backup?system
-
standardized designPACK module standardized design can be freely combined, and the volume and weight are 1 / 3 of lead-acid battery, which is more suitable for spatially limited application scenarios

Features of lithium battery UPS
In addition to data center lithium UPS, there are more commonly?used backup, online UPS, mainly used in government, education, finance, communication, insurance, transportation, tax, securities, and other
fields.
Lead-acid batteries in energy storage applications are still mainly used in these areas
