Product Description
32A-125A Dual Power Automatic Transfer Switch (ATS)
The EPEPRO Dual Power Automatic Transfer Switch (ATS) is designed to automatically switch the load between the main power supply and backup power supply, ensuring continuous and reliable power delivery during power failures or abnormal voltage conditions.
The ATS is suitable for AC 50Hz/60Hz electrical systems with rated currents from 32A to 125A. It features automatic transfer, undervoltage protection, phase loss protection, and fire linkage functions, making it an ideal solution for emergency power systems and critical electrical loads.
With a robust structure and reliable switching mechanism, the ATS is widely used in commercial buildings, residential complexes, shopping malls, banks, hospitals, communication facilities, and emergency lighting systems.
