如果是这样的电流设置,测试通不过,那这款电源的12V电流虚标,功率也不够700W。
作者的回复:
按照作者的经历来说,上这个电源在3.3V/5V都是1A的时候还是可以启动的。
是在增加到11A/13A的时候fail掉的。
很能说明功率虚标的问题了。
Ron,
The load at 100v for the first unit was 46A 12v 19A 5v and 11A 3.3v (699.3w)
however the unit would not even turn on at that load level. The second unit
from which that data in the article was generated started load testing at
46A 12v, 1A 5v, and 1A 3.3v at which point I began scaling the load up in
order to get to full load. Since the unit failed before full load I just
never changed the values in those columns from my original spreadsheet. The
unit actually failed around 46A 12v, 13A 5v and 11A 3.3v for a total of
655w.
