Motor Controllers

Based on 20 years of experience on EC drives technology for Fans and our R&D knowledge of ventilation and applications, we developed optimal combination of Domel EC motor and motor controller.

DFI - E3 include IP20 and IP66 controllers for HVAC and other industrial applications, and set a new cost competitive standard for dedicated fan and pump control. Ease-of-use and innovative design combined with robust performance provides powerful flow control and reliability in a compact drive. The HVAC controller E3, provides 98% drive efficiency combined with low input harmonic current distortion compliant with EN61000-3-12.
