Talking about the Importance of UPS Uninterruptible Power Supply
Dec 04, 2018

The UPS, that is, the uninterruptible power supply, is an uninterruptible power supply with a constant voltage constant frequency including an energy storage device and an inverter as a main component. Its primary role is to provide uninterrupted power to a single computer, computer network system, or other power electronics. When the mains input is normal, the UPS uninterruptible power supply will supply the load after the mains voltage is regulated. At this time, the UPS uninterruptible power supply is equivalent to an AC mains voltage regulator, and it also charges the internal battery; When the mains supply is interrupted, the UPS will immediately supply the 220V AC power to the load through the inverter conversion method, so that the load can maintain normal operation and protect the load soft and hardware from damage.

In addition, the UPS uninterruptible power supply is used as a protective power supply device, and its performance parameters are of great significance as one of the considerations when purchasing. 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 off-line 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.
