SIGNAL SPECIFICATION
Pin Assignment Signal Name Description
High Level
Low Level
I Max
D2 P_Good Power good signal output (Internal pull up is 5kΩ to Vsb) >2.4V (active, Good) <0.4V -2 mA +4 mA
A1 +SENSE1
VOUT remote sense, positive node input, connected to the
+ve load point
A2 -SENSE1
VOUT remote sense, negative node input connected to the
-ve load point
A6 PS_ON
Internal 1K ohm pull-up to Vsb, (accepts open collector/ drain
drive), This signal to be pulled low to turn-on power supply
>2.1V (open, or Vsb) <0.7V
(active, PS:On)
-1 mA -4 mA
B5 PS_Kill
Floating pin will turn off P/S (shorter pin, last-make and
fi rst-break contact for hot plugging). This signal overrides
PS-On in disabling the main output
>2.1V
<0.7V
(open, or Vsb) (active, PS:On)
N/A
B6 Present Internally tied to Vsb return 0 V
N/C No Connection
N/C No Connection
N/C No Connection
D1 AC_OK
Input AC Voltage “OK” signal output (Internal pull up is 5kΩ
to Vsb)
>2.4V (active, OK)
<0.4V
-2 mA +4 mA
C5, C6, D5, D6 V_
SB Standby voltage output
There is a jumper already installed between PS_Kill and Gnd .
There is a switch already installed to toggle the PS_ON to Gnd for enabling the power supply.
