Usage Method

• When the left side is closed, push up the right side and the left side will be linked to close.
• When the right side is closed, push up the left side and the right side will be linked to close.
• The working principle of the dual power manual switch is to turn off the power first and then switch, so there is no need to worry about short circuit problems.
• It is recommended to choose a 1P or 2P manual transfer switch for household 220V lines, and a 3P or 4P manual transfer switch for industrial 380V lines.

Tips: Automatic Transfer Switch vs. Manual Transfer Switch

A Manual Transfer Switch (MTS) and an Automatic Transfer Switch (ATS) are both devices used to transfer power supply between two sources, such as the utility power grid and a backup generator. However, they differ in terms of operation and functionality.

Manual Transfer Switch (MTS): As mentioned earlier, an MTS requires manual intervention to switch between power sources. The user must physically flip a switch to select the desired power source. This manual operation allows for more control over the switching process, but it also means that someone must be present to make the switch when needed.

Automatic Transfer Switch (ATS): An ATS, on the other hand, is designed to automatically detect power outages or fluctuations in the utility power supply. When it senses a power failure, it automatically initiates the transfer to the backup power source without any manual intervention. Once the utility power is restored, the ATS switches back to the grid and resumes the normal power supply. ATSs are equipped with sensors and control mechanisms that facilitate automatic switching, making them more convenient and suitable for applications where uninterrupted power is critical, such as hospitals, data centers, and critical infrastructure.

In summary, while both MTSs and ATSs serve the purpose of transferring power between sources, an MTS requires manual operation, while an ATS can automatically detect and initiate the transfer based on predefined conditions.
