Power Transformer

"Silver Angel" SL Series Flat Printed Circuit Board Welded Power Transformer

The "Silver Angel" SL Series flat closed epoxy pot-sealed power transformer is distinguished by its excellent electromagnetic characteristics and high input overvoltage capacity. It features an internal temperature protector that can effectively cut off the power supply and prevent equipment burnout even in the event of a short circuit in the transformer load. The transformer is adaptable to a wide range of environments, boasting a sleek appearance, low installation height, compact structure, and excellent moisture-proof, flame-retardant, and high electrical strength properties. It is easy to use, with the capability to change the connection mode to achieve different input and output combinations. The casing is made of silver-gray flame-retardant PBT and PBO engineering plastic. With its outstanding safety performance, it is the best choice for customers producing industrial-grade equipment and military-grade products.

    Features

    ① The fully-encapsulated printed circuit board can be directly welded and assembled, and has a perfect outline.
    ② It has a low mounting height, compact structure, and is solid, vibration-proof, moisture-proof, flame-resistant, and has high insulation withstand voltages.;
    ③ It is easy to use and reconfigure, and alternative input/output voltages can be obtained by changing the connections of the primary and/or secondary. 
    ④ It has a built-in temperature protector, making it safer to use.

    Ambient Conditions
