Vertical EI Transformer Silicon Steel Sheet EI28 Low Frequency Power Transformer

1.Product Description

The EI28 Low Frequency Power Transformer is a compact and efficient transformer designed for low-frequency applications, typically operating at 50Hz or 60Hz. It features an EI28 laminated core, made of silicon steel, which minimizes core losses and ensures high magnetic efficiency. This transformer is widely used in power supplies, audio equipment, and other electronic devices requiring voltage conversion or isolation at low frequencies. Its robust construction, reliable performance, and cost-effectiveness make it a popular choice for industrial and consumer electronics.

2.Characteristic

1. Performance aspect
--Low no-load loss: High quality silicon steel sheets with low power consumption, such as H18, H23, H50, Z11, etc., are used to effectively reduce energy loss during no-load operation.

--High efficiency: By using pure copper enameled wire and silicon steel sheets, combined with advanced CNC fully automatic wiring and fully automatic silicon steel sheet automatic bonding technology, the utilization rate of the iron core is improved, thereby enhancing the working efficiency of the transformer.

--Low temperature rise: High quality materials and advanced production processes reduce the heat generated by transformers during operation, resulting in a lower temperature rise, which is beneficial for extending the service life of transformers and ensuring their stable performance.

--Low noise: On the one hand, the material and manufacturing process of silicon steel sheets help reduce the noise generated by magnetostriction; On the other hand, fine control during the production process, such as uniform winding of windings, also reduces noise caused by mechanical vibrations and other factors.

--Good insulation performance: It can be encapsulated with epoxy or other methods, and has the functions of moisture-proof, waterproof, and dustproof. It can effectively prevent external factors from damaging the internal insulation of the transformer. The electrical strength between windings can withstand 50Hz, 3750V effective value/1 minute.

--Good adaptability to grid voltage: The product parameter design fully considers the fluctuation range of grid voltage. When the domestic grid voltage is generally between 170V and 265V, it can work normally and meet the usage requirements of different regions.

2. Structure and installation aspects
--Beautiful appearance: A fully sealed V0 grade PP flame-retardant engineering plastic protective jacket, with a frame made of V0 grade PBT brand new engineering plastic, which is safe and beautiful, and can effectively prevent damage.

--Easy installation: The lead pins can be directly soldered onto the PCB, and the pin positions adopt a unified standard pin position, such as the EI-35 unified standard pin position, which is convenient for upgrading and expanding the control board and products in the future. It is easy to use and has multiple installation methods such as pin type, bracket type, and direct insertion type.
