Using a MASTER dimmer combined with a SLAVE dimmer allows to increase the total load power to be adjusted. The combined use of the two devices is only possible if the load is electrically divisible in order to respect the maximum permissible power on the respective devices.

Inductive loads refer to electromechanical and electronic dimming transformers used to power 12V or 24V lamps.

Resistive loads refer to 230V (mains voltage) incandescent or halogen lamps.
