Company Description: We are producing frequency inverters called NFO SINUS to control the speed of AC motors.It is a new technology based on two registred patent enables to supply AC motor with pure sinusoidal output waves.This method is new one and more progressive to compare it with usual PWM inverters.All negative influances of PWM are excluded-Gives pure sine-wave motor current and voltage.No EMC interference .No filters needed.No inductances needed.No derating of AC motor which means economical longlife running |
