Dimmer Control THE “ELECTRONIC” DIMMER CONTROL The Electronic Panel Lamp Dimmer Control is a cost effective, reliable method of safely controlling the intensity of dashboard lighting in the cab of heavy duty vehicles. Pollak Panel Lamp Dimmer controls have been specified by Mack Trucks, Freightliner, Peterbilt, and Kenworth. These manufacturers know that electronic reliability keeps trucks on the road and out of the shop. An electronic Panel Lamp Dimmer eliminates the old-fashioned rheostat type control. Sophisticated electronic pulse width control circuitry and power MOSFET technology used in the panel lamp dimmer’s design eliminates the heat build up found with traditional rheostats. Pollak’s two wire design allows the Pollak controls to be a drop-in replacement for existing rheostat applications. State-of-theart surface mount electronic design reduces the housing size and weight while eliminating expensive product failure caused by vehicle vibration. This Pollak Panel Lamp Dimmer is designed in accordance with stringent SAE J1455 recommendations. Load dump and transient conditions will not adversely affect the dimmer’s operation and it is completely protected from continuous short circuit overload. 10 amp maximum current load.
