The undervoltage protection m-LVD (Low Voltage Disconnect) from Blue Sea Systems continuously monitors the battery voltage and automatically disconnects less important consumers as soon as an adjustable undervoltage threshold is reached. This leaves enough residual capacity in the battery to safely start the engine.
Advantages
- Status light warns of low battery voltage before shutdown
- Optional alarm output for an additional acoustic warning signal before disconnection
- Remote control switch allows adjustment of the disconnect voltage, a 10-minute shutdown delay, temporary disconnection until the voltage rises again, and alarm muting
- One-piece stainless steel flange nuts for secure and corrosion-resistant connections
- Recesses for labeling tags for easy circuit identification
- Included in delivery: Remote control switch (Contura) 7928
Technical Data & Compatibility
- Rated voltage 12 V DC
- Disconnect voltage adjustable from 11.3 V to 12.1 V, re-engage voltage 13.0 V DC
- Continuous current 65 A, intermittent current 115 A (5 minutes)
- Cable cross-section 6 AWG (16 mm²); connection bolts 1/4"-20 (M6)
- Ignition protected according to ISO 8846 and SAE J1171
What is undervoltage protection like the m-LVD used for?
Whenever non-safety-critical consumers – such as cool boxes, lighting, or entertainment electronics – need to be automatically switched off when the battery voltage drops, so that the starter battery always retains sufficient capacity for starting the engine. The m-LVD thus reliably protects against deep discharge without the need to constantly monitor the voltage display.
