Product Description
The dual power automatic switching switch is a switch of two power supplies.It is divided into common power supply and standby power supply.When the common power supply is cut off, the backup power supply is automatically powered.After the common power supply is restored, the power is switched to the common power supply.If you do not need automatic conversion in special cases, you can also set it to manual switching.
Only when the power supply is available, the switch will switch to the standby power when the common power supply is cut off.Common power can be municipal power, while the standby power can be solar power generation, street lamp power, battery power or any other AC power source of 110V/220V. (The common/standby power supply should be AC 110V/220V power supply. If it is DC or low voltage power supply, you need inverter to become AC 110V/220V).
For Example:
Many households are equipped with energy-saving and environmentally-friendly solar power. We can use solar power as a common power source and the home grid as a backup power source. When the solar power is sufficient, solar power can supply us with a household's power for a period of time.
When the solar power is used up, the switch will automatically switch to the home grid power supply. After the solar power is restored, the switch will automatically switch to the solar power supply by default, and disconnect the grid power!
