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.

Transport Military Trailers with Commercial Trucks

Posted by Ernest Herz / May 05, 2015 / NEWS

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

Power Converters – Electric Facilitators in Specialty Vehicles

Posted by Ernest Herz / July 14, 2012 / NEWS

We live in a world of mobility and portability. A myriad of facilities, once existing only in stationary environments, operate today in mobile venues called specialty vehicles. They can be broken down by their three major user categories:
a) Civilian
b) Industrial
c) Military

Computers Trickle Down DC Power

Posted by Patel Ikshishni / June 17, 2012 / NEWS

All electronic devices require DC power to operate.

Many, who have assembled a modern PC are aware of the component diversity found within. Circuit topology identified by names such as TTL and CMOS, are implemented as parts of circuit function blocks such as CPUs, ROMs, RAMs, EEPROMs, and Hard Drives. Each circuit is known to have its particular voltage demands from the power supply. As well each of these circuit blocks may have its own DC-DC converter to make certain that not only does it receive proper voltage, but also to ensure that this voltage is maintained within close tolerances. Deviation from the nominal voltage may result in damage to the circuit or the loss of proper function causing data corruption. Typically these DC-DC converters are of the small step down mono blocks, which plug into a circuit board and supply a defined local circuit. Levels of power normally available from such DC-DC converters are in the 2 to 10 Watt range and their output voltages may have standard values specified by the manufacturers of the types of integrated circuits they are intended to energize. DC voltages of 3.3V, 5V, 12V, 15V, 24V are common.
