Power Transformer

"Smurf" T Series Printed Circuit Board Welded Power Transformer

The "Smurf" T Series fully enclosed epoxy pot-sealed power transformer is characterized by its relatively small size, high power density, and safety performance that meets or exceeds national standards. It can withstand electrical strength of 50Hz 2kV RMS for 1 minute between the windings. Additionally, it is economically priced, making it an ideal choice for producing various consumer-grade products. Its casing is made entirely of sky blue flame-retardant PBT engineering plastic, and due to its compact and robust nature, it earns the name "Smurf."

    Features

    ① A fully-encapsulated printed circuit board is able to be directly welded and assembled, making it easy to use with a perfect outline.;
    ② It is compact in structure, solid, vibration-proof, moisture-proof, flame-resistant, and has high dielectric strength.;
    ③ It has a higher power density with a smaller size.;
    ④ It is economical and affordable,with a competitive price.

    Ambient Conditions

    ① Ambient temperature: -10℃~+40℃;
    ② Relative humidity: ≤90% at 40℃;
    ③ Atmospheric pressure: 860~1060mbar
    (650~800mmHg approximately).

    Insulation Rating

    Class B (130℃).

    Safety Features

    ① Dielectric resistance: >1000MΩ in normal condition;
    ② Insulation withstand voltages: Better than GB/T15290 standard requirements.
    ③ Fire retardancy: In conformity with UL94-Vo;
    ④Insulation impact strength: Continuously 10 times impact of 6KV (50HZ)/50μS;
