Power Supply On

Green LED on the PCB

Fan Fail

An open collector output rated for 15V/5 mA sink current maximum.

Goes high if a fan failure is detected

Power Good Signal

Goes TTL high 100 to 500 mS after regulation. Goes low at least 1 mS

before the loss of regulation. Will sink 100 mA.

Remote On/Off

A TTL low signal inhibits the output. Hiccup mode.
