Speed controllers for single-phase motors

General

Variable control of fan speed

For fans with 1x230V voltage supply via voltage control

With the EFC speed controller it is possible to provide variable control of the motors' rotary speed and thus to vary fan capacity from 25-100%. The controllers have integral on-off knobs and internal minimum trimmer, allowing the minimum voltage/airflow to be set.
