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’t apply for the three-phase electric because of space limitation.
Technical Features:
* 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.
*Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the type of their load. This function is very convenient for users and also reduce frequency converter’s usage, which reduced the cost of equipment investment, easy to connect wires and control.
* 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
* 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 provide a more stable and pure power supply environment for the backend devices
* Safety and reliable, the input single-phase electric and output three phase electric is complete electrical isolated.
* Pure sine wave output, has higher efficiency and higher capability of driving load.
*Output perfect protection function, with output over-voltage, overload, short circuit, over temperature, self-diagnosis protection and other protection
* Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
* The input voltage, output voltage, frequency and phase can be custom made.
