Source: InternetPublisher:吃掉星星 Keywords: power supply power supply backup power supply Updated: 2021/07/06
Dual power supply auto-turn-on and self-restoration means that one power supply supplies power and one power supply is standby. When the power supply is cut off, the standby power supply automatically goes into operation immediately
. When the power supply is restored, the standby power supply automatically exits and the power supply automatically goes into operation again. . The
circuit is as shown in the figure. Power supply No. 1 is the power supply and power supply No. 2 is the backup power supply .
