The A & T Labs panel light dimmer provides features and functionality not available in other commercial dimmer products.
Features
3 outputs with a tracking capability - One output is the “Master”, and the other two can be set to track the master from 0 to any set voltag behind the master. This allows items on the dimmer bus to be grouped according to their relative brightness for better overall tracking. For example, the Vision Micro- systems products are typically way out of line in brightness compared to others at the same voltage
Quiet analog design
Multi-channel tracking capability
Daylight full-on over-ride capability for GPS annunciators, etc.
Current limiting/short circuit protection
Thermal protection
Low drop-out voltage (ability to adjust the dimmer bus up as close to the battery voltage as possible)
Photocell light sensor automatic control capability
Low cost
Voltage range: 0 to Input supply - .6V
Output current -Depends on ventilation - Each channel is capable of 5 amps, practical dissipation limitation is ~ 5 amps total for all channels. (For 28 volt systems, current limit is 1 A per channel) Unit connections are made through a DB15 connector, and are easy to integrate into the rest of the aircraft wiring.
