Low Voltage Disconnect (LVD) Operations
Low voltage disconnects (LVDs) are a type of voltage
disconnect device that are designed to protect batteries from damage due to excessive discharge and sensitive system loads from low battery voltage. Typically, discharging batteries beyond a critical low voltage can damage the batteries and/or load, and require a longer recharge interval. LVDs work by automatically
disconnecting the load from the battery when the battery voltage drops to a
certain predetermined level. Connecting LVDs (Negative Ground Model) LVDs are commonly used in battery-powered applications such
as solar power systems, off-grid homes, and RVs. These devices can help extend
the life of the battery by preventing over-discharge, which can damage the
battery and reduce its overall lifespan. They can also help ensure that
critical loads, such as emergency lighting or medical equipment, remain powered
even in the event of a power outage.
There are several types of LVDs available, including
electronic and mechanical LVDs. Electronic LVDs use microprocessors to monitor
the battery voltage and automatically disconnect the load when the voltage
drops below a certain threshold. Mechanical LVDs, on the other hand, use a
relay or switch to disconnect the load when the battery voltage drops.
Overall, LVDs are an important component in many
battery-powered applications, helping to protect equipment and extend battery
life. They are available in 12, 24 and 48V DC models as per your system needs. For your customized power solution contact an Rfwel Power Solutions specialist here.
