VOLTAGE SENSING/SENSITIVE SPLIT CHARGE RELAY VSR 12V 140A CAMPERS CARAVANS BOATS
Description
Description

OUHOUG® Digital Voltmeter Display Voltage 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 (assuming 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 will gradually 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 Vans, Motor homes, 4x4s, Day Vans, Mobile workshops,Cars or Boats. 
For 12V Leisure Battery Capacity up to 220AH

Highlights compare to old version VSR without Digital Voltmeter Display:
  • Digital Voltmeter Display for sensing battery voltage
  • Emergency Switch button for auto or manual charging mode
  • Hardware inside VSR fully upgraded with more reliable and higher quality components
Features
  • Designed for dual battery systems
  • Automatic operation
  • Simple to install (no need to modify factory-fitted electrical system - no warranty issues)
  • 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 being charged by a mains battery charger by solar power or other charging source.
  • Emergency engine start feature to combine the batteries
  • Automatically sensing voltage level of main battery
  • Emergency Charge Function
  • IP65 Waterproof
  • Easy to install
