    ELV Ring Circuits

    Hi guys.
    Are there anything restricting me making a ring circuit on a 12m × 24V Led tapelight?
    Would appreciate your input.
    Thanks

    I would get the suppliers consent in writing to prevent a come back. Trust me the comeback happens fast with some of the LED tape.Make sure it is mounted onto alu strips as a heatshink
    Majority do not want you to use tails longer than 5m , so I would think you may have a problem.


    I am on a contract at the moment and have left the consultant and preferred supplier to fight out the tail length - They have got to 10m , whereas the design calls for 30m on the longest run

    Its all got to do with the amount of current the PCB track closest to the supply has to handle.
    Usually 1mm of PCB track width can handle 2 Amps of current.
    As you add more and more LED tapes, the PCB track closest to the supply handles the current for its own tape, and for every LED tape that gets added at the end.

    Attempting to make the LED tape width as narrow as possible for cost saving, the track width will nominate the maximum amount of current that it can handle before overheating and burning out like a piece of fuse wire.
