POWER SYSTEM FOR ACTIVELY MAINTAINING OPERATION

摘要

A power system for actively maintaining operation includes a power supply unit electrically connected to a commercial power source, a back panel electrically connected to the power supply unit and an ON/OFF control unit. The power supply unit has an OFF state and an operating state to convert the power provided by the commercial power source for outputting. The back panel converges the output of the power supply unit and provides a driving power. The ON/OFF control unit has an input detection terminal electrically connected to the commercial power source to detect whether the commercial power source supplies power and at least one operation signal terminal to output an operation signal upon judging that the commercial power source supplies power to drive the power supply unit to enter the operating state.
