    1 kVA Isolation Transformer, single phase, 240V to 120V

    5 out of 5 based on 1 reviews | Write a review
    Dry type single phase isolation transformer with 1kVA capacity, is design to use in AC circuit 50Hz or 60 Hz, transform 240V primary voltage to 120V secondary voltage. Encapsulation and IP20 protection grade of the enclosure protect the transformer from dust, moisture and provide extra shock and vibration resistance.
    Delivery date: 10-20 days

    The offered 1 kVA isolation transformer is a single phase transformer with lower cost, step up or step down the AC voltage between 240 volt and 120 volt, suitable for hazardous locations as well as harsh industrial environments.

    Tips: Why step up & step down isolation transformer can't convert the DC voltage?

    Alternating current (AC) refers to the current whose voltage and current changes the magnitude and direction with the time. Alternating current is produced by alternator. During the power generation, multiple pairs of magnetic poles are evenly distributed on a circle at a certain angle, so that each coil cuts the magnetic line in power generation. Due to the many pairs of magnetic poles, the voltage and current generated from cutting the magnetic lines of each pair of poles changes according to the string rule, the stable current is thereof produced.

    Operational principle of the transformer is the electromagnetic induction principle. When the primary of a step up & step down isolation transformer connects the AC, an alternating magnetic field is generated in the iron core, the secondary out induces the AC and the induced electromotive force is proportional to the number of turns. If the primary of a transformer connects an DC, the magnetic field produced in the iron core is constant, as a result, no electromotive force is induced in the winding of secondary out, the transformer action will not affect.

    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.
