AI² Light Dimmers are available at power levels from 38 watts, single channel, to 375 watts, five channels. Dimmers are supplied as standard OEM equipment to provide user adjustable light intensity variations in the cockpit or other interior areas of an aircraft. Light weight, small size and highly reliable light dimmer units are achieved from an advanced high frequency resonant fly forward converter topology.

Light dimmers are designed and qualified to operate in the most stringent environments. Light dimmer units are qualified to meet FAA and military standards for mission critical equipment. Applications range from large-scale commercial air transport, to corporate and private aircraft, as well as military and commercial helicopters.

Single and multiple channel light dimmer units are available with remotely adjustable outputs at 0-5VDC, 0-12VDC and 0-28VDC. Light dimmers are available as either rheostat, potentiometer or voltage controlled units, as well as fixed output for powering DC based equipment. With the use of fast response current controlled circuitry, matching brightness criteria can be provided. Resonant high frequency switching achieves a light dimmer design topology that can meet customer specifications for light intensity control requirements.
