Speed controller for continuous control of fans. Minimum speed adjustable. Can be used for surface and flush mounting, exception: STX 4 only for surface mounting. Functional principle: Phase angle control. Recommended distance to radio and television: 3 m. Turn the control knob to turn the fans on to the maximum speed. Further turning reduces the speed. Splash-proof. Built-in temperature cut-off fuse. Orange LED power indicator. CE Label Including spare fuse. Additional switching contact (230 V), e.g. for controlling a flap. Due to the technology of the phase angle, a physically conditioned humming noise can occur in the lower speed range. Therefore, use 5-stage transformers TRE... for speed control in rooms with the requirement for low-noise fan operation. Can be mounted on walls, avoid on ceilings due to temperature development.
