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,

choose a boost inverter that is 2 levels larger than the motor power.

4. The inverter cannot be connected to the braking unit and resistor,

and cannot be used in the occasions that require quick shutdown and

the occasions of potential load(such as cranes)

5. If you don't know how to choose the type, you can also contact us to give you some suggestions.

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.

OUR SUGGESTIONS

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.

(For motors that require fast shutdown and potential loads, inverters of the same voltage level are required and braking resistors are connected for normal use)

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.
