Phillips Industries introduced the Permalogic Selector System, an intelligent controller that chooses the optimal source of power to fully charge liftgate batteries without draining power needed for other equipment functions.


For reefer fleets, the system automatically selects between the tractor (via dual pole) or the trailer's reefer unit as the source of power to continuously charge the liftgate batteries to capacity. The tractor is the primary source of charge, but if the tractor voltage drops to 12.2V, the system will shut off this source of power to eliminate any low voltage starting issues. It then utilizes the reefer for the power source if the reefer is operating correctly and producing more than 13.2V. The system will automatically shut off if it senses a problem with the reefer's electrical system and will not cause any out of balance issues with either the reefer unit or the tractor.

Bruce Purkey, president of Purkey's Electrical Consultants, who helped develop the product with Phillips, explained, "In today's environment where fleets are looking for ways to reduce idle times, engine shutoffs can negatively affect the ability to keep the liftgate batteries charged for trailers with high duty cycle liftgates. Delays cause inefficiencies, higher operating costs and poor customer satisfaction. Phillips wanted to develop a product that could automatically select the best source to recharge the liftgate battery and, at the same time, manage power to start the engine, run the refrigeration unit and maintain the integrity of the electrical system."
