DeWalt charger DW9116

[arneh]

Hello.

I have purchase'd a DeWalt combo kit in the US.
In this kit there was a charger DW9116.
I live in Denmark, we have 230 V current in the US the current is 110 V
I have send't mail to DeWalt to ask if this charger can be used on 230 and 110 V but they say no...
I se here in europ DeWalt sell a charger called DE9116 that is simular to the DW9116 the only difference is proberly that on work on 110 V and one on 230 V.

Then I think the parts cant be that different, and change som part in the charger cant be that difficult if only I know which parts ?

So my question for you are : Anyone know if it is posible to change som parts in the DW9116 charger so it will work whit 230 V ?

Hope som can and will help
Tanks

The easiest and safest solution is a 230~110V step-down transformer. 110V powered DeWalt chargers are not mains isolated, so are tricky to work on and could be lethal if incorrectly modified.

Does it use a transformer, or a switching power supply? If it's a transformer and you don't want to use an external step-down transformer, you could simply swap the 110v transformer to a 220v one with the same voltage on the secondary winding as the original one.

after det cord I can se a fuse, then there is a LFU1005V3 see : http://www.delta.com.tw/product/cp/inductor/line_filters/download/pdf/LFU1005V.pdf

And then som diode and so on

So is the lfu1005V3 a transformer that transform the current from 110 V to something ...

the part you listed is described as a filter not a transformer for stepping down voltage.......

If the charger is switch mode based, the usual way to develope the main supply is either full bridge rectification of the incoming supply(230v ac ) or use the bridge and capacitors to provide a voltage doubling of the 110 v ac supply....

I can se som parts that I think have somting to do whit the power of the charger:

F1 E39 FQP (or EQP) 16N25

and a 18 pin chip
