What is AC Voltage rating of your electric item?
Your item's voltage rating should fall within these three groups:
-
A100-240Valso known asDual Voltage -
B120Vor110-125V -
C230Vor220-240V
-
-
Determine the power requirement for your item (WATT)
Instructions:
If your item doesn't have the watt rating then calculate it by multiplying AC voltage x Amp rating.
-
A23W -
B220V - 500mA -
C240V - 1.8A
- *Fairly simple, as 'W' is clearly stated in this case 23W.
- Calculate W = V x A, and 1000 mA is 1A so in this case 220V x 0.50A = 110W
- Calculate W = V x A, so in this case 240V x 1.8A = 432W.
*Note you may find a range of wattage rating, i.e 1200W - 2000W on an item so in that case select the MAX wattage rating.
