Frequency Inverters 3.7 kW (4 kW)

How to switch frequency inverters to 4 kW?

Vector frequency inverters 3.7 kW can potentially be used for higher power as a frequency inverter 4 kW. This can be achieved if switched to scalar control and "Pump" mode in the menu, which is characteristic for pumps and fans without inertial load. This may allow you to purchase a frequency inverter 4 kw cheaper than a model with "reserve" for 5.5 kW.

Pay special attention to the nominal current and overload resistance, which such an inverter at 4 kW will have in V/f mode. The power part will burn out if the increased current during motor start-up exceeds the allowable values.

So, although this is a cheaper option for managing electric motors 400 W, the next model in the standard range is better suited—with a power circuit at 5.5 kW.

You can pick up the inverter by self-collection from Kam'yanske in the Dnipropetrovsk region or order it for delivery by Nova Poshta to Kyiv, Bila Tserkva, Lviv, Rivne, Dnipro, Kharkiv, Odesa, and other Ukrainian cities. Delivery payment according to the carrier's rates.
