The SC2-1 series of transformer fan speed controllers regulate the rotational speed of single-phase voltage controllable motors by varying the output voltage. They are equipped with auto-transformers and control the speed manually in five steps. The SC2-1 also feature contacts for remote start / stop. The controller makes it possible to select two optimal motor speeds and to switch these by a contact (e.g. day / night control). In this way energy savings can be realised. The controllers up to 7,5 A are available in a plastic enclosure, while the models above 7,5 A are available in a metal enclosure.
