SPECIFICATION
3.2.2. Remote on / off:
The PSU DC output ( except for the +5Vsb ) shall be enabled with an active-high, TTL
compatible signal ( " PS-ON " ), the +5Vsb 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 circuited, the DC outputs are to be disabled.
* The DC output enable circuit shall be SELV compliant
3.2.3. Over-shoot:
Any over-shoot at initial turn-on and turn-off must be less than 10% of nominal voltage
value.
3.2.4. Turn-on delay time: 2 sec. Max. @ 120Vac/60Hz
3.2.5. Rise time:
The output voltage should be rise from 0 volt and settle within regulation in less than 30 ms
( measured at T1 ) firm apply of nominal AC input voltage.
3.2.6. Hold up time:
5ms typical at full load applied to the output, 115Vac / 60Hz and 100% power down at zero
crossing on the AC input.
3.2.7. Response time:
All outputs return within ±5% of nominal voltage within 5m sec. For a 50% load change.
