m-LVD Low Voltage Disconnect
7635
Features
Senses low battery voltage and automatically disconnects
devices to save power for starting or to preserve battery life
A dead battery is one of the most common reasons for a tow. Don't get stranded with a dead battery. The m-LVD senses low battery voltage and automatically disconnects non-essential devices to save power for starting or to preserve battery life. The m-LVD is ideal for any single battery boat or vehicle that wants to avoid getting stranded with a dead battery.

- Status light in both m-LVD and Remote Control Switch provides visual warning of low voltage state prior to disconnect
- Alarm output available for audible warning of low voltage state prior to disconnect (optional alarm required)
- Remote Control Switch Functions:
- Disconnect Voltage Adjustment - Sets desired disconnect voltage
- Override - Temporarily delays circuit disconnect for 10 minutes
- OFF - Temporarily disconnects circuits until voltage rises
- Override or OFF - Silences alarm (optional alarm required)
- Case design allows surface, front panel, or rear panel mounting
- Rear insulating cover protects rear contacts
- Waterproof – rated IP67 for temporary immersion

Frequently Asked Questions
Q: Will the unit restore power automatically if the voltage level rises back up above cut-off?
A: The m-LVD will will reconnect when voltage is above 13.0V for 2 minutes or 13.5V for 30 seconds.
Q: Can the m-LVD be used to charge an auxiliary battery?
A: No, an ACR would be the correct device for charging applications.
Q: Will the m-LVD unit work with a 24V system?
A: The m-LVD was designed for 12V DC systems only.
Q: Why didn’t my 7635 disconnect after 5 minutes?
A: The battery voltage must stay below the disconnect threshold for 5 minutes before the unit alarms. It will then take another 5 minutes of alarming before the unit disconnects, unless the remote control switch is used to manually disconnect. This means it may be a total of 10 minutes from the moment battery voltage drops below the threshold before the unit disconnects.
