STEP's air cooled VFD was particularly developed for HVAC industry. It adopts mature control technology, the ratio between voltage/frequency is automatically adjusted according to the motor load, thus greatly improving the efficiency of the system. A good heat dissipation is kept by using air cooling method, efficiently lowering energy consumption.
