1. To turn off the output, apply 5 V to the remote On/Off.
2. AC OK is a TTL signal which goes LOW when input falls below
60 VAC at rated load.
3. DC OK is a TTL signal which goes LOW when PSU is in an
overcurrent condition, overvoltage condition, disabled or when
output falls out of regulation.
4. For AC OK and DC OK signals, source current is 1 mA, sink
current is 6 mA.
