Low Voltage Disconnects

Low voltage disconnect switches are designed to protect batteries from excessive draw. Think of them as similar to circuit protection devices, but instead of terminating connection when voltage spikes, they disconnect when voltage drops too low, preventing damage to the batteries and load. To do this, a semiconductor switching circuit measures battery voltage; when it dips too low, predetermined auxiliary loads are switched off to ensure the battery has enough power left for engine starting.

This prolongs battery life by preventing damage due to excessive discharge and eliminates the need for separate timer or voltage sensing devices which simplifies wiring and installation and allows for a streamlined design.
