Note: The output voltages shall rise from10% to 90% of their output voltage.
1.3 On/Off Control (ON/OFF
The power supply DC outputs 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.
5.0Vsb
* When Ps-on is pulled to TTL high, the DC outputs are to be enabled. Ps-on
* When Ps-on is pulled to TTL low or open circuit, the DC outputs are to be disabled. Ps-on
