Low Voltage Disconnect Switches and More

Low voltage disconnects (LVDs) are solid state electronic modules designed to protect batteries from excessive draw. Think of them as similar to circuit protection, but instead of terminating the connection when voltage spikes, they terminate when voltage drops too low. Discharging batteries beyond a critical low voltage can damage the batteries and load, and requires a longer recharge interval. A low voltage disconnect prevents this from taking place. A semiconductor switching circuit measures battery voltage, and when battery voltage drops too low, predetermined auxiliary loads are switched off to make sure that the battery has enough power left for engine starting. Our low voltage disconnects electronically sense battery voltage and conserve starting power. These LVD’s automatically disconnect and reconnect loads based on battery condition; no operator action is required to protect the batteries. This prolongs battery life by preventing damage due to excessive discharge and eliminates the need for either separate timer or voltage sensing delay relay devices and high current relay or solenoid, and simplifies wiring and installation. Their small size and lightweight design makes it easier to install, uses space more efficiently, and eliminates hardware.
