一篇關(guān)于 SG6561AS+SG6841S 19V/4.74A方案的文章中詳細(xì)敘述了電源的測試項(xiàng)目,其中有幾點(diǎn)是否有重復(fù),請各位分析一下:
1,Dynamic load:Dynamic loading (20% ~ 80% of the full load, 50msec duty cycle)
2,Over shoot & Under Shoot Test:Less than 5% of nominal voltage value,Max. load
3,Turn on time:Load: Max. load & Min. load,AC switch on time: 4Sec max.
4,DC output rise time:Max Load& Min load DC Output rise time: 20mS max.
請大蝦們分析一下以上第1,2點(diǎn)和第3,4點(diǎn)有什么異同???
