Fully Automatic Power Transfer ATS Control Cabinet with Unattended Operation and Compact Integrated Design

This ATS (Automatic Transfer Switch) control cabinet automatically switches electrical load between utility mains power and a backup diesel generator. When the mains supply fails or goes out of tolerance, the cabinet signals the generator to start, then transfers the load to the generator. When mains power returns to normal, it transfers the load back and shuts down the generator after a cool-down period.

Designed for unattended operation, this ATS cabinet eliminates the need for on-site personnel during power outages. It is widely used in commercial buildings, hospitals, factories, and residential complexes across Nigeria, Southeast Asia, and other regions with unreliable grid power.
