If possible, help to explain a little more about the UPS knowledge, thank you..
UPS as a protective power equipment, its performance parameters are of great significance, should be our consideration when purchasing. The wide input voltage range indicates that the utilization of electricity is strong (reducing battery discharge). The output voltage and frequency range are small, which indicates that the power regulation capability of the utility model is strong and the output is stable. The waveform distortion rate is used to measure the stability of the output voltage waveform, while the voltage stability indicates the stability of the output voltage when the UPS is suddenly shifted from zero load to full load.
UPS (Uninterruptible, Power, System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply. Used primarily to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately built-in battery power supply to 220V alternating current to the load through the method of inverse transformation, the load to maintain normal working and protect the load of software and hardware is not damaged.
UPS efficiency, power factor and conversion time are all important parameters to characterize the performance of UPS, which determine the protection ability of the load and the utilization rate of the city power. The better the performance, the stronger the protection ability. In general, the off-line UPS has the worst protection to the load, the online interaction is slightly better, and the online type can solve almost all the common power problems. The cost, of course, increases as performance increases. Therefore, when users buy UPS, they should select different types of UPS according to the degree of load on the power requirements and the importance of the load.
Industrial UPS, also called uninterruptible power supply; three three refers to the three-phase power input, three-phase output; it refers to the three-phase power input, single output.
