BZT-8KW Single phase to three phase converter

BZT series Power phase converter, adopted AC-DC-AC circuit structure and SVPWM modulation control technology, which can convert ordinary single-phase power to industrial three-phase power. Two phase to three phase ,3 phase to 3 phase and so on.After through BZT series power phase converter power conversion, the output is standard pure sine wave, the harmonic distortion rate (THD) is less than 2%, totally meet the national standards power quality, applicable to all types of load.

Technical Features:

1) Using the sixth 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.

2) 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.

3) Pure sine wave output with good transient response less than 50ms, waveform distortion is very little, higher conversion efficiency and stable output voltage.

4) Adopted low frequency transformer which ensure the input voltage and output voltage are completely electrical isolated to avoid interference.

5)Using the SVPWM space vector algorithm, high conversion efficiency, high instantaneous power and low no-load loss conversion efficiency can reach more than 94%, no-load loss is small.

6) Output AC Power is suitable for all types of electric appliances, electric tools, electric motors etc. higher capability of driving load.

7) 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.

8) Output perfect protection function, with output over-voltage, overload, short circuit, over temperature, self-diagnosis protection and other protection.

9) High conversion efficiency, high instantaneous power and low load loss.

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

11) DC input optional.
