    AC current regulater ACR

    Has any one seen a circuit that regulates or limits AC current.
    That is overall current used.
    Uses a Trac or SCR in its design. This is for a transformer or Motor.

    I wish to adapt it so it has adjustable current limit.

    If depends on what you want.

    Do you need a constant current source or just over load protection?

    For now I'll assume you need overload protection.

    If it's <50VAC then you can get Poly switches (PTC resistors) which go high impedance when an overload is encountered.

    At higher voltages you'll need to use a circuit breaker, most are manula reset but you can buy ones that auto reset.

    I do not answer private messages asking for help because no one else can: benefit from advice I may give or correct me if I'm wrong.

    Please ask on the open forum if you have a question and I'll be happy to help,
    if I know the answer.
