What does UPS refer to in a computer

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.

Emergency power supply is called uninterruptible power supply. To prevent data loss and hardware damage caused by the computer power failure after the normal power supply stops, the UPS power supply is not to power the computer, but to give the computer backup power after the normal circuit is powered off, save the data immediately, shut down, or leave a margin time to repair the power failure problem. I don't usually sing at a time, about 30 minutes.

Reply to hl000499, the civilian level will not be long, generally about 5 minutes, very cheap, hundreds to thousands. The industrial industry is relatively long, 15-180 minutes are available, and the military directly uses backup motors. I'm a chemical worker, so I'm familiar with it.

The power industry is called DC screen, and it is a larger thing.

It is called uninterruptible power supply, which is a kind of equipment that provides follow-up time and stable and pure power supply for precision equipment such as computers when there is a sudden power failure or voltage instability.

Uninterruptible power supply, not long and absolutely no 30 minutes.

UPS stands for uninterruptible power supply.

UPS is a kind of uninterruptible power supply with constant voltage and constant frequency containing energy storage device and inverter as the main component. It is mainly used to provide uninterrupted power to a single computer, computer network system or other power electronic equipment**. When the mains input is normal, UPS will stabilize the mains voltage to the load for use, at this time the UPS is an AC mains voltage regulator, and it also charges the battery in the machine; When the power is interrupted, UPS immediately converts the power of the battery in the machine to the load through the method of inverter conversion, so that the load can maintain normal operation and protect the load software and hardware from damage.

UPS devices are often protected against both excessive voltages and excessively low limb voltages.

UPS is the abbreviation of uninterruptible power supply, which can replace the mains power in an emergency when the power is out, and the power is supplied to the equipment, just like the emergency lighting equipment. However, the design of the UPS system is more precise, which can make the conversion time between the mains and the battery or converter shorter, and make up for the shortcomings of the generator or other emergency power supply interruption time is too long. Because the function of UPS is higher than that of other emergency power supply equipment, it is generally used to protect important equipment, such as computer equipment, monitoring instruments, fire-fighting equipment, and medical equipment.

etc., to meet the strict requirements of computers and various precision instruments for power quality. At present, UPS has been recognized by various high-tech industries and computer circles as the necessary equipment that can truly solve the power supply problem.

2. Why use UPS?

If the uninterruptible power supply system is not used today, then when the mains power is abnormal, it will cause the computer to go down, and even cause hardware failure, and the maintenance cost will be unpredictable; But what about the data that resides in your computer? But money can't buy it, so buying an uninterruptible power supply system for your equipment is like buying insurance.

It must be noted here that the uninterruptible power supply system does not only act when the power is out, and the aforementioned mains abnormality, including the mains voltage is too low, too high, and the peak surge, etc., can suppress the power supply voltage, which is enough to make the equipment operate normally, so the uninterruptible power supply system can bring users a full range of protection work.

3. What kind of equipment is the UPS used for? Is there a limit?

Uninterruptible power system, generally used in the protection of important equipment, such as: computer equipment, precision instruments, medical instruments, etc., because UPS R & D design is based on computers, not all loads are applicable, especially inductive loads, such as electric fans, air conditioners and other household appliances are not applicable, because inductive loads will have back electromotive force, which will cause harm to offline UPS. In addition, equipment with large starting currents such as photocopiers and laser printers can easily cause instantaneous overload if the UPS capacity is insufficient, and the UPS output will also be interrupted when the mains power is interrupted.

When the UPS is overloaded for a long time, it will shorten the life of the electronic components and the UPS.

UPS (Uninterruptible Power System Uninterruptible Power Supply), that is, uninterruptible power supply, is a system equipment that connects the battery (mostly lead-acid maintenance-free battery) to the host and converts direct current into mains power through the host inverter and other module bending circuits. It is mainly used to provide stable and uninterrupted power to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc.

When the mains input is normal, UPS will stabilize the mains voltage and use it to the load, at this time, the UPS is an AC electric regulator, and it also charges the battery in the machine; When the mains power is interrupted (accidental power outage), UPS immediately converts the direct current energy of the battery to the load through the inverter switching conversion method**220V AC power, so that the load can maintain normal operation and protect the load software and hardware from damage. UPS equipment is often protected against either too high or too low voltage.
