Power Transformer Rectangular Core

High-frequency transformers for auxiliary power supplies of rail transit vehicles, insulated power converters, and inverter welders. High-frequency boosting transformers used in high-voltage power supplies for medical equipment and electrostatic precipitators.

The use of nanocrystalline soft magnetic material with low loss and high saturation flux density reduces the loss of high frequency transformer, and reduce the size and reduce the weight.
