The 220V to 12V Copper Wound EI Transformer is a single-phase isolation transformer designed to step down mains voltage for low-voltage applications in industrial, commercial, and residential settings. This transformer features EI-type laminated core construction using CRGO (Cold Rolled Grain Oriented) silicon steel, which provides efficient magnetic flux transfer and minimizes core losses during operation. The EI nomenclature refers to the core shape consisting of E-shaped and I-shaped laminations stacked to form the magnetic circuit, with the lamination thickness typically ranging from 0.35mm to 0.50mm depending on the power rating.
The winding construction uses copper conductor material, which offers superior electrical conductivity and heat dissipation compared to aluminum windings, resulting in lower operating temperatures and improved efficiency. The transformer is designed for 50-60Hz operation, covering standard mains frequencies in most global markets. Custom specifications are supported, including various input/output voltage combinations, power ratings, and mounting configurations. The product serves applications including power supplies for control systems, lighting transformers, battery charging equipment, and industrial automation power distribution.
Buyers sourcing this transformer typically include electrical equipment manufacturers, industrial control system integrators, and power distribution product distributors. The supplier indicates flexible pricing with negotiable terms and quick delivery capabilities as competitive advantages. The listing does not specify MOQ, pricing, or lead times, requiring direct communication with the supplier to confirm specific requirements. The product is manufactured in Guangdong Province, China, with customizable specifications to meet diverse application requirements.

Before ordering the 220V to 12V EI transformer, buyers should provide detailed specifications including required VA rating, primary and secondary voltage tolerance requirements, and any special environmental or certification requirements for the destination market. Requesting a detailed quotation with material specifications, dimensional drawings, and test parameters is essential for custom configurations. Verify the supplier's manufacturing capabilities for the specific core size and power rating required, and confirm whether sample production is available for qualification purposes.
Lead time for standard configurations typically ranges from 2-4 weeks, while custom specifications may require 4-6 weeks depending on tooling and material procurement. Shipping terms are typically negotiated as FOB Guangzhou or FOB Shenzhen, with CIF options available for buyers preferring consolidated freight. Payment terms commonly involve T/T with advance payment, though established relationships may support more flexible arrangements. Confirm whether the supplier provides test reports including no-load current, dielectric strength, and insulation resistance measurements with each shipment.
Quality verification should include visual inspection of winding symmetry and termination quality, dielectric testing (hipot test) between primary and secondary windings at specified voltage, and insulation resistance measurement using a megohmmeter. Documentation should include material certificates for core steel and winding conductor, test reports, and certificate of origin. For safety-critical applications, UL or VDE certification requirements should be confirmed with the supplier, as the listing does not specify agency approvals.
