: q. M; f4 }6 E一个产品标称220-240V, 5600W, 那么产品的额定电流应该怎么算?/ U: B# L: ?7 h4 z( Y, K

1. 230V对应下的额定电流:5600/230 ... & h9 D4 d# f3 M4 _+ O) R4 v

5 r; J& d0 S" R3 { U# o% K" xrated current
1 n% J- T5 U1 vcurrent assigned to the appliance by the manufacturer- k* e9 x$ a5 U3 r& \1 u
NOTE If no current is assigned to the appliance, the rated current is
0 y7 v- H' L j) K: M– for heating appliances, the current calculated from the rated power input and the rated voltage;
4 j$ }; K2 z9 r1 ?( q/ D4 V– for motor-operated appliances and combined appliances, the current measured when the appliance is

这个应该可以算标准支撑吧?既然正常温升可以考虑换算240V, 为什么考虑额定电流的时候就不考虑了呢?有点说不通吧? |
