Split Charge Relay Circuit

The split charge relay switch will on and allow currant to flow through to the leisure battery when the voltage rises above 13 2volts.

Split charge relay circuit.

A 12 volt relay often called a manual split charge relay is an electronic device that uses an electromagnet to pull a set of contacts that make or break a circuit. This system uses a heavy duty version of a simple make and break relay the coil of which is energised by a signal that is only 12v when the engine is running usually the charge signal wire from the alternator.

The diodes or fet s on the single circuit of a multi output charger are only there to prevent parallel back drain when the charger is turned off. Voltage sensitive charging relays. How does a 12 volt relay work. An acr achieves the same exact outcome preventing back drain by opening the relay when no charging is present.

Will an acr manage the charge of my individual battery banks. A 12 volt relay is the same type of relay that you would find in many 12 volt electrical systems. When the engine is not running ignition is off the split charge relay will open and disconnect the batteries. With a multi metre you can check that the voltage on both batteries are the same to ensure everything is.

Acrs use a relay combined with a circuit that senses when a charging source is being applied to either battery. Typically split charge relay is controlled by the ignition wire so that when the engine is running ignition is on the split charge relay will close and connect both main battery and auxiliary battery.
