Working Principle Of Dual Power Switch

A dual power switch, also known as a transfer switch, operates based on the principle of switching between two power sources to ensure uninterrupted power supply.

 

Here’s how it works:

1.Source Monitoring: The dual power switch continuously monitors the primary power source, such as the utility grid, and the secondary power source, such as a backup generator or battery.

2.Detection of Power Failure: In the event of a power outage or voltage drop in the primary source, the dual power switch detects the loss of power.

3.Switching Action: Upon detection of a power failure, the dual power switch automatically switches the load from the primary source to the secondary source within milliseconds, ensuring uninterrupted power supply to connected devices and equipment.

4.Restoration of Power: Once the primary power source is restored, the dual power switch seamlessly transfers the load back to the primary source, maintaining continuous operation without disruption.

 

In summary, dual power switches provide reliable and automatic transfer of electrical loads between primary and secondary power sources, ensuring uninterrupted power supply and system reliability.
