Parameter
Latching Mode.
12V output will shut down in the event of an
overtemperature condition or blocked fan rotor.
OT setpoint is 55 ±3 ºC. Supply's fan and Vaux
are active. Power supply will recover when OT
condition is removed. Amber OT LED will turn
ON to indicate fault condition.
Output enable. Pulled low allows V1 to be activated.
For factory use only.

I
High signal indicates AC is within PSU limits.
100 Ohm resistor internally connected to RTN allowing the PSU to be detected on insertion.
Low signal indicates PSU fan is running below speed or an overtemperature limit was exceeded.
High signal indicates both outputs are within regulation limits.
0 to 8V signal used for active current sharing.
I
Two pulses per fan revolution.
Latch-style overvoltage protection. 12V output:
