UTC 2412-7H
NATO Tractor to USA Trailer Converter
UTC 2412-7H is a direct electrical interface between a 24 Volt military tractor and a USA commercial trailer. The UTC 2412-7H 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) or via hard wiring to the trailer. In the case of hard wiring to the trailer the output receptacle can be used as an input receptacle when the user wishes to have the option of plugging into the UTC for all cases.
Total Conversion
UTC 2412-7H 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 2412-7H electrical interface can be installed swiftly because it is designed to accept standard connectors and requires no hard wiring. The UTC 2412-7H is designed to be mounted horizontally, which makes it ideal for flatbed trailer use.
Reliable
UTC 2412-7H incorporates highly efficient circuitry. This translates into cool operation, high reliability, and long life expectancy. UTC 2412-7H 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 2412-7H is compact, weighing only 17 pounds. It has a low physical profile and can easily be mounted on tractor or trailer bodies.
