2.3 TIMING / HOUSE KEEPING PS_ON PS_OFF DC Enable 95% 10% PWR-OK T2 T4 T3 * PW-OK sense level : 95% of nominal 2.3.1 REMOTE ON/OFF CONTROL The power supply DC outputs (with the exception of +5VSB) shall be enabled with an active-low, TTL-compatible signal("PS-ON"). The +5VSB is on whenever the AC power is present. . When PS-ON is pulled to TTL low, the DC outputs are to be enabled. . When PS-ON is pulled to TTL high or open circuited, the DC outputs are to be disabled.
