What is a Rapid Shutdown Device?
In the rapidly growing world of solar energy, safety remains a top priority. As solar installations become more common on residential and commercial rooftops, understanding the components that keep th
automatic transfer switch is a PC class infrequent change-over switch,with two- station design (commonly used for A and standby for B), suitable for ACsystems with AC 50-60hz and rated current 6A-63A. The main function of theautomatic transfer switch is when the main power (common power supply A)fails, the ATS will automatically switch to the backup power (Backup powersupply B) to continue working (switching speed <50 miliseconds), which caneffectively solve the troubles caused by power outages.
