Notes & Conditions
Uncomitted opto isolated transistor, normally off when AC is good (see fig.9 - 11)
Provides ≥ 5 ms (typically 20-30ms) warning of loss of output from AC failure
Uncommited isolated optocoupler diode, powered diode inhibits the supply (see fig.12-17)
Isolated 5 V/0.5 A supply, always present when AC supplied.
