ETC 1224-7 Electrical Interface
NATO Trailer Converter
ETC 1224-7 is a direct electrical interface to be connected between a 12 Volt commercial tractor and a 24
Volt NATO (military) Trailer. The ETC1224-7 accepts 12 Volt inputs from a standard commercial JAE560 pigtail connector. It converts these inputs to the appropriate 24 Volt levels that it makes available to the trailer via an MS75021-2 connector (as would appear on a military tractor).
Total Conversion
ETC 1224-7 electrical interface incorporates 6 independent circuits that supply a total of up to 800 Watts of 24 Volt power for all military trailer electrical demands.
Quick Installation
ETC 1224-7 electrical interface can be installed swiftly because it is designed to accept standard connectors and requires no hard wiring.
Reliable
ETC 1224-
7 incorporates highly efficient circuitry. This translates into cool operation, high reliability, and long life expectancy. ETC 1224-7 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
ETC 1224-7 is compact, weighing only 17 pounds. It has a low physical profile and can easily be mounted on tractor or trailer bodies.
