Overview
WHK series automatic transfer switch appliances are suitable for power switching in double-circuit power supply systems (grid-grid, grid-generator or generator-generator) due to abnormal voltage or frequency of one power supply, so as to ensure the continuity and safety of power supply for important users. ATSE is widely used in public buildings, energy and civil houses, industrial automation, infrastructure, military facilities and other fields.
