UPS host is installed on the wall, its battery cabinet is installed below the UPS host.

Protection of computers storing important information
Due to instability of the power source and voltage or other reasons, the computer might suffer sudden power failure. To a general computer, the sudden power failure is very common to see. However, if a computer is stored with important information, it might cause immeasurable losses to the user.

The UPS work modes can be divided into the on-line and off-line. The off-line UPS is also known as the reserve UPS, which can be further divided into the UPS with the sine wave output, square wave output, voltage stabilization or no voltage stabilization.

Trace points
The multi-core soft wire is the best choice for all input and output copper cores for the convenience of the user’s cabling and the machine’s wiring. The ground wiring for the machine input and output should adopt the metal protection cover (particularly the wiring under the anti-electrostatic floor of the machine room) to prevent the mouse’s biting, accidental consumption, and burning-caused fracture. The metal protection cover can shield the electromagnetic interference, which is convenient for underground wiring of communicational devices’ signal wires.

Below are major components and functions of the UPS:
Generally, the UPS is made up of the charger, inverter, static transfer switch, and accumulator.
Below is a brief introduction of different parts of the UPS:
1. Role of the charger
Absorb energy from the main power supply. Generate the DC via the bridge SCR current and resistance filtering current. Directly provide the DC for the accumulator and the inverter.

The digital center copes with important information, and this information is of vital importance to operation of the institution. Therefore, the power supply of the data center can meet need around the clock all day long. However, this cannot yet ensure full satisfaction of all needs. Some precautions should be taken, and the whole digital center’s power supply will not have problems under emergency. Therefore, it is necessary to install the UPS to ensure consistency of power supply. Of course, the UPS’s capacity is limited, though it is applicable to the IT infrastructure, including computer systems, servers, routers and so on. However, it cannot be applied to heavy equipment.

Q: What a role does the UPS play?
A: With the development of information and technology, the network has become an indispensable part of people’s life and work. Reliability of power supply of the digital machine room constituting the network has become a linchpin. The UPS emerges to cope with the need of uninterruptible power supply. Voltage stabilization, filtering and no interruption constitute three basic functions of the UPS.

When identifying the UPS power supply, it can be judged from the appearance. Observe whether the appearance is deformed or not, whether there’s a protrusion or leakage, whether the UPS explodes, and whether there’s oxide leakage at the screw joints.

UPS is a constant-voltage and constant-frequency uninterrupted power supply with energy storage device inside and inverter as its main component, it’s mainly used to provide uninterrupted power supply to a single computer, computer network system or other electronic equipment. When the power grid supplies power normally, UPS stabilizes the power supply and then supplies to the load, at this time, UPS is an AC voltage regulator.

In redundant cold standby, the power supply consists of several modules with same function. Under normal conditions, one module supplies power; When it gets faulty, the standby module starts immediately to work. Such a mode would cause a switching time between batteries, thus leaving a voltage gap.

System structure of the modular UPS is quite flexible. The design concept of power module makes the system available to be removed or installed randomly during operation without affecting the system operation and output, thus enabling the investment to expand with the modular UPS and promote users to grow dynamically with business development. It not only meets the demand expansion of later equipment, but also reduces the initial purchase cost. Users would often overestimate or underestimate the UPS capacity, modular UPS solves this problem effectively and helps users build and invest in stage when the future development direction is not clear. When user load needs to be increased, users only need to increase power modules according to the planning stages.

Functions of UPS: When the power grid voltage is normal, the commercial power voltage is supplied to the load after being stabilized by UPS, UPS with a good performance is an excellent AC regulator, it can also improve the quality of power supply. Meanwhile, it also recharges batteries inside the device to storage energy. When the power grid voltage is abnormal, the UPS inverter converts the DC power of battery to the AC power, so as to maintain power supply to load. On-line UPS switches freely between grid power supply and battery power supply, so as to ensure uninterrupted power supply to load.
