+V4(+5.0V) ≤100 mS ≤100mS
+V5(+5.0VSB) ≤50 mS ≤50 mS
Note: The output voltages shall rise from10% to 90% of their output voltage.
輸出從10%上升到90%的時間
1.3 Remote On/Off Control:(遙控功能)
The power supply DC outputs (without +5.0Vsb) shall be enable with an active-high
TTL(≥2.5V/2.0mA)-compatible signal(Ps-on). The +5.0Vsb is on whenever the AC
power is present.
除5.0Vsb 外,其余輸出受控于一個TTL 電平兼容的信號(Ps-on≥2.5V/2.0mA),
5.0Vsb 上電就存在。
* When Ps-on is pulled to TTL high, the DC outputs are to be enabled.
Ps-on 高電平,打開輸出
* When Ps-on is pulled to TTL low or open circuit, the DC outputs are to be disabled.
Ps-on 低電平,關(guān)閉輸出
