December 20, 200619 yr Check it with your tongue. We used to do that with 9v batteries when we were kids. This should be no different - honest (PS. Never thought I'd see the day Wonder Boy was giving advice on TC!)
December 20, 200619 yr I'm with Andy on this, can sense the tears already.... We had an American electric Wok when we came back from Germany, (USAF PX's are amazing......) did all the conversion stuff as told, bu&&er still blew up. Can't you get some uk batts and a charger, probably easier
December 20, 200619 yr If this is the one, stick a 1 amp fuse in it, or you could be changing it a fair bit. This shows the current at just over half an amp. LC3_24_2A_2145_.pdf
December 20, 200619 yr Author It doesn't matter which way round you have the two wires on an AC transformer on the input. That's what I wanted to hear. Measured both blades with a digital vernier and they were both 6.35mm wide, which ties in with what you say above. Fitted a 3amp fuse for now, better than nowt I suppose. Well it works, the little red LED light is lit up on the charger and nowt went bang on the fuse board I got the batteries from a UK supplier and wanted to use the Oset charger as there is a charging port on the bike, this saves hassle having to remove the batteries and charge each one seperately Thanks for all the help (and the p*** taking!)

December 20, 200619 yr It's got some funny fonts in it, but works for me That's the way - calculate the RMS voltage, all the 0.707 junk, then chuck a big nail in it anyway
December 20, 200619 yr Atom do you guys not use GFCI's? Yes but over here they are called RCD's ( Residual Current Devices) but they do the same job.
December 20, 200619 yr Ok, I was just wondering how you guys do it if polarity did not matter. But I think what you meant was in this instance.
December 20, 200619 yr How the **** are you going to get round scotland on that, it will need a long lead.
December 21, 200619 yr How the **** are you going to get round scotland on that, it will need a long lead. If he gets lost he can always follow the lead backwards.
December 21, 200619 yr Problem is that AC/DC transformers are proportional, so with twice the voltage input, you get twice the voltage output! Rectified or not! Unless there is a regulator! You better ck it or you'll burn up the batteries!
December 21, 200619 yr Problem is that AC/DC transformers are proportional, so with twice the voltage input, you get twice the voltage output! Rectified or not! Unless there is a regulator!You better ck it or you'll burn up the batteries! And half the current capacity. In The Geographically Challenged Ones case there will be a regulator, probably switched mode so less heat dissipation.
December 21, 200619 yr caution! putting 220 into the primary will indeed get twice the output voltage intended, but it also may burn out the primary side as the current on that side will be twice as much regardless fof output. Junior may get to see some fireworks. I was over in UK last jan to do some teaching, had to get a 220/110 transformer because laptop power supply died. I ended up at a tool store, (this one was Newbury) and got a power tool transofrmer, 8 inches cubed, I think 1500 w capacity,to run 100w computer. It cost about LS50 I think. Then I patched cables together as you are doing, to get to the plug into my computer. Apparently there are safety rules that outdoor power tools, saws, drills, etc must run on 110 VAC. You might find similar trnasofrmer at industrial suppliers nearby. would still be 50hz though. kcj
December 21, 200619 yr You will probably find the charger is a swithched mode power supply to accomodate that range of input voltages. In which case it wont go pop.
