Led Driver 200w 12v Dc Transformer 15.5v 220v To 48v Transformer 4000w Ferrite Ec28 Transformer

EC28 high frequency transformer is one of the core components of switching power supply, it has three functions of energy transmission, voltage conversion and electrical isolation. The working frequency of high frequency transformer is usually 20-100KHZ. At the same time, we can also customize products with various frequencies according to customer needs. Our products are widely used in CNC equipment, home appliances, communication equipment, office equipment, instrumentation, photographic equipment, air conditioners and smart equipment.
High-frequency transformers have two energy transmission modes in switching power supplies: one is transformer transmission mode, and the other is inductive transmission mode. The transmission mode of the transformer is the same as that of the ordinary power frequency transformer. A certain voltage is applied to the primary to transmit the electrical energy from the primary to the secondary of the transformer; the transmission mode of the inductor is to use the principle of inductance energy storage to apply a voltage to the primary for a certain period of time to generate excitation. The current magnetizes the magnetic core of the transformer, and converts electrical energy into magnetic energy and stores it in the magnetic core of the transformer. When the excitation current is interrupted, the electromagnetic induction phenomenon causes the secondary to generate current, and the magnetic energy in the transformer core is converted into electrical energy and transmitted to the secondary. Solve your application and needs in different scenarios.
