Maico 0157.1563 STX 4 speed controller

Speed controller for continuously variable control of fans. Minimum speed adjustable. Can be used for surface and flush mounting, exception: STX 4 only for surface mounting. Functional principle: phase control. Recommended distance from radio and television sets: 3 m. Switch on the fans to maximum speed by turning the control knob. Further turning reduces the speed. Splash-proof. Built-in temperature cut-off device. Orange LED operating display. CE mark. Including spare fuse. Additional switching contact (230 V), e.g. for controlling a flap. Due to the phase control technology, a physically caused humming noise can occur in the lower speed range. In rooms where low-noise fan operation is required, use 5-stage transformers TRE... to control the speed. Can be mounted on walls, avoid on ceilings due to temperature build-up.
