Voltage Sensitive Relays
Voltage sensitive relays (VSRs) are electrical devices that monitor the voltage level in a circuit and automatically connect or disconnect the circuit based on the voltage level. They are commonly used in marine and automotive applications to manage the charging of batteries from multiple sources, such as alternators, solar panels, and shore power.
VSRs work by sensing the voltage level at a specific point in the circuit, typically at the battery terminals. If the voltage exceeds a predetermined threshold, the VSR will connect the circuit, allowing the battery to charge. If the voltage falls below the threshold, the VSR will disconnect the circuit, preventing the battery from discharging or overcharging.
VSRs are designed to be easy to install and operate, making them a popular choice for recreational boaters, RV enthusiasts, and off-grid homeowners. They offer a simple and effective way to manage multiple charging sources and protect batteries from damage due to overcharging or discharging.
RS offer a range of voltage sensitive relays from leading brands such as Schneider Electric, Phoenix Contact, Eaton, Omron, ABB as well as numerous others. We are sure you will find exactly what you are looking for.
