Feature: 1. [PC Grade Transfer Switch] This is a PC grade infrequent transfer switch, featuring a dual position design (A for the main power source and B for the backup power source). Suitable for AC systems operating at 50 to 60hz. 2. [Main Function] The transfer switch automatically switches to the backup power source (B) when the main power source (A) fails, effectively resolving the issues caused by power outages and ensuring continuous operation. 3. [Ultra Fast Switching Speed] With a switching speed of less than 50 milliseconds, this transfer switch provides instantaneous power transfer, preventing disruption to important systems. 4. [Versatile Installation Options] This dual power transfer switch can be installed vertically or horizontally within a cabinet, offering flexibility and convenience for various applications. 5. [Wide Range of Applications] Ideal for use in homes, office buildings, hospitals, factories, and other environments, this transfer switch provides a reliable solution to ensure uninterrupted power supply.

Package List: 1 x Dual Power Automatic Transfer Switch Note: 1. The working environment temperature range is ‑5℃ to +40℃, and the average temperature within 24 hours should be below +35℃. The storage environment temperature range is ‑25℃ to +55℃, and can achieve +70℃ in a short period of time (within 24 hours).2. When the ambient temperature is +40℃, the relative humidity at the installation site shall not exceed 50%. The lower the temperature, the higher the relative humidity. Appropriate measures should be taken to prevent condensation caused by temperature changes.3. Pollution grade 3 (conductive pollution, or dry non conductive pollution that becomes conductive pollution due to condensation).
