STS (System Transfer Switch) provides two power sources for important single power source load withautomatic transfer function, and the load is powered by the main power source when the main powersource is normal When the main power source fails, the load can be automatically transferred to backuppower source quickdy. After the main power source restores to normal, the load can be transferred backto the main power source.
