  • Hammond Toroidal Isolation 120vac To Plug In 178 Series - China

    price: contact company for price

    Due to the superior magnetic properties of Toroidal transformers they

    will be susceptible to high magnetizing current when initially

    energized, only limited by the low DC resistance of the primary winding.

    Depending on where you are in the AC cycle when the transformer is

    energized dictates the chances of overloading the supply circuit.

    This

    is why the transformer may sometimes energize without a problem and

    other times it will blow the fuse or trip the circuit breaker.

    The

    duration of this overload is rarely longer than a half of a cycle.

    Therefore, you should consider using a slow- blow fuse, time delayed

    circuit breaker or other form of soft start circuitry for the supply

    line when using these high efficient Toroidal transformers.
