220V To 380V Single Phase To Three Phase Transformer | SHLEIPUSI OEM/ODM Manufacturer
Product Introduction
Our 220V To 380V Single Phase To Three Phase Transformer (DSG Series) is a professional AC-DC-AC conversion inverter power supply, distinct from variable frequency controllers for motor speed regulation. Its core function is to convert existing 220V single-phase grid power into stable, pure sine wave three-phase 380V power, delivering near-ideal AC performance with consistent frequency and voltage. It is the perfect replacement for remote areas or sites unable to access three-phase grid electricity, serving global customers including factories, CNC machine tools, laser cutters, photovoltaic systems, diamond cutting equipment, precision instruments, residential users, generator manufacturers, and blenders.
Key Features & Advantages
Built with a microprocessor core and advanced MPWM technology, our DSG series uses high-performance IGBT modules, digital frequency division, D/A conversion, instantaneous value feedback, and sine pulse width modulation, supporting single-unit capacity up to 300KVA. Isolation transformer output enhances full-machine stability, with strong load adaptability and premium output waveform quality.
Core benefits include:
- Full-capacity operation with low temperature rise, low energy loss, and energy-saving design
- High-permeability noiseless silicon steel core and high-purity windings for superior conductivity
- Comprehensive protection: short circuit, over-current, overload, overheating, and safety trip lock
- Digital display for real-time working status monitoring and clear data reading
- Efficient porous heat dissipation with cooling fans to extend service life
- Heavy-duty high-insulation terminals for safe wiring and reliable conductivity
- Compact, lightweight design with brake-equipped universal wheels for flexible use
- ISO9001, CE, UL certified, compliant with global environmental and safety standards
