It also prevents the starting battery from being run down by your equipment when the engine is off. BATTEK Voltage Sensitive Relay 12V 140A Dual Sense (Smart Battery Isolator) 52. Battery isolator (or split charge relay) allows an auxiliary battery to be charged by the vehicle’s system, yet not participate in engine starting. Ideal for charging a secondary battery bank from a battery charger with only one output such as: a combined inverter/charger (ProCombi). The BOM on Jeremy S Cooks build is extremely short just a PIR sensor and an optoisolator, with a battery, a plug for the cameras remote jack. 12V, 140A rated voltage sensitive relay (VSR) from Durite for split charging applications in camper vans, motorhomes, 4x4s and boats. Inexpensive 12 volt Smart Battery Isolator with 150+ amps pass-through and solid-state control. Auto 12/24v selection, if it senses 4v to 16V = 12V & 16v to 30V = 24V Bi-directional charging, this functional allows the charging from primary to auxiliary and vice versa allowing the maintenance of potentially 13.3v on all banks. Switches - Gray Engine disconnected Output relay connect 00 New Open TBG and. Timer for interior Lighting, which prevents the internal lights inside a vehicle from being left on and draining the battery the 48540 Smart Battery Isolator Controller.

New search features Acronym Blog Free tools. The VSR therefore ‘saves the day’, when the engine is ‘off’ and you attempt to run a 2000W appliance (bow thruster/anchor winch) from a depleted auxiliary battery bank the relay will latch and prevent you withdrawing circa 200A of current from the primary (engine starter battery), thus engine starting is always possible. Start Load Disconnect Isolator for Manager 30 Battery Management System. VSR is defined as Voltage Sensing Relay rarely. The top relay will be activated and battery +12 volts power will be supplied to the. When the voltage of the primary drops down to 12.9v the relay disengages and prompts the charging of the primary battery, hence ‘voltage sensitive’. 15 volts is the max voltage for the Lingenfelter twin pump set up. When the primary battery exceeds 13.3v the VSR assumes that the charging device (engine/alternator) is active and engages relay to connect mains to the auxiliary battery bank(s) to charge. Totaly automatic operation - does not require ignition feed. 12 Volt or 24 Volt automatic voltage selection.
