PRODUCT DESCRIPTION
The STRS1 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-transformer(s), control the speed manually in five steps and
feature TK contacts for thermal motor protection. The used technology provides a
regulated output voltage with a perfect sinusoidal shape.
