For emergency power in buildings,Auto Transfer System (ATS) is essential. ATS can
automatically transfer load from main power to emergency power without operator's
operation. When the main power fails or voltage drop below 80% of normal voltage,
the ATS will start emergency generator set after a preset time from 0 to 10 seconds
(adjustable).At rated speed, the ATS will transfer load to emergency power with
available from 40A to 4,000A. There is a SWT ATS that can meet every project's need.
