The invention relates to a UPS (Uninterruptible Power Supply) device, comprising a UPS circuit and a commercial power supply circuit and further comprising a multiplexing button, wherein the UPS circuit is connected with one end of the multiplexing button, and the commercial power supply circuit is connected with the other end of the multiplexing button through an optical coupling isolation circuit; when commercial power is input in the commercial power supply circuit, the multiplexing button is closed so that the UPS circuit provides a safe signal for the commercial power supply circuit through the optical coupling isolation circuit, and the safe signal is a signal in a specified threshold; and when no commercial power is input in the commercial power supply circuit, the multiplexing button is closed so as to trigger the UPS circuit to supply power to the commercial power supply circuit.
Description
Technical field [0001] The present invention relates to power technology, in particular to an uninterrupted power supply device and a working method thereof. Background technique [0002] UPS (Uninterruptable Power Supply, uninterruptable power supply) is a power supply that can continue to supply power to equipment after a power failure. It mainly plays two roles in computer systems and network applications: one is emergency use, to prevent sudden power failure from affecting normal work and causing damage to the computer; the other is to eliminate power surges, instantaneous high voltages, and instantaneous lows on the mains. "Power pollution" such as voltage, wire noise and frequency deviation can improve power quality and provide high-quality power for computer systems. [0003] Generally, four buttons can be set on the interface of existing UPS products, and one of these four buttons is individually set as a battery cold start button. [0004] Since the total number of buttons...
