Product details
Dimensions and technical data: Regulation of fan speed through the principle of phase-cut control (a humming noise may occur at lower speed ranges. Therefore, step transformers should be used in noise-sensitive areas). Setting the minimum speed via a potentiometer on the switch (the motor should start smoothly). When connecting multiple fans to a switch, a reserve load of 10% should be planned, and the rated load/maximum load must be observed. WS 1.5 and WS 2.5: suitable for standard flush-mounted boxes, compatible with switch systems from other manufacturers (requirement: rotary knob for 6 mm shaft). WS 5.0 and WS 10.0: switches for surface mounting, plastic (light gray/white).
