QNK 5.5KW 7.5HP 220V AC 25A VFD Converter Single to 3 Phase Inverter Variable Frequency Drive for CNC Spindle Motor Speed Controller White

Excelente está funcionando bien

I used this VFD to control a 3-phase 5-hp air compressor motor. I used the slow start function to slowly start the motor over 5 second period. I used the compressor pressure switch to control the "run" feature. I let the compressor run for 30 minutes with open lines, then let it cycle several times. No problem with the motor or the controls. The only negative thing is the manual. You need reading glasses to be able to read it and it is poorly translated. More diagrams would be helpful. Other than the manual, it everything else was good.

Hard to install, no clear instructions . Does work as should once you figure out the installation .

vite et super facile a utiliser
