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 12-30, LVD 12-75 (Neg. Ground) LVD 24-20, LVD 24-50 (Neg. Ground) LVD 48-30 (Pos. Ground) For high current model, see PFM-400 |

Typical LVD Installation
Application notes:
• 1 sec. switch over delay may not be suitable for data transceivers. Instead, use 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 but will not restore a deeply discharged battery.
A separate high current charging source is required.
