The EPC25 High Frequency DC Transformer is a compact horizontal high-frequency power component engineered for industrial-grade ToB applications, belonging to the mainstream EPC-type transformer series with ultra-wide frequency and power adaptability. Designed for high-efficiency power conversion scenarios, this transformer operates at a frequency range of 10kHz~1MHz+ and supports a power rating from <5W up to 500W-1000W, perfectly matching the power demands of small and medium-sized electronic equipment. Beyond serving as a standard flyback/drive/control/inverter transformer, it can also be used as a high-current inductor for switching mode power supplies (SMPS), making it a multi-functional core component for industrial, medical, and consumer electronic systems. The EPC25 features optimized structural design with low energy loss and stable operating temperature, ensuring reliable performance in continuous 24/7 industrial working conditions, and its compact horizontal structure saves valuable PCB space for equipment manufacturers.
The EPC25 High Frequency DC Transformer covers a segmented frequency band from 10kHz to over 10MHz, adapting to the technical requirements of different SMPS and power conversion equipment. Its power range of <5W to 1000W includes all mainstream power grades, eliminating the need for multiple model replacements for customers’ different product lines.
With a low energy loss design, the transformer maximizes output power while minimizing energy consumption, reducing the overall power loss of the host equipment. Its low operating temperature characteristic avoids thermal aging of surrounding components, and stable performance under long-term load ensures a longer service life of the whole machine, reducing the after-sales maintenance cost of ToB customers.
The EPC25 is not only a dedicated high-frequency DC transformer but also a replaceable high-current inductor, realizing the integration of multiple functions in one component. This design helps customers simplify circuit design, reduce the number of components, and lower the production and assembly costs of equipment.
