Updated Dial Display Voltage Sensitive Split Charge Relay VSR 12V 140A For Camper Car RV Yacht Steamer Smart Battery Isolator

DescriptionOUHOUG®Dial DisplayVoltage sensitive relays, or VSRs, sense the voltage of the starter battery and close the contacts inside the relay at a pre-set threshold 13.3V . The contacts then open again at a pre-set lower threshold 12.8V. So when the alternator starts turning the voltage rises to around 13.3V or higher at the starter battery terminals (auming the battery is already well charged) and the relay will close to allow current through to charge the leisure battery. When the engine shuts off and the alternator stops turning, the voltage wilradually drop away at the starter battery terminals and the relay will open again when the voltage is lower than 12.8V, isolating the batteries once more.Applications:For Camper , Motor homes, 4x4s, Day , Mobile workshops,Cars or Boats.For 12V Leisure BatteryCapacity up to 220AHHighlights compare to old version VSR without Dial Display:Dial Display for sensing battery voltage Switch on for auto or manual charging modeHardware inside VSR fully upgraded with more reliable and higher quality componentsFeaturesDesigned for dual battery systAutomatic operationSimple to install (no need to modify factory-fitted electrical system - no warranty iues)Generally dual sensing, meaning that they operate when sensing a voltage rise on either side of the relay. This means that the starter battery will also charge when the leisure battery is g charged by a mains battery charger by solar power or other charging source. engine start feature to combine the batteriesAutomatically sensing voltage level of main battery Charge FunctionIP65 WaterproofEasy to installSpecificationVoltage/Current: 12V/140AmpCut In Voltage: 13.3VCut Out Voltage: 12.8VIA6949-2016 CertifiedCE CertifiedPackage Includes:1x VSR with fitting hardwares1x ManualPacking list
