    24V dc lighting circuit

    I am having a flat roof constructed with solar panels over. As it is a cold, vented flat roof I will be having 175mm of Cellotex insulation immediately above the ceilings which I am reluctant to dig into to fit downlights (which I have never been the world's biggest fan of anyway). My thoughts...

    I've got 24V computer fans, but the output for the fan power ports are 12V, and I'm trying to figure a way to it connect them to my computer. The other problem is that the fans only have two wires compared to the four-pin ports inside my computer, so is there also a way to convert them to the...

    Calculating volt drop on 24v, supplying LED lights.

    I'm getting a little confused about volt drop and 24v. I want to fit an LED strip light. 8m of lights 7w/m. It would be easier to have the 24v driver approx 10m from the beginning of the strip of the LED strip. I'm not sure where to start to know if this will work without any effect on the...

    Connecting a 24V supply to some crimped wires

    Hi All, This is probably a very straightforward question, but I'm a bit confused about what I actually need to do this. I have a device that came with a 12 pin connecting cable (unwired) that is used for data transfer and power. I can deal with the data cables, but the 3 wires for the power...
