    Tips: ATO Step up & step down isolation transformer shell selection

    The selection of the shell is also very important to the isolation transformer protection and it should be according to the requirements of protection and the using environment, so the shell forms are diversified. Conventionally, the ATO step up/down single phase and three isolation transformer shell selects IP20 mainly to protect the live parts and to prevent the cats and rats as well as some larges and 12mm diameter foreign matters into the transformer, which may cause short-circuit and other serious accidents. In addition, the outdoor transformer protective shell needs to select IP23, which not only has the above functions, but also can avoid droplets within vertical 60 degrees. However, this will have an impact on the cooling capacity of the isolation transformer, so the operation capacity needs to be paid attention to.

    How to Test Step Up & Step Down Isolation Transformer?

    Need more detail of ATO isolation transformer? Here is a good explanation about it in this video. To test the accuracy of the transformer voltage, we take a 3000 VA single phase 220V iuput to 110V output isolation transformer as an example.

    Existing reviews of 8 kVA Isolation Transformer, 480V 3 phase to 240V 3 phase
    Does what it says, good value
    Ordered this 8 kVA isolation transformer to use an appliance from Korea in the USA. As far as the value of the unit is concerned, I'm very pleased with the purchase. This unit appears to be quality and will last quite a while.
