UPS Power Supply

UPS (Uninterruptible Power Supply) is an energy storage device. Primarily composed of energy storage units and inverters, it delivers constant-voltage and constant-frequency uninterrupted power.
When the mains electricity operates normally, the UPS regulates the voltage and supplies power to the load, while charging its built-in battery simultaneously. Once a mains power failure occurs, the UPS instantly converts power from the internal battery via the inverter and continues to output 220V/380V AC to the load. This ensures the connected equipment runs steadily and prevents damage to its hardware and software.
Working Principle
With normal mains input, the UPS stabilizes grid power for the load and charges the integrated battery pack. In the event of a power cut, it immediately converts battery power to 220V AC and feeds it to the load without interruption, safeguarding the equipment’s hardware and software.
