Low voltage disconnect

The LVD protects the batteries. The LVD disconnects the load from the batteries when a preset low voltage, which can cause permanent battery damage, is reached.

The LVD is available in brown or grey (faceplate only). The nominal dimensions are 6.60 inches high, 10.25 inches deep, and 2.2 inches or 5.85 inches wide. The LVD is designed to be housed in the power shelf and is used primarily in embedded applications.

The Low Voltage and Low Voltage Disconnect alarms are visually displayed on the LVD unit and can also be monitored externally.
