18kW 1 Phase to 3 Phase Converter, 110V to 220V

The 18kW single phase to 3 phase converter efficiently converts single-phase electricity into stable three-phase AC power for industrial applications. It produces pure sine wave output with THD ≤2%, stable voltage, and precise 120° phase angle, ensuring reliable motor performance. Equipped with SVPWM control and high-performance IPM modules, the system achieves conversion efficiency up to 94% with low no-load loss. The converter supports 80–320V AC wide voltage input, customizable output voltage and frequency, and includes LCD monitoring and complete protection functions for safe and stable operation.

Note:

1. When the load is a motor, the phase converter should be more than 5~7 times the motor capacity.
2. When the load is soft start + motor, the phase converter should be more than 3 times the motor capacity.
3. When the load is VFD + motor, the phase converter should be more than 1.5~2 times the motor capacity.
