Single Phase to 3 Phase Converter

The SDT series single-phase to three-phase converter, adopted AC-DC-AC circuit structure and using SPWM modulation control technology, which can convert ordinary single-phase power to industrial three-phase power. After through SDT series single-phase to three-phase converter power conversion, the three-phase power output is standard pure sine wave, the harmonic distortion rate(THD) is less than 2%, totally meet the national standards of three-phase power quality, applicable to all types of load.

The SDT series single-phase to three-phase converter can solve production inconvenience because of some areas with the three-phase electric power restrictions, also solved some user requirements that can‚¬ apply for the three-phase electric because of space limitation.


  • Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It’s service life can up to 15 years or more.

  • Pure sine wave output. with good transient response, little harmonic distortion, higher conversion efficiency and stable output voltage features.

  • Adopted low frequency isolated transformer, high conversion efficiency and stable performance.

  • Normal single phase AC grid power input, can Save for three-phase electric red tape and all kinds of artificial cost

  • Safe and reliable, single phase input power is completely isolated from three phase output power.

  • Output AC Power is suitable for all types of home appliances,electric tools, electric motors etc.

  • Converter has the function of filtering the grid disturbance and interference at the same time, which is a good

  • performance of stabilized voltage and frequency power, to providea more stable and pure power supply environment for the backend devices

  • Intelligent fan speed control system, low no-load loss

  • High conversion efficiency, high instantaneous power and low load loss

  • The input voltage,output voltage,frequency and phase can be custom made.

  • LCD display, high efficiency, easy installation.
