50kW digital phase converter from Single Phase to Three

Phase Converter

SANDI SDT series power phase converter, adopted AC-DC-AC circuit structure and using SVPWM 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 5%, 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:

• The core components are all imported, adopting the sixth generation IPM module from Mitsubishi, which has stable performance, long service life, strong protection functions and convenient replacement and maintenance.
• Adopt the central processor DSP28335 chip from American TI Company, respond quickly and accurately, and provide stable and clean power for the load to provide protection.
• 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.
• The whole machine adopts modular design and plug-in design, which is convenient for maintenance and reduces the hidden cost of machine failure to repair.
• Pure sine wave output with good transient response, little harmonic distortion, higher conversion efficiency and stable output voltage features.
• Using SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses conversion efficiency up to 88%.
• Output AC Power is suitable for all types of three phase appliances, electric tools, electric motors etc. It has higher efficiency and higher capability of driving load.
• Converter has the function of filtering the mains disturbance and interference, it’s a stable frequency and stabilizing voltage with excellent performance, to provide a more stable and pure power supply environment for the back-end equipment.
• Humanized safety design, using isolation transformer design, input and output are completely electrically isolated, input and output are equipped with circuit breakers, which saving costs for the user and easy to installation, the electric parts are completely closed to prevent electric shock.
• Complete output protection function, with multiple protections such as output over-voltage, overload, over-temperature, short-circuit, self-diagnostic protection.
• LCD + LED display, can display input and output voltage, current, KWH, fault display, convenient for customers to quickly find faults and guide maintenance.
• The input voltage range and output frequency 50HZ or 60HZ can be set. Over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point all can be setting via the LCD panel.
• The input voltage, output voltage, frequency and phase can be custom made.
