    sorry ,a slip of the digit. it's 110v. to 230v. I would really like to remove the internal tx. and replace with 230v. type. The question is what other comps. do I need to consider? i.e. caps. diodes? re. current rating.

The DW9116 is actually a 120 volt charger so it should cope with 130v AC supply, what is the supply from?

It is normal for a standard 110v supply to run at around 117V

See THIS INFO on power supplies

    I did a little hunting and it seems you really want to use your 110v charger on a 230v supply.....



    So you could use a transformer (LINK)



    or you could get a local power supply pack.



    Read the label on back of power pack that attach's to wall socket and charger base, see what input it can handle, some gear can handle like 110v-230v, others cant ie will read 120v



    Any adaptor that puts out the same output as the original would work ie 18v DC 2.5 amps is your specs i beleive so use a transformer or another suitable adaptor



    Please check my quoted specs are the same as listed on power pack of your charge ie I am assuming you are using your 110v A.C. to 18v 2.5amp D.C power pack

    better priced 110/240v or 240v to 110v transformer.



    please note power supplies carry approx 10% + or - so 240 volts copes with 230 v as does 110 v cope with 120 v



    Questions or fixya?



    Cheers

    use a dewalt car charger?



    buy a 240v charger or one is OZ



    So this is your one below, my previous comments re adaptor will not apply if yours has fixed cord and you want to use the 110v version in 230v land then in that case you will have to go with the either the transformer, car adaptor 12v option, or a new 240v version, Do not plug in your 110v adaptor in 230 otherwise it will leak smoke.

    exact model of charger is?

  • Soulvisitor
    Soulvisitor Jan 30, 2008

    Cannot give you components need to make it a 230v unit, the rectification circuit (board on left)will require replacement. The charge circuit would remain the same. You tell me the value of all components that are in the circuit and I tell you the new values, but it would be wisest to use correct model for correct supply

    I think it is a switch mode power supply, cant just flick over transformer, you would need to mod entire circuit, will need full circuit diagram and it would end up not economical to do

Where are you getting 130Vac from?
The proper thing to do is get a Variac which is a variable ratio transformer which can step the 130 down to whatever you want. A 10 amp one will cost about $90 though. They last forever though, so you might get one much cheaper on EBAY.
Actually, the chargers for stuff like cordless drill batteries are switcher types that can tolerate quite a wide range of input voltages. Some can go all the way from 110 to 220. Does yours have a spec for the input range? Even if it has a tight range it will probably handle 130V.

I bougth reciprocating saw, model BJR 182Z and circle saw, BSS611Z while I was in the U.S.A.These tools use the 18 volt LXT Lithium-Ion battery BL 1830. I also bought this battery.However I am going to use...


Why can't you buy the 230 volt DC18RA charger in europe (amazon.europe country) and use it. I had the same issue yet i burned out the fuse in the 110 volt DC18RA charger because i plugged it into the wall just using an adaptor. Lesson learned. Therefore, my first solution was that i bought a converter from 220V-to 110 Volt. This showed me that my charger was done. So instead of getting another 110 volt charger sent here to Europe from Canada, I returned the converter and have on order a 230 volt input DC18RA charger from amazon.de which has the same 7.2-18V output. I have been told this will work yet the fear, and I don't know why, is that it will burn out the batteries in a year or so. It is difficult getting specific information from Makita, but I hope it all works out. Best of Luck for you

Convert 2 pin dewalt charger to 3 pin how


By 3 pin do you mean the third pin being a ground. If so that charger does not have anything internal to ground to. It is a 120Volt Double insulated tool. Let me know if you are trying to do something different.
