ccokeman Posted February 22, 2015 Posted February 22, 2015 L should be positive and N for negative L should = Load N should neutral Share this post Link to post Share on other sites More sharing options...

jasonlylevene Posted February 22, 2015 Posted February 22, 2015 It might help to have a brand / model of the device. For this kind of thing you really need a digital multi-meter. You say you tried, but it burnt your fingers. Tried what, exactly? Share this post Link to post Share on other sites More sharing options...

paulktreg Posted February 22, 2015 Posted February 22, 2015 So for the 48V DC output they are using a standard 3 pin IEC mains connector like you'd plug into a PC power supply? Fairly sure that would be verging on illegal in the UK. The L & N stand for live and neutral but these are AC terms. It could be wired any way really but common sense would make L positive and N negative but you need a multimeter to confirm. Who's the maker and what's the model number?

Waco Posted February 23, 2015 Posted February 23, 2015 http://www.axiomenergy.co.in/48V_3AE-bike_charge.html Should be -24v on one side, +24v on the other side, and a ground in the middle. Use your DMM to confirm which side is which. Share this post Link to post Share on other sites More sharing options...
