Mechanical Details
PSKILL : This Must be tied to 12V stand by return to turn on V1.
ACOK : Open Collector Signal.
Low = Input ≥85VAC.
High = Input ≤75VAC.
PWOK : Open Collector Signal.
High = Power is good.
Low = Power not good. (when any output
voltage falls below regulation limits).
PRFL
: Open Collector Signal.
High = Fan is not operating within limits.
Low = Fan is OK.
FAIL
: An Open Collector Signal.
High = Power Supply Failed.
PRESENT# : This signal is connected to the Low = Present.
12V RTN inside the power supply. High = Not Present.
Pull up to VSB located in system.
FANC : Accepts an input voltage from the system.
FANC < 1V, fan in sleep mode.
2V < FANC < 3.0, fan in low speed.
3V < FANC < 10.5, fan ramps from low to high speed.
FANC > 10.5, fan in high speed.
