Cole Hersee Co offers various battery isolators for the trucking industry. The unit's solid-state switches are ideal for trucks using a standard battery to start the vehicle and a second battery to run auxiliary appliances in the cab or sleeper. These isolators direct charging current into the battery with the lower charge, allowing the starting battery to provide a strong burst of energy to start the engine, while running the equipment off the second battery.
These isolators are electronic sealed units that contain two diodes. Power supplied to the middle stud of the isolators flows to each of the other studs. As current can flow in only one direction, current cannot drain from one battery to the other, so each stays properly charged. The units are solid-state, protected against contaminants, and can withstand vibration and temperature extremes. They come in a range from 42 to 250 amps, for systems of 12 to 36 volts DC.
