Product Features
- Single-to-three-phase power supply: Converts single-phase 220V power to standard three-phase 380V power, which is convenient for equipment that cannot access three-phase power.
- High efficiency and energy saving: Using SPWM control technology to ensure that the output is a low-loss sine wave, energy saving and in line with power quality standards.
- Wide input voltage range: Supports input voltages from 180V to 250V, adapting to power fluctuations in different regions.
- Clear display: Equipped with a high-definition LCD screen, it displays input and output voltages in real time and is easy to operate.
- Protection function: The protection indicator lights up when overloaded to avoid equipment damage.
- Soft start: One-button start, smooth start of the device, and avoid current shock at startup.
- Efficient heat dissipation: Built-in fan, effective heat dissipation, ensure stable operation of the device.
- Convenient to move: The bottom is equipped with universal wheels, easy to move the device.
- Safety design: There is a brand circuit breaker on the back to prevent short circuit and explosion, ensuring safe use.
