This module means that you can control ohmic & inductive loads e.g. motors heating elements filament lamps etc.. It is not suitable for fluorescent lamps or motors with a starting capacitor e.g. washing machine motors. To control the output a 470kandohm linear potentiometer Order Code JM75S is required. For fine control a 100kandohm linear potentiometer Order Code JM74R may be added. This module has a load capacity without additional cooling of a maximum of 800VA. If a heat sink ribbed cooler minimum dimension approx. 10 x 6 x 2 cm or any similar cooling metal surface is used loads up to 2600VA may be connected.
