STRS-1 – transformer fan speed controller with TK, 230 V
The STRS1 transformer speed controllers are based on the principle of voltage control with auto-transformers. They are applicable to voltage-controllable motors (230 V, 50/60 Hz) to control in 5 steps the rotational speed (of fans, pumps, etc.). They are fitted out with (TK) contacts for thermal motor protection.
When choosing a controller it is important to know the maximum current intensity consumption on the taps. The indicated maximum current can be taken from each tap.
