The core feature of the China EE19 High-voltage single-phase frequency conversion transformer produced by Haoer is that it achieves efficient, safe and reliable high-voltage power conversion and isolation within a very small package. It is the key component for micro-sized high-voltage power supply modules.
The elongated EE19 high-voltage single-phase variable-frequency transformer, without the need for flying leads, can meet the specification certification requirements, significantly enhancing work efficiency.

The high-frequency EE19 High-voltage single-phase frequency conversion transformer produced by Haoer Company are made from high-quality high-frequency soft ferrite magnetic materials, featuring high magnetic permeability, high saturation flux density and low power loss. The products can meet UL, CE, VDE, CQC and other standards according to customer requirements
As applications evolve, so do their core demands on space and energy—progressing from miniaturization to handling significant power draws, and now to achieving energy savings and environmental goals. This relentless drive for improvement centers on optimizing electrical efficiency and expanding functional voltage ranges. Here, high-frequency transformers emerge as a transformative technology, displacing older industrial-frequency models with a compelling advantage: significantly lighter weight, which is absolutely critical for the future of DC electronics.
To harness this advantage, we employ high-performance soft ferrite magnetic materials—known for high permeability, high saturation flux density, and low power loss—in our manufacturing process. We ensure our high-frequency transformers align with your compliance needs, designing for standards such as UL, CE, VDE, and CQC. Our commitment is to provide bespoke design services, offering a versatile selection from multiple product families like EI, EE, EEL, EC, ER, PQ, RM, EFD, EP, EPC, EF, ED, and ETD, crafted to empower your specific applications.
