Automatic Transfer Switches

ETEK Solar automatic transfer switches (ATS) automatically monitor utility grid parameters and switch critical loads to a backup generator or inverter within milliseconds upon power loss, returning to the mains supply once electricity stabilizes. Equipped with integrated micro-controllers, precision voltage and frequency sensing, and reliable dual-source interlocks, our automatic changeover devices protect critical circuits without requiring manual operator intervention.

Engineered for high electrical endurance and strong short-circuit withstand ratings, ETEK Solar ATS switches are widely deployed in commercial buildings, data centers, hospitals, communication stations, and modern solar-plus-storage microgrids. Available in PC-class and CB-class modular designs, they provide intelligent, unattended power continuity and robust system protection across global electrical networks.
