Product Features:
⚡ Easy Conversion
Easily convert 380V three-phase to 220V single-phase, allowing you to use regular single-phase devices even when only a three-phase supply is available.
💡 High Efficiency, Low Energy Loss
Using advanced SPWM technology, this transformer delivers a clean sine wave output with over 87% efficiency and less than 2% waveform distortion, leading to lower electricity bills and more stable performance.
🔍 Smart Display & Monitoring
An HD LCD screen shows real-time voltage, current, and frequency, keeping you informed about the transformer’s status and performance at all times.
🛡️ Built-In Safety
This transformer features overload and short-circuit protection, auto shutdown, and an alarm system. A soft-start function prevents sudden power surges, extending the lifespan of your devices. The quick response time (≤2ms) ensures that your equipment is always well-protected.
❄️ Cool & Quiet Operation
Equipped with dual cooling fans and a low-noise design (<55 dB), this transformer runs smoothly even during extended operation periods.
🚚 Portable & Durable
Designed with sturdy wheels and ergonomic handles for easy movement, along with a heavy-duty shell to provide extra protection for the unit.
