1、 Product Overview
The DBS series single-phase to three-phase power supply, also known as a two-phase to three-phase transformer or a single-phase 220V to three-phase 380V power supply, uses SVPWM modulation control technology to convert ordinary single-phase 220V electricity into industrial three-phase 380V electricity through rectification, frequency conversion, inversion, and boosting principles. The three-phase electricity converted by the DBS series single-phase to three-phase power supply is a standard sine wave with a harmonic distortion rate of less than 2%, fully meeting the three-phase power quality standards. The output AC electricity is suitable for various household appliances, electric tools, motors, lathes, elevators, frequency converters, compressors and other loads.
2、 Product Usage
The DBS series single-phase to three-phase power supply solves the inconvenience caused to production in some regions due to three-phase power restrictions, and also addresses the needs of some users who cannot apply for three-phase power due to site limitations. Widely used in rural areas, commercial housing, household factories and other places without power (or unable to connect power), wind power and photovoltaic power can also be converted into three-phase power sources for use in farms, field operations and other places.
3、 Main performance characteristics
1. Adopting Mitsubishi's fifth generation high-efficiency IPM intelligent module, the performance is efficient and stable, with powerful protection functions. Short circuit, overload, and over temperature protection are safer and more reliable, with a service life of up to 15 years or more
2. Output pure sine wave, which has the characteristics of transient response less than 50MS, low waveform distortion, high inverter efficiency, and stable output voltage
3. Using a power frequency isolation transformer, the AC bus is completely isolated from the DC bus, avoiding interference between AC and DC
4. Ordinary single-phase mains power input eliminates the tedious procedures and various labor costs of applying for three-phase power
5. The output uses industrial three-phase electricity, but is charged according to civilian single-phase electricity, which has good economic efficiency
6. LCD display, which can display input DC voltage, output frequency, output voltage, output power KWH, time, fault display, etc.
7. The power supply also has the function of filtering out disturbances and interferences from the mains, making it an excellent purification power supply that provides a more stable and pure power supply environment for backend devices
8. Adopting SVPWM spatial vector placement algorithm, high conversion efficiency, high instantaneous power, and low no-load loss conversion The efficiency can reach over 93%.
