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
* 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
*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
* The input voltage, output voltage, frequency and phase can be
