Low Voltage Disconnect (LVD) Operations

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.
