Product Overview
Our 2 Phase To 3 Phase Voltage Transformer (Model DSG-20KVA) is a professional AC-DC-AC conversion power supply, engineered to convert single-phase 220V grid power into stable, pure sine wave three-phase 380V power for global industrial and commercial applications. Unlike variable frequency drives for motor speed control, this DSG series transformer uses a microprocessor core, MPWM technology, and IGBT modules, with digital frequency division, instantaneous value feedback, and isolated transformer output for enhanced stability. It perfectly solves power supply needs in remote areas or sites without three-phase grid access, with strong load adaptability, full protection functions, and wide compatibility for hospitals, factory power systems, CNC machines, laser cutters, blenders, photovoltaic systems, EV charging stations, and precision equipment worldwide.
Key Features & Advantages
- High-Precision Stable Output: Delivers ±2% output accuracy with no additional waveform distortion, producing pure sine wave power that closely matches ideal AC power, suitable for all types of inductive and resistive loads.
- Efficient Cooling & Long Lifespan: Porous heat dissipation with cooling fans rapidly reduces operating temperature; new low-noise silicon steel core offers high magnetic flux and energy savings, while high-purity winding material ensures high conductivity and low temperature rise.
- Comprehensive Safety Protection: F-class insulation, high-insulation materials withstand 2500V voltage tests, with a safety trip lock, short-circuit, overload, and overheat protection, plus high-insulation terminals and nylon frame for maximum safety.
- Smart Monitoring & User-Friendly Design: Digital display provides clear real-time working status tracking, with input/output status indicators, brake-equipped universal wheels for flexible mobility, and IP23 protection metal enclosure with customizable RAL 7035 color.
- High-Efficiency Performance: ≥90% working efficiency, <55dB low noise, stable operation in -15℃ to +45℃ environments, with <60K temperature rise for long-term continuous use.
