Hi MarkDay

I want to replace the stock transformer in the 110V DC18RA, in order for i to work with 220V. Can you help me find where in europe I can get the transformer needed in order to do this?

    Hi.


    So, since it appears that the DC18RA has a switching supply that simply has a few components only rated for 120 volts, has anyone tried using it on 120 volts AFTER the component change?


    Theoretically it shouldn't make a difference; right?

Hi there the solution for how to mod a DC18RA charger can be found here. The "how to" comes with pictures and descriptions and it should be easy to follow, and best of all it works :)

Don't.

I tried changing the capacitors, but the MOSFET blew instead.  Turns out that the MOSFETs in the 110V model has about half the voltage rating of the one in the 220V model.

The MOSFET is expensive, so you're better off buying a 220/110V transformer or a 220V charger.

Don't replace the transformer in ur charger.just get a step up transformer like 110v to 220volts with plug in receptacle.

    I tried this but it does not work. I'm guessing that the Wattage on the step up adapter has to be higher than the 70W on mine?

I tried this solution. I found out the capacitor has to be bigger. 220uF did not do the job, replaced with 500uF and then it worked :-)

Making my 220v appliance work on an 110v outlet

If you are using a 220V-240V appliance at 110V, you will need a transformer. If you are using a 110V appliance at 220V-240V, you can also use a transformer but may be able to get away with a (cheaper) converter though not with all appliances.

Hi
there are suitable converters in the market from 220v to 110v.
google in your area to find an electronic store that provides this type of converters.
second choice .
if you know someone that winds electrical transformers or motors .you can ask him to modify your transformer its easy done .
number of wire turns and diameter.... turns *2 and diameter 1/2.
for an example: 410 turns for 110v it will be 820 turns and 1/2 diameter of the wire, that will fit exactly the transformer size.
Good luck

If I would buy a Onkyo TX-NR616 in the US (110V) and take it Europe (220V), wouldn't it be a solution to simply exchange the power transformer for a 220v one?

An stepdown transformer is needed should you buy in US and use it Europe

However, if your on a technical side , trace the primary windings , and check

There are European versions which are already 220V, no need to convert.

What is the specific power transformer (internal) i need to switch my logitech 230 speakers from 220v to 110v?

If the speakers are wanting 220V, will they work, at a diminished level, if you only supply 110V ?

Otherwise, you need a "step-up" transformer, which takes 110V input, and produces 220V as output.

Do the speakers have a "110V/220V" switch on them????

The 110v transformer was inserted into 220v socket!

You have damaged the system beyond economical repair. There are so many components inside that have fried that it is impossible to repair. Sorry. That's what happens when you overvolt an electronic circuit.

DC18RA from 110v to 220v

The varistor you have to change is the one that runs parallel on the current after the fuse, in my case it was easy to find as it was the one with the plastic hood on it.

I'm going to update the webpage with some new pictures that I hope would hetp to clarify it.
