Controller 5-step fan speed TK monitoring STRS-1-75L22

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 monitoring for thermal motor protection. The used technology provides a regulated output voltage with a perfect sinusoidal shape. The controllers up to 7,5 A are available in plastic enclosure, while the models above 7,5 A are available in a metal enclosure.
