With the continuous progress of technology, circuit structure update and improvement, UPS power supply circuit structure of a variety of forms, various forms of UPS uninterruptible power supply has emerged. The following ups power supply technical overview describes the main ways to place the UPS uninterruptible power supply.
How many ways can the UPS uninterruptible power supply be placed in space?
The UPS power supply contains a battery pack that "starts" when the device detects a power failure from the main power supply. The battery pack provides uninterrupted power to some devices that require high power stability. The UPS uninterruptible power supply can be divided into three forms in terms of space occupation, namely tower type, rack type and module type.
① Tower type
Tower UPS is like an ordinary computer, is standing, the height is generally 10U(U is the height unit of the server, about equal to 4.5cm), the UPS power occupies a small space, can be placed freely, without the need for a special cabinet, almost all household UPS uninterrupted power is tower.
The characteristics of the tower UPS are that it can realize online double conversion, separate placement and landing installation, which is also required for space. In most cases, a rack UPS can also be mounted in a tower, but a tower UPS may not be able to be mounted in a rack, because a tower UPS may not be able to mount a rail.
② rack type
Rack UPS uninterruptible power supply is basically the opposite of the tower, is horizontal, the size will be wider, generally are directly placed in the corresponding cabinet. This cabinet, which usually contains servers and so on, plus a UPS battery pack, is a large functioning cabinet.
The rack can be installed in a 19-inch standard server cabinet (the size can be customized as required) and secured in a standard network cabinet through guide rails. The height of the lithium-ion battery UPS is 1U or 2U (about 9CM). The UPS must be placed in the server cabinet. Rack-mounted UPS uninterruptible power supply, almost are used in the enterprise environment, modern machine rooms are basically rack-mounted servers.
The UPS power supply is characterized by small size, large capacity, high efficiency, and small space occupation. Rack UPS are widely used in communication, electric power, public security, fire protection, radio and television, finance, military, Internet and other industries.
③ Modular
As for the modular, it can be understood that the rack-type UPS power supply, like building blocks, collects points into planes, splices them together, and then installs them in the corresponding position. Modular UPS uses a modular structure to facilitate installation and expansion. You only need to add modules. The advantages of the modular UPS power supply are as follows:
Investment effectiveness: Capacity expansion on demand, saving initial investment;
Easy maintenance: online hot swap, simple and fast maintenance, no bypass;
Energy saving and environmental protection: low pollution to the power grid, high efficiency and module dormancy technology to reduce energy waste.
Energy saving and consumption reduction: Today, the national advocate of environmental protection and energy saving, green energy saving lithium modular UPS attention, input power factor up to 0.999 or more.
