Low Voltage Disconnects

Low voltage disconnects (LVDs) are essential components in protecting batteries from excessive discharge and maintaining reliable power in critical vehicle and equipment systems. These automatic disconnect switches monitor battery voltage in real time and remove non-essential auxiliary loads when voltage drops below a set threshold—preserving battery capacity for vital functions like engine starting. 

Used in commercial vehicles, emergency fleets, off-road equipment, and marine applications, LVDs extend battery life, reduce maintenance needs, and help prevent unexpected downtime due to dead batteries. Waytek’s lineup includes trusted brands like Blue Sea Systems, Sure Power, and Cole Hersee by Littelfuse, offering a variety of current ratings, form factors, and programmable set points to suit your application. 

By eliminating the need for separate timers or voltage-sensing relays, these low voltage disconnect modules simplify system design and wiring—delivering plug-and-play power protection.
