Our SG Series 1000KVA 3 Phase Dyn11 Transformer is a premium industrial dry-type isolation power transformer, engineered for global 50Hz/60Hz low-voltage electrical systems up to 1000V. With standard 380V/480V voltage conversion and fully customizable parameters, this Dyn11 isolation transformer delivers reliable electrical isolation and stable voltage regulation, making it the ideal power solution for factory power distribution, CNC machine tools, photovoltaic systems, EV charging stations, precision equipment manufacturing, generator sets, and power transmission facilities. Trusted by electrical engineers and industrial operators worldwide, it is available in SG (enclosed safety cabinet) and SBK (open design) configurations, supporting continuous full-capacity operation under non-overloaded conditions for long-term dependable performance.
Features & Advantages
This 380V 480V isolation power transformer is built with precision engineering and top-grade materials for demanding industrial environments. Its core Dyn11 winding configuration effectively suppresses third-harmonic currents, adapts seamlessly to unbalanced loads, and enhances ground fault protection to minimize equipment damage. It features a high-permeability silicon steel core for ultra-low noise (<55dB), minimal temperature rise (<80K), and low energy loss, paired with high-purity windings for superior conductivity and ≥90% working efficiency. The F-class insulation system withstands 3500V voltage tests for maximum safety, while the advanced porous thermal design extends service life. Additional benefits include zero additional waveform distortion, ±2% output accuracy for sensitive precision equipment, a digital display for real-time voltage/current monitoring, safety trip lock, and high-insulation reliable terminals.
