UPS (Uninterruptible Power System), which is an uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply that contains energy storage devices and uses inverters as the main component. Mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. 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 mains voltage stabilizer, and it also charges the battery in the machine; when the mains is interrupted (accidental power failure) At this time, the UPS immediately uses the power of the battery in the machine to continue supplying 220V AC power to the load through inverter conversion, so that the load can maintain normal operation and protect the software and hardware of the load from damage.

UPS is a protective power equipment, its performance parameters are of great significance, and should be the focus of our consideration when purchasing. The wide input range of the mains voltage indicates a strong utilization of the mains (reduce battery discharge). The output voltage and frequency range are small, it shows that the ability to adjust the mains power is strong, and the output is stable. The waveform distortion rate is used to measure the stability of the output voltage waveform, and the voltage stability indicates the stability of the output voltage when the UPS is suddenly added from zero load to full load.

What is UPS it has What functions?

In addition, UPS efficiency, power factor, conversion time, etc. are all important parameters that characterize UPS performance, which determine the protection capability of the load and the utilization rate of the utility power. The better the performance, the stronger the protection capability. Generally speaking, the offline UPS has the worst protection to the load, the online interactive type is slightly better, and the online type can solve almost all common power problems. Of course, the cost also rises with the enhancement of performance. Therefore, when purchasing UPS, users should choose different types of UPS according to the degree of power requirements of the load and the importance of the load.

Under what circumstances is UPS generally used?

UPS is not only used directly on computers, but all equipment equipped with computers (such as medical CT, instrumentation in supply stations, etc.), radar stations, military communication systems, program-controlled telephone systems, surgical operating rooms, etc., all use UPS It is used as a backup power supply instead of a generator.

Application field

Widely used in rail transit, data centers, oil fields, public security, communications, radar stations, electric power, heavy industry, airports, radio and television, banking, securities, and medical systems.
