/ Remote-Inhibit: When vo
ltage level of this pin becomes LOW, it can inhibit the output
of AC Source (see 3.6.1).
AC-ON: When AC Source output voltage, this pin will become HIGH, and it becomes
LOW when quit output.
/ FAULT-OUT: The voltage level of this pin is HIGH if AC Source is in normal state. It
becomes LOW when AC Source is in protection state.
