Avtech’s 1826 series DC-DC Lamp Dimmer is a 75 Watt, Pulse Width Modulated DC-DC power supply which provides variable, 0 to 5 VDC, 15A maximum power to the flight deck based upon the setting of a 10K ohm potentiometer situated on the flight instrument panel.

Housed in an aluminum enclosure, the 1826 series can be easily mounted to the aircraft with two pan-head screws through open-end slots cut into the base plate flanges on opposite sides of the unit.  Electrical connections are made through a single connector.
