1. The EDR Shape Core Single-Phase Power Transformer produced by Haoer Factory is generally composed of two "mountain" shaped magnetic cores located above and below the frame. They are matched with the frame through slots. This structure helps to reduce the thickness of the transformer, giving it an ultra-thin appearance, which is suitable for installation on power boards with strict height limitations.
2. Usually, there are primary windings and secondary windings, which are wound respectively on the winding columns on both sides of the frame. The windings are generally made by interlacing copper foils or using other winding methods suitable for high-frequency transmission to enhance the performance and efficiency of the transformer.
3. The main features of EDR are its small size, easy installation and low temperature rise.
4. EDR is widely used in LED lighting and electronic devices.
The high-frequency transformers 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
The evolution of electronic devices has driven a parallel shift in spatial and energy demands: from initial miniaturization, through a phase of high power consumption, to the current era prioritizing energy efficiency and environmental sustainability. This progression reflects an industry-wide pursuit of excellence, particularly in enhancing electrical conversion efficiency and expanding operational voltage ranges. A landmark innovation in this journey is the widespread adoption of high-frequency transformers, which have superseded bulky industrial-frequency counterparts. Their substantially reduced weight and superior performance render them indispensable for the future of DC-powered electronics.
Our company specializes in the manufacturing of high-frequency transformers utilizing advanced soft ferrite cores, distinguished by their high magnetic permeability, high saturation flux density, and minimal core losses. We engineer our products to comply with major international safety standards, including UL, CE, VDE, and CQC, tailored to client specifications. Offering comprehensive custom design services, our portfolio encompasses a wide array of core shapes such as EI, EE, EEL, EC, ER, PQ, RM, EFD, EP, EPC, EF, ED, and ETD to meet diverse application needs.
