The China EFD Single-Phase Horizontal High-Frequency Transformer produced by Haoer features a very low structural height, high transmission power, low leakage flux, and wide application range.
Spécification : EFD15 / EFD20 / EFD25 / EFD30 / EFD40, etc.
1. The EFD transformers utilize flat ferrite cores, and their shape possesses unique structural advantages. The flat design of these transformers results in a smaller size in the height direction, effectively saving installation space. They are particularly suitable for applications in electronic devices with strict space requirements.
2. A multi-layer winding structure is typically employed to achieve excellent electromagnetic coupling and electrical performance. The windings are generally made of high-purity copper wire, which has low resistance and can reduce energy loss, thereby enhancing the efficiency of the transformer. Additionally, the design of multi-layer windings can be flexibly adjusted to vary the turns ratio according to different application requirements, enabling various voltage conversion functions.
3. Performance characteristics of EFD type transformer: Wide operating frequency range, high power density, high efficiency, and stable electrical performance.
4. The EFD type transformer is used in switching power supplies, inverters, medical electronic equipment, air purifiers, mosquito repellents and plasma circuits.
