The applications of UPS

What is UPS?
UPS stands for Uninterruptible Power Supply, which is an uninterruptible power supply containing energy storage devices. It is mainly used to provide uninterrupted power supply to some equipment that requires high power supply stability. 
When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC-type voltage stabilizer, and it also charges the battery in the machine; when the mains is interrupted (accidental power failure) When the time, the UPS immediately transfers the battery's DC power to the load through inverter switching and continues to supply 220V AC to the load, so that the load can maintain normal operation and protect the load's software and hardware from damage. UPS equipment usually provides protection against over-voltage or under-voltage.

What is the applications of UPS?
UPS uninterruptible power supplies are used in various fields. Uninterruptible power supplies are now widely used in: mining, aerospace, industry, communications, national defense, hospitals, computer business terminals, network servers, network equipment, data storage equipment, emergency lighting systems, railways , Shipping, transportation, power plants, substations, nuclear power plants, fire safety alarm systems, wireless communication systems, switches, mobile communications, solar energy storage energy conversion equipment, control equipment and its emergency protection systems, personal computers and other fields.

Industrial UPS power system, as the basis for the normal production and operation of industrial enterprises, provides reliable power protection for the safe and continuous operation of a large number of advanced industrial production equipment and information systems, and plays a very critical role in these fields.


Problems caused by power quality are extremely common in the industrial field. Especially for the semiconductor industry, it can be said that the quality of UPS uninterruptible power supply is the key to production. Problems such as instantaneous interruption and harmonics will make the entire batch of materials waste, which is costly. For these companies, the quality of electricity used in production is getting closer and closer to the level of the information field.

With the in-depth application of information technology in production, operation, management and other aspects of the industrial field, as well as the large-scale application of high-end and precision equipment, the industrial field has put forward higher and higher requirements for the quality of power supply, which not only requires the continuity of power supply Reliable guarantee, and there are special requirements for the purity of the power supply. In this context, UPS uninterruptible power supplies are widely used in industrial fields due to their high voltage stabilization accuracy and the ability to uninterruptedly provide pure power to the load, providing reliable power guarantee for industrial production and management.

With the rapid economic development, the equipment is also highly likely to suffer from other surge interference from the line (for example, the operating overvoltage phenomenon caused by various power equipment to the power grid when the power equipment starts operation), and its impact on the equipment may be Bigger. Therefore, it is obviously incorrect to simply and intuitively assume that "no overvoltage protection is not needed without lightning". It can be said that the current overvoltage protection work has shifted from the traditional lightning protection to the comprehensive protection of direct lightning, lightning electromagnetic pulse, ground potential counterattack and operating overvoltage.
