Product Description

1ph to 3ph inverter 

SANDI 1 phase to 3 phase inverter is the most advanced AC-DC-AC type converter products, which can convert ordinary single-phase power to industrial three-phase power. It has the main advantages of high quality sine wave AC output, multi-function, stable and reliable performance, set up parameters flexibly, easy for maintenance and long service life 15-20 years. It can meet different user’s different requirements. 

1ph to 3ph inverter can supply AC power to all kinds of electric equipment, electric motors, pump, compressor, and other industrial power supply. Applicable to all types of load.

Technical Feature:

1) The input voltage, output voltage, frequency and phase can be custom made.

1ph to 3ph / 2ph to 3ph / 50hz to 60hz power phase converter

2) Two kinds of start mode: Step Down Voltage Start and Variable Frequency Start. VFD is especially used for taking 3 phase inductive load more easily. 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.

3) Output AC Power is suitable for all types of home appliances,electric tools, electric motors etc.

4) Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function for short circuit, over load, over temperature. Service life can reach 15-20 years.

5) Pure sine wave output. with good transient response, little harmonic distortion, higher conversion efficiency and stable output voltage features.

6) Adopted low frequency isolated transformer, safe and reliable, single phase input power is completely isolated from three phase output power, high conversion efficiency, high instantaneous power, stable performance and low load loss.

7) 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 back end devices

8) Intelligent fan speed control system, low no-load loss

9) LCD display, high efficiency, easy installation

10) The output frequency 50Hz/60Hz can be set
