UTC 2412-7B Electrical Interface
Military/European Tractor - USA Trailer
UTC 2412-7B is a direct electrical interface to be connected between a 24 Volt military tractor or a European Commercial Tractor and a 12
Volt American Commercial Trailer. It is equipped with two input receptacles which offer the towing vehicle's operator the following options:
a) If the tractor is military (24 Volt NATO Connection) the operator connects via J1 (Figure 1).
b) If the towing vehicle is a European commercial type the operate connects to J2 (Figure 1).
Total Conversion
UTC 2412-7B electrical interface incorporates 6 independent circuits that supply a total of up to 800 Watts of 12 Volt power for all trailer electrical demands.
Quick Installation
UTC 2412-7B electrical interface can be installed swiftly because it is designed to accept standard connectors and requires no hard wiring.
Reliable
UTC 2412-7B incorporates highly efficient circuitry. This translates into cool operation, high reliability, and long life expectancy. UTC 2412-7B 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 2412-7B is compact, weighing only 19 pounds. It has a low physical profile and can easily be mounted on tractor or trailer bodies.
