120/240V Dual Input Voltage Converter with low frequency isolation transformer

BANGZHAO BZT series single-phase to three-phase converter, adopted SVPWM modulation control technology, which can convert ordinary single-phase power to industrial three-phase power. After through BZT 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. 


Application for voltage converter:

Single phase voltage to three phase voltage, two phase voltage to three phase voltage, the voltage and frequency does not match, the voltage and frequency output instability and other fields.

Technical Features for Bangzhao BZT Series voltage converter

1. 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.

2. Optional function:DC input(Suitable for input power shortage, use direct current to supplement)

3. The 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.

4. The wide Input voltage range design, to adapt to the regional general electricity voltage is low working environment

5. The phase angle of 120 °, The harmonic distortion rate of less than 2%, fully meet the national power quality standards for all types of load.

6. Safe and reliable, single phase electric input and output three-phase electric complete electrical isolation
