    We all Know about Voltage Drop, But do we always take out the Multi-Meter to check?

    Well with this simple $2.50 part off ebay, you can make your own lead an check.
    • About to power inject
      Check each side of the plug to make sure the Voltages are Correct, (The Easy Way)
    • Easy to make, only 3 parts ,mini voltmeter, Rays Plugs, Solder, Heatshrink (3mm black, 6mm white, 16mm clear)
    • Did'nt blow up when Power was Reversed (In my tests :D )
    • Can use one at power supply end, an another one at the last pixel (See real Voltage drop)
    • Apparently there 3v to 30v range (depending on the colour/model)

    Eddy doing current meters with rays plugs might not be a great idea.
    (but it would be great when designing elements to know there current draw)
    Since Rays plugs have been tested around the 5-6amp range.

    Ps. Thanks for the image it makes things allot clearer

    Why wouldn't it be a good idea. Using it for getting the true value current for each output will help people plan their loads better. The unit is rated at 10 amps and Rays plugs will do 5 to 6 amps, so for that purpose I think its a cheap and easy way to make a combined portable volt and current meter that just plugs in line for testing purposes.

    I just bought some for this purpose and am looking at putting one on each line that comes out, So with a 30amp power supply, I will have 3 meters, It may seem to be a bit of overkill, but at least when I decide to add an extra element, i can look at which power supply i can run another lead from without having to look back at diagrams and start working out which light goes where etc. And besides, I don't know of too many people that run 30amp cables from their power supplies.
