Economical solution for the dimming of aircraft interior lighting. These heavy-duty solid state dimmers by Superior Panel Technology includes all necessary potentiometers with built-in off switch and 115W power transistors mounted to a heat sink. The supplied colored Mil Spec wire and very easy to follow wiring diagram allows the aircraft builder to customize the wiring harness to fit individual needs. A solid state dimmer provides the most uniform dimming if you are dimming a combination of LEDs, incandescent bulbs and electroluminescent lamps on the same circuit (such as SPT’s Glow Strips, FiberLites, and LED glare shield light strip). They are rated for 2 amps per circuit, and the multi-circuit dimmers allow for two discrete power inputs (One for circuit one, and one for remaining circuits). Appropriate for both 14V and 28V systems.
