I have 3 transformers that for some reason burned-out . I say burned- out because that's what it smelled like when they stopped working. If you have a reason why this is happening please include with your instructions on how to repair them if it's possible. These transformers are 120v input ,12v output. Thank You RE
If you put the wrong bulb in they can burn out. You say it's a 12 volt system. There are different wattages, and if you put too high a wattage you will cook the transformer. No, you can't repair them. Not unless you have the machinery to delaminate the metal core, unwind and rewind new copper coils. You COULD do it by hand, but by the time you've gotten it done, the time you wasted could have been spent working and earning a buck to replace the lamps. Make sure you're not going OVER the wattage specified. Here's some numbers: 12 (volts) times X (amps) equals W (wattage). If the transformer tells you it puts out 12 volts at 3300 ma (mili-amps) (or 3.3 amps) then 12 X 3.3 equals 40 (Watts). If your transformer is designed to operate a 40 watt bulb then it must be capable of putting out 3.3 amps. If it's half the wattage, say - 20 watts: 20 / 12 1.67 (amps). Knowing the capabilities of the supply and not demanding more of it than it's rated for will prevent it from smoking (burning out). Hope this helped. '')
