四、 Pin Connection
連接器腳位定義:
Table 4 PIN-CN2 Connection And Function
NO. | Pin Connection | Function |
1.2.3.4 | GND | output RETURN |
5.6.7.8 | +24V | +24VDC output |
Note: TYPE PITCH 2.54mm
Table 5 PIN-CN3 Connection And Function
NO. | Pin Connection | Function |
1.2 | +12VDC | +12VDC output |
3.4.5.12.13 | GND | +12/+5/+5STB RETURN |
6.7.10.11 | +5VDC | +5VDC output |
8 | +5STB | STANDBY(+5.0V)OUTPUT |
9 | PS-ON | On/off control (on =high) |
Note: TYPE PITCH 2.54mm。
Remote on/off control 遙控功能: The power supply DC outputs (without +5STB)shall be enable with an active-high TTL(≥2.5v/2.0mA)-compatible signal(ps-on). The +5STB is on whenever the AC power is present.
除+5STB外,其餘輸出受控於一個TTL電平兼容信號(PS-ON≥2.5v/2.0mA),+5STB上電就存在.
When ps-on is pull to TTL high ,the DC outputs are to be enable.
PS-ON 高電平,打開輸出.
When ps-on is pull to TTL low or open circuit ,the DC outputs are to be enable.
PS-ON 低電平或開路,關閉輸出.

1 | L | AC INPUT LINE |
2 | NC | NO CONNECTED |
3 | N | AC INPUT NUTRUEL |
Note: TYPE PITCH 3.96mm。
