Part 2: Centralized Power Switching Regulators (DC-DC Converters)

As we mentioned in Part 1 of this series, North American commercial vehicles’ electrical systems are different from those used in Europe and by the NATO military. Variations in voltages and connectors require the use of electrical trailer interfaces. Part 1 focused on power resistor voltage dividers. In this section we’ll go over another electrical trailer interface — centralized power switching regulators, otherwise known as centralized DC-DC converters — including this interface’s advantages and disadvantages.

1224-7Tow NATO military trailers with commercial transport trucks and avoid contravening State and Federal highway regulations. ETC 1224-7 enables the activation of NATO trailer electrical functions normally as they are moved with standard USA transport tractors. Quick and effortless installation with no hard wiring makes ETC 1224-7 easily transferable from one vehicle to another. This electrical conversion box is lightweight and compact at only 15 pounds. This makes practical the mounting of the trailer electrical interface to either truck or trailer depending on where it is needed most. No hard wiring or cumbersome installation is involved.

1224BPart 1: Interfacing Methods For Vehicles with Incompatible Electrical Standards

North American commercial vehicles have electrical systems unlike those of Europe and the NATO military. Specifically, they operate at different voltages and use dissimilar connectors. As examples of wiring conventions, North American commercial vehicles use a 7 Pin SAE 560 system and NATO vehicles use a 12 pin system conforming to the STANAG 4007 standard. The European configuration is similar to the North American 12 V based SAE 560 system except that they are 24V based and use either a single ISO 1185 connector or one in combination an
