Low Voltage Disconnect Switches & More

Low voltage disconnect switches are solid state electronic modules 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.

These low voltage disconnect switches automatically disconnect and reconnect loads based on battery voltage, no operator action required. This prolongs battery life by preventing damage due to excessive discharge and eliminates the need for separate timer or voltage sensing delay relay devices, and high current relays or solenoids, which simplifies wiring and installation and allows for a streamlined design.
