Voltage sensitive relay wiring diagram. A typical 12v voltage sensitive relay vsr campervan wiring diagram. Hi i would definitely use a voltage sensitive relay system over an isolator in your application. 12 volt planet is an online supplier of low voltage electrical components and. When the voltage on the charged bank rises sufficiently the dvsr engages allowing the 2nd battery bank to charge. Wiring diagrams dvsr conections house b a t t positive s t a r t b a t t positive house batt positive tinned stud. In this video we explain the differences between voltage sensitive relay vsrs and battery to battery chargers.
Preventing cycling in battery combiners voltage sensitive relays and automatic charging relays 3 by wiring charge sources to the larger house bank the relay contacts need to pass just a few amps at best in order to charge the start battery. 125 amps continuous 140 amps intermittent ignition protected ul 1107 auto voltage sensing 12vdc or 24vdc max 32vdc. All of our systems are very easy to install if you follow the simple instructions. Battery isolators automatic charging relays also called acrs combiners or voltage sensitive relays are all intended to keep a load or loads from discharging the reserve battery system. 7 0 25a single sense vsr operation the voltage sensitive relay vsr allows two batteries to be charged at the same time. The reserve battery system is used for vital loads like engine starting navigation or communications.
Digital voltage sensing relay dvsr 1224v 710 140a the digital voltage sensing relay dvsr allows the charging of a second battery bank from any single charging source. Also saw a nice diagram of the wiring but you used both a vsr and an isolator. You will find all the components you need in the kit. This video shows what a voltage sensitive relay or vsr is and how to install one in a dual battery setup to make sure both batteries get charged but only one can go flat. Have a look at the diagram above to see the basic wiring diagram of your voltage. Have i oversimplified the issuedecision or perhaps ive missed something and its more complicated.
Instillation guide for a 12v voltage sense split charge relay system thank you for purchasing this kit from simply split charge. Now thanks to beps unique vsr voltage sensitive relay boat owners can enjoy the benefits of fully charged engine starting batteries and deep cycle house batteries with one easy to install charging system.
