Why disturb perfection ?

 PWM (Pulse Width Modulated AC ) is an artificial chopped waveform

    Created by DC to AC conversion via the transistor inverter

    Heat related issues both in drive and other equipment

    Represent a variety of disturbance issues - including:

              Common mode noise, EMI - EMC, THD, URN and audible noise     

              Bearing currents and motor winding stress

              Hidden failures, also on other equipment on the same grid

PWM is a complex technology, challenging installation, higher failure rate, will never be noise free

 STADT LEAN PROPULSION® is based on perfect sinusoidal waveform

    No disturbance due to Dynamic Ultra Low Frequency Switching                       Technology

    No additional heat

    Lowest URN (Underwater Radiated Noise)

    Perfect source  for AC motors

Simplicity, eased installation, reliability, efficiency
