Dimmer (CB1592E)

Incandescent lamps, heaters and other resistive loads can be controlled by this circuit whose maximum current depends on the TRIAC used. The L1 coil that helps to filter the circuitry produced by the circuit consists of approximately 20 turns of common wire on a ferrite rod. The capacitor of 100 nF must have an insulation voltage of at least 100 V, and the value of the component in parentheses is for the case of the 220 V power grid. (Carga = Charge)
