WK310 15HP/11kw boost Frequency inverter single phase 220V converter to three phase 380v AC power transformer for motor VFD
Type selection instructions:
1. Please read the product instructions carefully, choose the type according to the function and power you need, and avoid the damage caused by wrong wiring.
2. This frequency converter can not drive other load types except inductive load such as motor . Please pay special attention to it when purchasing.
3. The overload capacity of 220V to 380V frequency converter is small. Please choose at least one higher power level. When the load is very large (such as gear pump hydraulic pump) or there is a blocking condition, please choose carefully.
4. If you don't know how to choose the type, you can also contact us to give you some suggestions.
Packaging list:
machine * 1, streamlined version of product manual * 1 (including warranty card), extension line * 1 (keyboard introduction, need to be purchased separately), product qualification certificate * 1
Supplementary Note:
A. If you need detailed version of product manual, you can contact us to send it to you free of charge.
B. If there is no paper product manual in the packing case, it is because of product changes or upgrades. Please contact us for the latest and accurate electronic product manual.
220V to 380V frequency converter is to solve the problem that the motor of electric equipment is 380V three-phase, but there is no 380V three-phase power supply around it, but only 220V single-phase power supply. The specific solution can refer to the following suggestions:
A. If the three-phase 380V motor itself is a star connection, it can be changed to a triangular connection. At this time, the motor becomes three-phase 220V motor, using our 220V converter to make single-phase 220V into three-phase 220V, the same level power selection can solve the problem (220v converter purchase can click on this link);
B. If the three-phase 380V motor itself is triangular connection, it can not be solved by changing its connection method. We must use our 220V to 380V converter to solve the problem, and pay attention to the selection.
C. Identification of motor connections can be referred to in the following figure:
Figure1 is a star connected motor.
Figure 2 is a triangular connection motor.
R, T are input terminals of frequency converter 220V power supply;
U, V and W are output terminals of frequency converter, connected with three-phase AC motor.
