CZ550Kevlar Posted October 20, 2020 Report Share Posted October 20, 2020 (edited) I'm looking for some McGyver help from the pigeonwatch community. We currently use 110v floodlights powered by a generator on site and these are usually when we are in a MEWP but have a need for spotlights. What we want to do is run 12v vehicle spotlights from a 110v generator, does anyone know of a transformer that will do this? We have found 240v to 12v but can't use 240v on site. Many thanks.

fatchap Posted October 20, 2020 Report Share Posted October 20, 2020 We do a transformer at work that will drop 110-12v but your using car lights which are DC so you would need a transformer with in an inbuilt rectifier. Which we don't do at work. Quote Link to comment Share on other sites More sharing options...

LEDs however.... It would be easier to help you if you could give us some more details! How many spotlights, what type are they, what is their power draw? Surely, if a site is banning you from using 240v, they're unlikely to be happy with jury rigged, high current 12vdc cables kicking about the place? You need a 'power supply' rather than a transformer, as this will include a rectifier, overload protection, and so forth. But I still get the feeling that what you will save over 110v spotlights, you'll lose on having to buy suitably rated cable, connectors, fuseboxes etc, to tie it all together.

Demonic69 Posted October 20, 2020 Report Share Posted October 20, 2020 I've got an old adapter here that takes 100-240v and outputs 12v DC @2A Most PC PSUs will take down to 100v and push out 12V no problem, I've one here with 12A on the +12v rail. As said above, if you can measure the current draw for the lamps it would be easy to figure out a supply. Quote Link to comment Share on other sites More sharing options...
