SC Speed controller

SC speed controllers utilise triac phase cutting techniques and should be used with motors which have been approved by the manufacturers for speed control by this method. Control is best achieved with propeller, axial or centrifugal fan loads where absorbed power at full load corresponds to at least 90% of the motor's capacity.The SC 3 is housed in a plastic enclosure rated to IP40 and designed for continuous operation with a maximum of 3.0 amp loads at 40°C ambient on single phase 220/240V 50Hz supply.
