Marinco Battery Distribution Cluster for Single Engine. A two-position switch combined with a Digital Voltage Sensing Relay (DVSR) to make sure your boat always has a fully-charged battery.The Digital Voltage Sensing Relay (DVSR) provides an efficient and inexpensive solution for automatic charging of a second battery bank. It ensures correct charging without the risk of a dead starting battery.When the voltage of the first battery bank rises sufficiently, the DVSR engages, allowing the second bank to charge. When charging stops and voltage falls, the DVSR automatically isolates the battery banks, ensuring that the engine starting battery is fully charged.Digital circuitry provides superior reliability and very low power consumption. The 714-140A-DVSR uses a dual sensing DVSR (710-140A). This system ensures you will always have a fully charged reserve battery.When the switch is in position one, battery bank one becomes the sensing battery for the VSR. Battery bank two, which is in isolation, will be charged via the DVSR when the engine is running, ensuring it is always fully charged. When the switch is in battery two position, this becomes the sensing battery and battery one is charged via the VSR.The fact that there is always a fully charged battery in reserve is a huge safety factor. Please note: With the 714-140A-DVSR the electronic loads are run off the same battery as the engine starting battery.Key FeaturesSafely charge two or more independent battery banks from one charging source (alternator, battery charger)Charges engine starting bank first, before combining auxiliary bank for chargingProtects your starting battery from being discharged by house bank loads Isolates electronics from harmful voltage surges caused by the starter motorSimple-to-install three-wire connection leaves alternator wiring intactNo voltage drop as with diode isolatorsSurface or panel mounting
