EI35 Power Transformer with Wire Electrical Power Supply Voltage Transformer

1.Product Description

The EI35 power transformer is a compact laminated core transformer commonly used in low to medium power applications (typically 5-50VA). Its "EI" name derives from the stacked E-shaped and I-shaped silicon steel laminations that form its magnetic core, with "35" indicating the approximate 35mm width of the center leg. This cost-effective transformer features primary and secondary windings wound on a bobbin, offering efficient voltage conversion with typical efficiency of 85-95%. The wire-wound version uses enamel-coated copper wire for both windings, allowing customizable turns ratios for specific input/output voltages (e.g., 120VAC to 12VAC). Its robust construction provides reliable performance in power supplies, audio equipment, and industrial controls, with operating frequencies generally ranging from 50Hz to 20kHz depending on core material. The open-frame design requires proper insulation and mounting considerations for safety compliance.

The EI35 Power Transformer with Wire has several significant features. In terms of structural design, the classic EI type iron core with a size specification of 35 is used. This iron core structure has a compact and reasonable magnetic circuit, which can effectively reduce magnetic leakage, improve magnetic coupling efficiency, and reduce energy loss; The high-quality wires used in combination have excellent conductivity, further ensuring efficient and stable power transmission, and reducing power loss during operation.
In terms of performance, it can accurately achieve voltage conversion and provide stable power output for various electronic devices. Whether it is the demand for pure power supply in audio equipment or the requirement for voltage accuracy in small instruments and meters, it can meet all requirements. At the same time, its insulation performance is good, effectively avoiding faults such as leakage and short circuit, ensuring the safety of equipment and users. In addition, this transformer has a wide range of power applications, strong versatility, and can be compatible with various electronic products, making it a reliable choice for power conversion in electronic circuits.
