EI28 type low frequency transformer

The EI28 Low Frequency Transformer is a type of Line Power Transformer,Audio Transformer,Shell Type Transformer,Power Transformers

that are commonly used in various electronic devices and equipment. It is characterized by its compact size and high efficiency, making it suitable for applications where space is limited. The "EI" in the name refers to the shape of the transformer's core, which is typically made of laminated steel sheets in the shape of an "E" and an "I". The number "28" indicates the size of the core, with larger numbers generally indicating larger transformer sizes.

The shell type construction of the transformer refers to the arrangement of the windings and the core. In a shell type transformer, the primary and secondary windings are wound around the central leg of the core, with the core acting as a magnetic path for the flux generated by the windings. This design provides good magnetic coupling between the windings and efficient transfer of power.

Low frequency transformers like the EI28 are designed to operate at frequencies below 100 kHz, making them ideal for power supply applications, audio equipment, and other low-frequency applications. They are typically used to step up or step down voltage levels and provide isolation between different parts of a circuit. The EI28 transformer is known for its high efficiency and low power loss, making it a popular choice for many electronic devices.
