Single phase 220V to 3 Phase 400V AC Power Source for 3 phase AC induction motor
Single Phase to 3 Phase Converter EinführungSANDI SDT series Power Phase converter is one of the most advanced AC to AC conversion products in the world which can convert ordinary single-phase power to industrial three-phase power.It has the main advantages of high quality sine wave AC output, microcomputer control, humanness design, highefficiency, low no-load loss and no pollution.
The converter 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 Features
1) The input voltage, output voltage, frequency and phase can be custom made.
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 sixth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency andstable performance. It with powerful protection function for short circuit, over load, over temperature. Service life can reach 15-20 Jahre.
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) Adopts new magnetism material, largely reduce machine consumption, making efficiency maximum up to 98%.
8) Adopts America DSP chip, safe and reliable.
9) Adopts black pure aluminum radiator, which confirms the best radiating performance
10) 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
11) Intelligent fan speed control system, low no-load loss
12) LCD display, high efficiency, easy installation
13) Der output frequency 50Hz/60Hz can be set
