40KVA Isolation Voltage Transformer | SG Series 3 Phase Industrial Isolation Transformer
Product Introduction
Our 40KVA Isolation Voltage Transformer (SG/SBK Series) is a high-performance industrial-grade 3 phase isolation transformer, purpose-built for reliable power conversion and full electrical isolation in 50Hz/60Hz low-voltage circuits up to 1000V. Designed for global industrial clients including factory operators, precision equipment manufacturers, electrical engineers, and system integrators, this transformer delivers stable, interference-free power for critical applications: CNC machine tools, photovoltaic systems, EV charging stations, power transmission equipment, generators, laser cutting machines, and more. With standard 3-phase 240V input / 400V output, and fully customizable voltage ratios, capacity, and configurations, it is the ideal power solution for demanding industrial environments.
Key Features & Advantages of Our 40KVA Isolation Voltage Transformer
Engineered with premium materials and precision design, our transformer delivers unmatched reliability and performance:
High Efficiency & Low Loss: High-permeability silicon steel core and high-purity copper winding enable ≥90% working efficiency, low temperature rise (<80K), full capacity operation, and minimal energy loss for long-term cost savings.
Superior Isolation & Safety: F-class insulation withstands 3500V voltage tests and 2500V dielectric strength testing, providing complete electrical isolation to eliminate harmonic interference and protect sensitive precision equipment. The SG model features an IP23-rated metal cabinet with safety trip lock, insulated terminals, and input/output indicators for maximum operator safety.
Optimized Heat Dissipation & Durability: Porous heat dissipation design with optional cooling fan reduces operating temperature rapidly, extending service life. It operates with ultra-low noise (<55dB) and adapts to a wide working temperature range of -15℃ to +45℃.
Real-Time Monitoring: Integrated digital display tracks each phase’s input/output voltage and output current, with ±2% output precision for accurate power management.
