Product Overview

Defon Electronics manufactures toroidal power transformers designed for high-efficiency power conversion in industrial, commercial, and high-reliability applications.

Compared with traditional EI transformers, toroidal power transformers use a ring-shaped core structure that significantly reduces magnetic leakage, improves energy efficiency, and minimizes vibration and acoustic noise.

Our toroidal power transformers are widely used in industrial equipment, automation systems, medical devices, audio systems, renewable energy systems, and OEM power supply units requiring stable and clean power output.

We support full customization in voltage, power rating, insulation class, shielding, and mechanical design to meet global industrial requirements.
