Abstract

An automatic power supply control device comprises a control circuit, a timing circuit, a voice circuit and a loudspeaker which are connected between a power supply and a load. The timing circuit is respectively connected with the power supply, the control circuit and one end of the voice circuit, and the other end of the voice circuit is connected with the loudspeaker. The control circuit is an AC (alternating current) contactor, the timing circuit is a microcomputer time controller or a bell ringer, and the voice circuit is a multi-section voice playback chip. Compared with the prior art, the utility model has the advantages of simple structure and low cost, is convenient to use, and can delay to switch off the power supply after a voice prompt prior to the arrival of the timing.
