Pin
Number Pin
Name Description
1 (A1) PS_KILL 3.3V st-by output controll pin, short to GND at server
2 (A2) +12V_CS Current share - for balance load between paralell PSU
3 (A3) GND Logic/controll ground
4 (A4) 3.3V 3.3V Stand-By output
5 (A5) A0 I2C device adress bit 0 select
6 (A6) 3.3V 3.3V Stand-By output
7 (B1) GND Logic/controll ground
8 (B2) spare PWM input for fan speed controll
9 (B3) GND Logic/controll ground
10 (B4) 3.3V 3.3V Stand-By outpu
11 (B5) SDA I2C bus DATA signal
12 (B6) PS_ON Main 12V output controll pin
13 (C1) GND Logic/controll ground
14 (C2) Tach1 Open collector fan speed signal
15 (C3) GND Logic/controll ground
16 (C4) 3.3V 3.3V Stand-By output
17 (C5) SCL I2C bus CLOCK signal
18 (C6) VG AC input presents and above minimum level
19 (D1) Present Power supply seated
20 (D2) spare Logic/controll ground
21 (D3) GND Logic/controll ground
22 (D4) 3.3V 3.3V Stand-By output
23 (D5) S_INIT/ALERT 3.3V Stand-By output
24 (D6) POK Power output OK
Warning: Controll interface was 3.3V only. Do not connect to 5V circuit.
Pin number Description
Power output pins: PB1 GND return for main output
PB2 GND return for main output
PB3 GND return for main output
PB4 +12V main output
PB5 +12V main output
PB6 +12V main output
看到SCL\SDA数字接口说明启动电源是通过它们传输指令的，仔细查查其它接口是否有模拟控制口。 A1和B6都接地就可以。 PS_ON-PS_KILL短接就可以输出了
