UPS (Uninterruptible Power System), that is, an uninterruptible power supply, is an energy storage device.
Uninterruptible power supply, constant voltage constant frequency uninterruptible power supply with inverter 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 supplies the mains voltage to the load for use. At this time, the UPS is an AC mains voltage regulator, and it also charges the internal battery; when the mains is interrupted (accident blackout) At the same time, the UPS immediately supplies 220V AC power to the load through the inverter conversion method, so that the load maintains normal operation and protects the load soft and hardware from damage. As a protective power supply device, UPS power supply has important performance parameters, which should be the focus of our purchase. A wide range of mains voltage input indicates strong utilization of utility power (reducing battery discharge). The output voltage and frequency range are small, indicating that the power supply adjustment capability 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 suddenly loads from zero load to full load. UPS efficiency, power factor, and conversion time are all important parameters that characterize UPS performance, which determines the protection of the load and the utilization of the utility. The better the performance, the stronger the protection. In general, the offline UPS has the worst protection against the load, the online interaction is slightly better, and the online type can solve almost all common power problems.
