Its low on-resistance (\u0026lt;0.003 ohm), dual-color LED indicators, and selectable AUTO\/ON\/OFF rocker make it suitable for solar setups, alarm systems, UPSs, and mobile applications where preserving battery life and preventing total discharge are priorities.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the LVD module keep a battery from deep discharge?\u003c\/h3\u003e\n\u003cp\u003eWhen set to AUTO, the module measures battery voltage and disconnects the load if the voltage stays below the programmed cutoff for 5 seconds, avoiding nuisance trips from transient dips.
