Product Introduction

Our 250KVA 380V To 220V Step Down Voltage Transformer (SG Series) is a high-performance industrial-grade 3-phase dry-type power solution, engineered to deliver precise, stable voltage step-down conversion from 380V to 220V for global industrial and commercial applications. Compatible with 50/60Hz electrical systems, this transformer supports full-capacity continuous operation, with ±2% output precision and no additional waveform distortion, making it the ideal power choice for factory power distribution, AI data centers, CNC machine tools, laser cutting machines, photovoltaic systems, EV charging stations, medical equipment, and precision instruments. Trusted by electrical engineers and industrial operators worldwide, it ensures reliable power supply for even the most demanding 24/7 loads.

Key Features & Competitive Advantages

Precise Stable Step-Down Conversion: Delivers consistent 380V to 220V voltage reduction with ±2% output precision, no additional waveform distortion, and 4% short-circuit resistance, perfectly matching sensitive industrial equipment and precision devices.
High-Efficiency Energy-Saving Design: New high-permeability silicon steel core enables noise-free (＜55dB) operation, ultra-low energy losses, and ≥90% working efficiency, drastically cutting long-term operational electricity costs.
Superior Electrical Safety & Insulation: High-purity winding material delivers strong conductivity and low temperature rise (＜80K); Class F insulation, 3500V di-electrical strength withstand, and ≥5MΩ insulation resistance ensure maximum operational safety.
Rugged Durable Construction: Customizable IP23/IP44/IP56/IP64 protection enclosure, reliable high-insulation terminals, safety trip lock, and premium nylon insulation frame guarantee long service life in harsh industrial environments.
Smart User-Friendly Design: Digital display for real-time working status monitoring, input/output indicators, optimized heat emission holes, convenient wiring structure, and brake-equipped universal wheels simplify installation and maintenance.
