1.3 Remote On/Off Control

The power supply DC outputs (without +5.0Vsb) shall be enable with an active-highTTL( ≥ 2.5V/2.0mA) -compatible signal(Ps-on). The +5.0Vsb is on whenever the AC

power is present.5.0Vsb TTL Ps-on ≥1.5V/2.0mA ,

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.
