EI42 Power Conversion Low Frequency Power Transformer Welded Lamination Core

1.Product Description

The EI42 low-frequency power transformer adopts a welded laminated iron core structure, which is precisely pressed from high permeability silicon steel material and designed specifically for 50/60Hz low-frequency environments. This transformer has a rated power range of 50-500VA and a conversion efficiency of over 95%, effectively reducing energy loss. The welding process ensures a tight fit between the iron core, reducing no-load losses while improving structural stability; The special coating treatment enhances the resistance to moisture and chemical corrosion, and can reliably operate within a temperature range of -25 ° C to+130 ° C. The product complies with CE and UL safety standards and is suitable for industrial control power supplies, LED drivers, welding machine modules, UPS, and audio amplifiers. The optimized winding design reduces leakage inductance and improves EMC compatibility, making it an ideal choice for industrial power conversion.
