The power supply efficiency shall be greater than65% under rated input voltage. It will be measured at the typical load and maximum load.

在额定输入电压，最大负载和额定负载条件下，电源的效率大于65%。

The upper and lower limits of the rated power input or rated current shall be marked on the appliance so that the relation between input and voltage is clear.

额定输入功率或额定电流的上限值和下限值应标在器具上，以使得输入功率与电压之间的关系是明确的。

These transactions were very complex internally, but externally one can see quite simply that these select few constructed a money machine that took mortgages, a large percentage of which were junk, as input and put out mortgage backed securities that were rated AAA. Plus, these money machines insured the transactions as though the mortgages were top rated (a 2% default rate, as I recall).

FORBES: Hang it up, Wall Street. Dodd-Frank is here to stay
