felto Posted February 20, 2006 Report Share Posted February 20, 2006 Hi I just would like to inquire about a coffegrinderthat was given to me from europe. The plug on it was not the standard 110V supply so I changed the plug on it to suit my outlet. Now it still grinds but the problem is that it runs slower. I think I need to change the transformer or something on it. How exactly do I do this and what type of transformerdo I need to install to suit my 110V outlet.Thanks Quote Link to comment Share on other sites More sharing options...
ante Posted February 21, 2006 Report Share Posted February 21, 2006 Hi felto,You need a step up transformer to get this right, how much power (W) does the grinder need? Quote Link to comment Share on other sites More sharing options...
felto Posted February 22, 2006 Author Report Share Posted February 22, 2006 Thanks for the replyIt says that its at 1ma currentand I think 140 watts of power. Quote Link to comment Share on other sites More sharing options...
ante Posted February 23, 2006 Report Share Posted February 23, 2006 Hi felto,Well, I can’t be sure about this because 140W and 1mA does not match by far. I need more specific values to be able to say for sure and not mess up things for you! :-\ Quote Link to comment Share on other sites More sharing options...
felto Posted February 24, 2006 Author Report Share Posted February 24, 2006 Can you tell me what readings are you looking for on the tranformer? I have the unit disassembledand the tranformer is exposed. Where do I hookup my voltmeter and do you need volts, amps or what?Thanks Quote Link to comment Share on other sites More sharing options...
Guest Kasamiko Posted February 24, 2006 Report Share Posted February 24, 2006 Hi Felto..Most devices has some sticker/label printed at the back or bottom of it..The brand..where it is made etc..You can also find there what you are looking for..Just look for some figure with WATTS or W on it..Like:240VAC, 1.0Amp or220VAC, 150Watts220VAC, 150Wsomething like that..Goodluckrhonn ;) ;) Quote Link to comment Share on other sites More sharing options...
MP Posted February 25, 2006 Report Share Posted February 25, 2006 felto,What voltage do you measure at the secondary side of the transformer? It is most likely 1/2 of what you had originally. Another thing to look at is the motor inside this unit. It also should have some markings to tell you what it needs.MP Quote Link to comment Share on other sites More sharing options...
ante Posted February 25, 2006 Report Share Posted February 25, 2006 The maximum power consumption for the unit in watts (W) or (VA) is a good place to start. Quote Link to comment Share on other sites More sharing options...
felto Posted March 10, 2006 Author Report Share Posted March 10, 2006 ok upon further inspecting the unit it says that it uses250V and 1 amp. So where do I go from there?It looks as if the transformer is part of the whole unit and it cant be replaced. Can I add something within thecircuit to let it run at 110V. Maybe a power transistor or something............. Quote Link to comment Share on other sites More sharing options...
ante Posted March 10, 2006 Report Share Posted March 10, 2006 Hi felto,What you need is a step up transformer 110V to 230-250V and rated at least 250VA. Quote Link to comment Share on other sites More sharing options...
felto Posted March 11, 2006 Author Report Share Posted March 11, 2006 Can you tell me what site I can find this step up transformer?Do I just wire it into the other transformer? Quote Link to comment Share on other sites More sharing options...
ante Posted March 11, 2006 Report Share Posted March 11, 2006 Hi felto,I don’t know where you live or where you are able to get stuff from but here are a few links:http://www.happcontrols.com/powersupplies/80004400.htmhttp://www.starkelectronic.com/st500.htmhttp://www.walkabouttravelgear.com/reverse.htmhttp://www.action-electronics.com/trnsupdn.htmYou just put it between the wall outlet and your grinder. ;) Quote Link to comment Share on other sites More sharing options...
SM2GXN Posted March 11, 2006 Report Share Posted March 11, 2006 Hi Felto!Can you take a picture of what you think is a transformer, it would help a lot.If there is a motor inside running at AC the load wont be purely resistive either, we have to take into account or? ::) Quote Link to comment Share on other sites More sharing options...
