Low Voltage Disconnect | |
| Low Voltage Disconnect-LVD Discharging batteries beyond a critical low voltage can damage the batteries and/or load, and require a longer recharge interval. A low voltage disconnect prevents this condition. The LVD contains a sense and control circuit housed in a compact, rugged, vinyl-clad aluminum case. It is installed in-line between the battery and the load. The unit continually monitors battery voltage and if it falls below a preset voltage threshold, the load is automatically disconnected. When batteries are recharged past another pre-set voltage the load is reconnected. Connect and disconnect points are user adjustable. Models: LVD 12-75 (Neg. Ground) LVD 12-30 (Neg. Ground) LVD 24-50 (Neg. Ground) LVD 48-30 (Pos. Ground) |

Typical LVD Installation

Application notes:
• 1 sec. switch over delay may not be suitable for data transceivers, use instead a system where
the battery is floated on output of power supply see Power Pac or IPS or APS.
• Trickle charge current will maintain a back up battery and will slowly restore a deeply discharged
battery. A separate high current charging source is recom- mended for deep discharge recovery.
