Product Description

SANDI SDT-40KW phase converter single phase 220VAC to 380V 3 phase output


Product Introduction

The Sandi SDT series three-phase to single-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 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 limitation.


Technical Features:

  • Using the sixth generation efficient IPM intelligentmodule 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: Step Down 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.
  • Intelligentized, modularized, simple structure design, very easy andconvenient for maintenance.
  • The output frequency 50/60HZ can be setting via LCD panel, it’s very convenient for customer.
  • The output voltage can be set between -40 % to +20 % of rated voltage. And the output voltage is very accuracy ±1%.
  • Pure sine wave output. With good dynamic responseless than 50MS, waveform distortion rate smaller, higher conversion efficiency and stable output voltage.
  • Built-in low frequency isolation transformer, strong impact resistance, available with motors, pump, air conditioners and other high impact equipment.At the same time DC busbar and AC busbar are completely isolated to avoid interference.
  • Using SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses conversion efficiency up to 94%.
  • Powerful data display and fault instruction 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 code display.
  • 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 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.
  • Output perfect protection function with under-voltage and over-voltage, overload, short circuit, over temperature, self-diagnosis protection and other protection.
  • There are lightning protection device inside the converter.
  • Optional DC inputfunction to supplement the AC energy deficiencies.
  • Wide voltage input 80-320VAC, can also customize the special voltage according to the requirements, to adapt to the working environment of the regional grid voltage is low.
