What is Sander UPS and how to use itUninterruptible power supply is a constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as the main component. Mainly used to provide uninterrupted power supply for a single computer, computer network system or other power electronic equipment. When the city power input is normal, UPS will supply the city power to the load after stabilizing the voltage. At this time, UPS is an AC city power regulator, and it also charges the batteries in the machine. When the city power interruption (accident power outage), UPS will immediately supply the power of the battery in the machine to the load through the inverted conversion method to continue to supply 220V AC, so that the load can maintain normal work and protect the software and hardware of the load. Damaged.
UPS as a protective power supply equipment, its performance parameters are of great significance and should be the focus of consideration when we choose to purchase. Wide input range of municipal voltage indicates strong utilization ability of municipal power (reducing battery discharge). The small range of output voltage and frequency indicates that it has strong ability to adjust municipal power and stable output. 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 UPS suddenly increases from zero load to full load.
Moreover, UPS efficiency, power factor and conversion time are all important parameters to characterize the performance of UPS, which determine the protection capacity of load and the utilization rate of electricity. The better the performance, the stronger the protection capability. Overall, offline UPS has the worst protection for load, online interactive mode is slightly better, and online mode can solve almost all the common power problems. Of course, the cost increases with the performance. Therefore, when purchasing UPS, users should select different types of UPS according to the different requirements of load on power and the importance of load.
