Note:
The output voltages shall rise from10% to 90% of their output voltage.
1.3 Remote On/Off Control
：
The power supply DC outputs (w5.1Vsb) shall be enable with an active-high
TTL(
≥
2.0V/2.0mA)
-compatible signal(Ps-on). The +5.1Vsb is on whenever the AC
power is present.
* When Ps-on is pulled to TTL high, the DC outputs are to be enabled.
* When Ps-on is pulled to TTL low or open circuit, the DC outputs are to be disabled.
