»Fleet must remain aware of the impending voltage changes on the horizon and the subsequent changes to maintenance practices. 134716874 | Vitpho | Dreamstime.com LED driver with voltage regulator ed and adopted as the industry pushes toward efficiency and attempts to obtain the ever-increasing and ever-present demand for more power. Built on 12V North American commercial vehicles on the road today, for the most part, are utilizing a 12V electrical system. "For our current production vehicles, the electrical system is primarily supplied with electrical energy via 12V direct current (DC) lead-acid batteries, with two or more connected batteries dependent on the energy requirements for the vehicle configuration," says Ash Makki, product marketing manager, Volvo Trucks North America, a global truck and engine manufacturer. The electrical system contains a series of batteries to provide electrical power throughout the vehicle. The number of batteries in a series varies from vehicle-to-vehicle; vehicles equipped with electrical power units (EPUs) may have a series of up to eight batteries. EPUs are present on SMD LED »Optronics has designed a voltage regulator inside each light in order to regulate incoming voltage to the proper level.
