Product Overview
Our 5.5KVA 6KVA Single Phase To Three Phase Transformer (Model DSG-5.5KVA) is a compact, high-performance power conversion device, engineered to reliably convert single-phase 220V grid power into stable pure sine wave three-phase 380V power (fully customizable voltage and capacity including 6KVA). Adopting advanced AC-DC-AC conversion technology, it differs from variable frequency drives for motor speed regulation, delivering clean power that closely matches ideal AC power with stable frequency, constant voltage, and zero waveform distortion. Built with a microprocessor core, MPWM mode, and IGBT modules, it integrates digital frequency division, instantaneous value feedback, and isolation transformer output for enhanced system stability. It perfectly solves three-phase power access challenges in remote areas or sites without three-phase grid coverage, making it ideal 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 suitable for sensitive precision instruments and all types of industrial loads.
- Efficient Cooling & Long Lifespan: Porous heat dissipation with cooling fans rapidly reduces operating temperature; high-purity winding material ensures high conductivity and low temperature rise, paired with a noise-free silicon steel core for high magnetic flux and energy savings.
- Comprehensive Safety Protection: F-class insulation, high-insulation materials withstand 2500V voltage tests, with a safety trip lock, short-circuit, overcurrent, and overheat protection; high-quality nylon frame and insulated terminals ensure 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 enable flexible mobility, and IP23 metallic enclosure with customizable RAL 7035 color ensures long-term durability.
- High-Efficiency Performance: ≥90% working efficiency, <55dB ultra-low noise, stable operation in -15℃ to +45℃ environments, with <60K temperature rise for continuous duty.
