Convert Three Phase 380V To Single Phase 220V Manufacturer

DZW Convert Three Phase 380V To Single Phase 220V

The DZW Three-Phase to Single-Phase Converter Transformer is your ideal solution. It transforms standard 380V three-phase electricity into 220V single-phase power—perfect when you only have access to three-phase supply but need to run single-phase devices.

Whether you’re powering office equipment, industrial tools, or household appliances, this compact unit gives you stable, efficient output with real-time monitoring and built-in protection.

Input voltage: three-phase 380V or 400V or customized
Output voltage: single-phase 220V or 200V or customized

Product Features

⚡ Easy Conversion
Effortlessly convert 380V three-phase to 220V single-phase to run your regular devices—even when only three-phase power is available.
💡 High Efficiency, Low Energy Loss
Thanks to advanced SPWM technology, this unit delivers a clean sine wave output with over 87% efficiency and less than 2% waveform distortion. That means lower electricity bills and more stable performance.
🔍 Smart Display & Monitoring
An HD LCD screen shows real-time voltage, current, and frequency, so you always know what’s going on.
🛡️ Built-In Safety
Overload & short-circuit protection with auto shutdown and alarmSoft start function prevents sudden surges and extends the life of your devicesQuick response time (≤2ms) keeps your equipment protected at all times
❄️ Cool & Quiet
With dual cooling fans and low-noise design (<55 dB), this transformer keeps running smooth—even during long hours of work.
🚚 Portable & Durable
Comes with sturdy wheels and ergonomic handles for easy movement, plus a heavy-duty shell for extra protection.
