Specifications

The Electronic Panel Lamp Dimmer Control is a cost
effective reliable method of safely controlling the intensity of
dash board lighting in the cab of 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 fashion 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 rheo-stat applications, (see chart for
appropriate part number). State of the art 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,
As dash panels become more complicated the strain on the
panel dimmer is increased. The truck O.E.M.'s know this and
have converted to electronic dimmers.
If you can't afford the down time to have your lights go out contact your nearest Pollak
®
distributor today.
NOTE: If Panel Lamp Dimmer is hooked up backward, the unit will not work. This will not damage the
unit but it is important to insert terminals correctly
