CPM 280 Series - 6000 Watt Transformer


The 280 series is designed around the ER51 planar ferrite core with an Effective Area of 348mm^2. A circular centre-leg helps reduce the mean turn length of windings. The unique core shape of the ER51 and our choice to keep the winding stack contained within the ferrite core ensures better EMI performance for our customers. Customers can also look forward to reduced winding loss, leakage inductance and component length. Various core heights and materials are available, allowing higher power-density Transformers and Inductors within the same Series. The last of the Low-Medium power range parts (typically 6000 Watts), the 280-Series are regularly designed using a combination of PCB and Copper Stamped windings. Both winding types are catered for by our library of stocked Copper and PCB windings allowing us to create your desired turns ratio and power throughput.
