UTC 2412-8
NATO Tractor to USA Trailer Converter
UTC 2412-8 is a direct electrical interface between a 24 Volt military tractor and a USA commercial trailer. The UTC 2412-8 accepts 24 Volt inputs from a NATO 12 pin connector. It converts these inputs to the appropriate 12 Volt levels that it makes available to the trailer via a standard SAE 560 connector (as would appear on a commercial tractor).
Total Conversion
UTC 2412-8 electrical interface incorporates 6 independent circuits that supply a total of up to 800 watts of 12 Volt power for all USA commercial trailer demands.
Quick Installation
UTC 2412-8 electrical interface can be installed swiftly because it is designed to accept standard connectors and requires no hard wiring.
Reliable
UTC 2412-8 incorporates highly efficient circuitry. This translates into cool operation, high reliability, and long life expectancy. UTC 2412-8 is designed to operate over a wide temperature range and under rigorous vibration and shock conditions. Its ruggedness is enhanced by weather proofing and electronic protection against abnormal conditions and output overloads.
Compact
UTC 2412-8 is compact, weighing only 17 pounds. It has a low physical profile and can easily be mounted on tractor or trailer bodies.
