Single-phase two-speed fan speed controllers Rated current SEC: Rated voltage PRI: Control type: Autotransformer, single-phase, two-speed fan speed controllers equipped with a fuse. Switching between settings is done by shorting or opening CL-CL contacts, e.g. by an external clock. Regulators are equipped with two knobs, thanks to which the fan speed can be programmed, e.g. during the day and at night, and with two lights - green indicating power supply and red indicating motor thermal contact activation. Connecting thermocontacts protects the fan motor against overheating (the controller is switched off). ARWD/S/R version has a reset button for starting the regulator after the thermocontact has operated - controller does not switch on automatically. Made with Class II insulation and protection grade IP21 (ARWD 10 - 14) or IP54 (ARWD 1,5 - 7), max ambient temperature 40°C. Thermal class of insulation B (130°C).
