Product Overview



 System principle:

The inverter power supply after AC→DC→AC conversion is called single-phase to three-phase power supply, which is different from the variable used for motor speed regulation.Frequency control controller. The main function of the single-phase to threephase power supply is to convert the existing AC grid 220V into three-phase 380V power.Electric sine wave power supply. The ideal AC power supply is characterized by stable frequency, stable voltage, internal resistance equal to zero, and pure voltage waveform.Sine wave (no distortion). The inverter power supply is very close to the ideal AC power supply, so it can completely replace the remote area or cannot apply.Please ask for the three-phase area, but the output power of the single-phase to threephase power supply is determined by the 220V current of the mains. DZW series Phase-to-phase three-phase power supply, with microprocessor as the core, MPWM mode, designed with active component IGBT module, adopted Digital frequency division, D/A conversion, instantaneous value feedback, sinusoidal pulse width modulation and other technologies, so that the stand-alone capacity can reach 400KVA,Isolation transformer output to increase the stability of the whole machine, with strong load adaptability, good output waveform quality, easy operation and volume Small, light weight and other features, with short circuit, over current, overload, overheating and other protection functions to ensure reliable operation of the power supply.


Single-phase three-phase power supply, general-purpose direct / direct-current circuit structure, SPWM control technology used, general single-phase three-phase power for industrial use. Single-phase conversion three-phase power conversion after three-phase power standard sine wave, phase angle 120 °, tsunami loss rate small 2%, full-fledged national three-phase power mass standard, application in various types. Single phase three-phase power supply solution for three-phase electric power supply due to inconvenient three-phase electric power production, inconvenient, three-phase electric power supply demand for three-phase electric power supply.

 Technical characteristics:

1.Ordinary City Electricity Import, Ministry of Application Three-phase Electric Prosperity Procedures and Various Artificial Compositions.

2.Three-phase electricity for industrial use, but single-phase electricity for civil use

3.The core of the machine, the performance, the service life length.

4.Safely available, import single-phase electricity supply and export three-phase electricity complete gas isolation.

Q 1. what's the payment term?  

A. We accept TT,30% deposit and 70% balance against copy of BL.

 Q 2. how's the delivery time ?

A. usually it will take about 7-20 days for production. For sample usually in 1 week.

 Q 3. Tell me the standard of package?

A. For the small capacity, color box as inner package and carton as delivery package. For big capacity, use strong wooden case for protection.

 Q 4. What kind of material of transformer?

A. For servo type stabilizer, we have two types, one 100% copper and the other is copper with aluminum. It depends on your requirement . In fact, those two have no difference if normal work well. Only except the longlife. Copper is better and also higher price. For relay type stabilizer,we use toroid coils, the material is aluminum. comparing with square coils, toroidal coils with high efficiency.

 Q 5.Could you offer Form A or C/O ? 

A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.

 Q 6.Would you accept to use our logo ?

A.Our logo is ZX. If your order,has good quantity,

it absolutly no problem to do OEM.

But you use our logo ZX will be high appreciated.

 Q 7.We want to know month capacity. 

A. It depends on which model.For example for relay type small capacity , month capacity can reach near 10000pcs   and big capacity near 2000pcs.

 Q 8.Where is your market?

A. Our products are popular inNorth America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europeand so on.Some of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.

 Q 9. what kind of certificate you have ?

A. Our company already obtained CE , ISO9001,PCT,SGS. design and technical patents certificates.
