Speed controller STX 2.5 – M0157.1562

Speed controllers for stepless regulation of fans. Minimum speed adjustable. Can be used for surface and flush mounting, exception: STX 4 only for surface mounting. Operating principle: Phase-angle control. Recommended distance to radio and television sets: 3 m. Switching on the fans to maximum speed by turning the control knob. Further turning reduces the speed. Splash-proof. Integrated thermal cut-out. Orange LED operating indicator. CE mark. Includes spare fuse. Additional switching contact (230 V) e.g. for controlling a flap. Due to the phase-angle control technology, a physically induced humming noise may occur in the lower speed range. In rooms with a demand for low-noise fan operation, use 5-step transformers TRE.. for speed control. Mounting on walls is possible, avoid on ceilings due to temperature development.
