<p>The un-interruptible power supply system comprises an electricity detection device 10 and a power supplying module 30. The electricity detection device 10 is connected to the in-house wiring 11 and detects the state of electricity on the in-house wiring. If an abnormality is detected, a wireless transmitter in the electricity detection device would radiate a wireless signal indicating such an abnormality. A wireless receiver 21 in the power supplying module 30 receives the wireless signal and thereby activates 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. The power supply module may power an electronic device such as a lamp. In addition the UPS system may be associated with a plurality of power supply modules (31a, figure 5) connected to, for example, computers, whilst the detection device is placed in an electric power socket (14a, figure 5) .</p> |
