BLUE SEA AUTOMATIC CHARGING RELAYS

M-LVD LOW VOLTAGE DISCONNECT

Optional Features • Remote LED indicates status - requires optional LED or Remote Control Contura Switch with Integrated LED (included in retail package). • External alarm output to provide a low voltage warning prior to disconnect - requires alarm.

Senses low battery voltage and disconnects non-critical loads to save

power for engine starting. • 65 Amp continuous rating • 12V DC voltage input • Faster disconnect at lower battery voltages. • A single press at the remote control switch will delay disconnect. • Load can be manually disconnected using remote control switch. • LED flashing frequency increases as m-LVD approaches disconnect. • Case design allows surface, rear, or front panel mounting options. • Snap-on cover insulates terminal connections. Automatically combines batteries during charging, isolates batteries when discharging and when starting engines. • 65 Amp continuous rating. • 12V/24V DC auto ranging voltage input. • Senses charging on two battery banks. • Case design allows surface, rear, or front panel mounting options. • Snap-on cover insulates terminal connections. • 7/16" (11 mm) stud length • Integrated LED indicates ACR states. • 1/4" × .032" male quick connect terminals for ground and start isolation connections. M-ACR AUTOMATIC CHARGING RELAY WITH OPTIONAL START ISOLATION 8-27635 PART NO. • Integrated LED or optional remote LED indicates status. • 1/4" × .032" male quick connect terminals for ground & control connections.
