The un-interruptible power supply system mainly contains an electricity detection device and a power supplying module. The electricity detection diction is connected to the in-house wiring and detects the state of electricity on the in-house wiring. If abnormality is detected, a wireless transmitter in the electricity detection device would radiate a wireless signal indicating such an abnormality. A wireless receiver in the power supplying module would receive the wireless signal and thereby activate auxiliary power provisioning. As such, the present invention is able to accurately maintain product operation as long as the power provisioning from the in-house wiring is normal, and to sustain the power provisioning precisely when there is a black out. |
