QP29 Industrial High Power Drive Power Supply to Bobbin
                                            The best-selling LED lamp driver transformer bobbin uses Phenolic (Phenolic resin) spars with excellent insulation performance, which can isolate the winding from the magnetic core and prevent leakage. It has strong high-temperature resistance, can withstand the heat generated by the operation of transformers, and is not easy to deform.Moreover, it has high mechanical hardness, which can firmly fix the windings, prevent them from shifting, and extend the service life of the transformer.
