Customized Copper Ring Transformer for High-Fidelity Audio

Pure Copper Performance for 220V/240V Systems For audio amplifiers, the quality of the winding material dictates the quality of the sound. This Customized Ring (Toroidal) Transformer utilizes high-grade copper ("cooper") windings to minimize resistance and heat, ensuring a silent noise floor and dynamic headroom. Specifically designed for 220V and 240V input markets (UK, Europe, Australia), it provides clean, stable step-down conversion to 12V or 24V outputs. The ring-shaped core further reduces magnetic flux leakage, making it the preferred choice for audiophile-grade power supplies.

Green Technology & Broad Reputation We understand that modern manufacturing must be responsible. We sell our goods well and gain broad reputation from clients not just for our scale, but for our commitment to environment-protection products. Our dedication to efficiency and sustainability was formalized when we established a green electronic illumination R&D center qualified by district and city levels in 2009. This focus on "green" engineering ensures that your audio transformer is both energy-efficient and built to last.

 
 

Rigorous Material Control To guarantee the purity of the copper and the integrity of the core, we do not rely on external suppliers alone. NRE possesses a dedicated material center within our test complex. Here, we conduct strict material examinations before production begins. Furthermore, our environmental testing facilities subject the transformers to harsh conditions, ensuring they perform reliably in diverse climates.

 
 

Award-Winning Manufacturing Choose a partner recognized for excellence. NRE was titled as a Guangdong Private High-tech Enterprise in 2008. We consistently promote product quality management through our unique culture building, ensuring that every customized unit meets the highest standards.
