2PCS 2 Channel Automatic Power Switching Module Automatic Emergency Power Supply Module Switch Dual Power Supply Module AC 90-240V 10A Backup Battery Switch Controller Module

The function of the dual power 220V automatic switcher module is to realize automatic switching of two power sources. The main power supply is connected to the common main power supply, and the auxiliary power supply is connected to the backup power supply. The output power voltage is equal to the input power voltage. When the main power supply has no voltage output,the module automatically switches. It is the backup power output. When the main power supply is restored, the module automatically switches to the main power output. Note: When the main power supply is energized, the backup power supply is not turned on, and the power is supplied by the output of the main power supply; when the main power supply is cut off, the backup power supply is automatically turned on, and the backup power supply is powered by the output of the backup power supply; The main power output provides power.
