Our 400V To 200V Step Down Voltage Transformer (SG Series) is a Dyn11 configuration industrial isolation transformer, engineered for stable, high-efficiency voltage step-down conversion in global 50/60Hz low-voltage electrical systems. Manufactured in Shanghai, China, this standard 100KVA three phase transformer delivers reliable 400V three-phase input to 200V (or 230V customizable) output, making it the ideal power solution for factory power distribution, CNC machine tools, photovoltaic systems, EV charging stations, laser cutting machines, air compressors, precision equipment, generators, and power transmission devices. With a robust metal enclosure, digital monitoring system, and comprehensive safety features, it meets strict international industrial standards, with full customization of capacity, voltage, protection rating, and appearance to fit diverse project requirements worldwide.
Key Features & Competitive Advantages
High Efficiency & Energy-Saving Performance: Built with a high-permeability low-noise silicon steel core and high-purity winding material, it delivers ≥90% working efficiency, ultra-low energy losses, low temperature rise (<80K), and <55dB quiet operation during continuous full-capacity running, cutting long-term industrial power costs.
Superior Safety & Isolation Protection: Featuring Dyn11 isolation design, high-insulation reliable terminals, premium nylon insulation frame, and safety trip lock, it withstands 3500V voltage tests and 2500V 1-minute di-electrical strength tests without breakdown. Class F insulation and customizable IP23-IP64 protection ensure safe operation in harsh industrial environments.
Precise & Stable Power Output: It guarantees ±2% output precision with no additional waveform distortion and 4% short-circuit resistance, providing clean, stable power for sensitive precision equipment and diverse industrial loads.
Smart Monitoring & User-Friendly Design: Integrated digital display with input/output indicators enables real-time working status monitoring. Porous heat emission holes with optional cooling fan deliver efficient heat dissipation to extend service life, while brake-equipped universal wheels and convenient wiring terminals ensure flexible deployment and easy maintenance.
