The current computer room, system integration, and integrated cabinets are ubiquitous. The existence of rack UPS power supplies has solved many problems. It has provided great help to many computer rooms, data centers, workshops, and units. Existence is inevitable. Rack-mounted UPS rack-type design, the appearance design adopts the most widely used 19-inch standard rack-type chassis, the appearance is simple, and the installation is convenient.
Rack UPS is aimed at China ’s power grid environment and network monitoring, network systems, medical systems, and other power supply reliability requirements. It overcomes the increasingly severe problem of the power grid environment caused by the centralized power supply of medium and large computer network systems. The third-generation power-frequency pure online intelligent UPS developed by technology is an important power supply guarantee device for enterprises.
Rack UPS power supplies are widely used in communication, electric power, public security, fire protection, radio and television, finance, military, Internet and other industries. The matched and integrated equipment includes: communication base stations, integrated power distribution cabinets, data centers, and modular integrated products.

The UPS Lithium-ion Battery System Supplier introduces the rack UPS in detail.
Rack UPS power system consists of five parts: mains, bypass, battery and other power input circuits, AC / DC converter rectifier (REC), DC / AC converter inverter (INV), inverter and Bypass output switching circuit and energy storage battery.
UPS Lithium-ion Battery System
Normally, the mains power is converted to direct current to charge the battery by a rectifier, and at the same time, the inverter outputs high-quality AC purified power for important loads, so that it is not affected by the mains voltage, frequency and harmonics. When the mains power fails for some reason, the system automatically switches to the battery pack, the battery discharges, and the inverter supplies power to the important load.
The rack UPS power supply rectifies the mains AC power when the machine is working and stores it in its own power supply. Once the power supply is stopped, it can provide power and use electrical equipment to maintain a working time. The holding time may be 10 Minutes, half an hour, etc. The delay time is generally determined by the capacity of the battery.
When the utility power is supplied, it is the role of the voltage regulator and filter to eliminate or weaken the interference of the utility power and ensure the normal operation of the equipment; when the utility power is interrupted, it can provide the The DC power is converted into perfect AC power for the load. Among them, the mains power supply to the battery power is usually switched in 0 hours. This allows the load equipment to keep running without feeling any changes, which truly guarantees uninterrupted operation of the equipment.
The above is the information about the rack UPS introduced by the ESS All-In-One supplier. Hope to help everyone.
