In the network communication systems where DC loads are voltage sensitive attempting to operate from a low voltage input could damage the powered equipment and permanently reduce the battery capacity, thus installing a low voltage disconnect (LVD) in the circuit is advisable.
LVDs offer three essential functions: Protects sensitive powered equipment from damage caused by low input voltage; Battery recharge interval is much shorter because battery is disconnected before it runs totally flat; and Batteries are protected from early death often caused by excessive an unnecessary discharge. Units are available in rack and wall mount configurations.
Features

• Use with positive, negative or floating ground
• Status lights indicate system and battery connect/disconnect status, assisting technicians in system
troubleshooting
• Summary alarm contacts (form C) allow remote indication of system status
• Separate high amp ground bus provided
