1. Feature
This power supply is a high-frequency inverter to drive the pump. The power supply controls
motor current to a fixed value and set the output voltage proportional to output frequency. Thus
the power supply gives full play to its ability and can start the pump in a short time.
The power supply shows the status of the pump and power supply on the display of the front
panel, for example, output frequency, operation status and so on.
! CAUTION
Table 1 shows the combinations of the power supply and the pumps. Check the model and
match the power supply with the correct pump.
