What is the device that powers the server called?

UPS is the English abbreviation of uninterruptible power supply, which is an important external device that can provide continuous, stable and uninterruptible power supply**.

In principle, UPS is a kind of power electronic equipment that integrates digital and analog circuits, automatic control inverters and maintenance-free energy storage devices;

Functionally speaking, UPS can effectively purify the mains when there is an abnormality in the mains; It can also provide power to computers and other equipment for a certain period of time when the mains power is suddenly interrupted, so that you can have enough time to deal with it;

In terms of use, with the advent of the information society, UPS is widely used in all aspects from information collection, transmission, processing, storage to application, and its importance is increasing with the increasing importance of information application.

Among them, we most commonly use the backup UPS, such as the four-way HO series and SD series, it has the most basic and important functions of UPS such as automatic voltage stabilization and power-off protection, although there is generally a conversion time of about 10ms, the alternating current of the inverter output is a square wave rather than a sine wave, but because of the simple structure and has the advantages of cheap and high reliability, it is widely used in microcomputers, peripherals, POS machines and other fields;

** UPS structure is more complex, but the performance is perfect, can solve all power problems, such as four-way PS series, its significant feature is that it can continuously output pure sine wave alternating current with zero interruption, and can solve all power supply problems such as spikes, surges, and frequency drifts; Due to the large investment required, it is usually used in power-demanding environments such as critical equipment and network centers;

In addition, Sitong, APC and other manufacturers also provide the best interactive UPS, compared with the backup type, the interactive type has a filtering function, strong anti-mains interference ability, the conversion time is less than 4ms, and the inverter output is an analog sine wave, so it can be equipped with servers, routers and other network equipment, or used in areas with harsh power environments; In particular, the UPS of the four-way MD series, which is far lower than the type, is a better choice that should be strongly recommended to users.

According to IDC statistics, 45% of all computer failures are caused by power supply problems; In China, the average number of power outages in large cities is the next month, in medium-sized cities is two months, and in small cities or villages and towns is four months, and there are at least nine problems in the power grid: power outages, lightning spikes, surges, frequency**, voltage mutations, voltage fluctuations, frequency drift, voltage dips, and pulse interference; Therefore, from the perspective of improving power quality, it is necessary to equip the computer with a UPS.

In addition, sophisticated network equipment and communication equipment are not allowed to have power interruption, the network center with the server as the core should be equipped with UPS is self-evident, even if it is an ordinary computer, the value of software such as data files after three months of use has exceeded the value of hardware, so it is also very necessary to be equipped with UPS to prevent data loss.

You should be talking about UPS (uninterruptible power supply system), which is installed between the power supply and the server, and can automatically switch to the internal battery power supply of UPS in the event of an external power failure without data loss caused by sudden power loss.

What is a server power supply, computer terminology is explained

There are two kinds of server power supplies, one is redundant server power supply and the other is high-power power supply. The redundant server power supply is composed of two PC power supplies, the two power supplies are connected through some special circuits, when a Pi Zheng state power supply is working, the other power supply is in a standby state, when the working power supply suddenly fails, the other backup power supply can take over the fault power supply in a very short time to work, so as to prevent the server from "downtime" phenomenon. Redundant server power supplies are generally used in banks, telecommunications and other non-"down" fuel source doors, and are often not suitable for ordinary consumers.

Server power supply refers to the power supply used on the server, which is a kind of switching power supply like PC (personal computer) power supply. According to the standard, server power supply can be divided into ATX power supply and SSI power supply. The ATX standard is widely used and is mainly used in desktops, workstations, and low-end servers; The SSI standard is produced with the development of server technology and is suitable for various grades of servers.
