ProMariner ProNauticP 1240P 40 Amp 3 Bank Battery Charger

The ProMariner ProNauticP 1240P is a 40A three-bank charger for 12V marine systems, running on the all-digital ProMar platform.

Forty amps is the high-output model in the ProNautic 12V range, sized for boats with substantial DC loads that need banks brought back quickly rather than trickled overnight. Distributed-On-Demand is what makes that output count. Current goes to whichever bank needs it instead of holding a fixed share in reserve for a battery that is already full.

Selectable profiles cover flooded, AGM and gel batteries, and automatic conditioning, maintenance and periodic reconditioning keep supported banks ready between trips. Power-factor-corrected auto-ranging 100-250V AC input lets the charger work across the range of shore supplies encountered in different regions.

Dual digital displays show real charging voltage and amperage rather than an indicator light, and separate fault indication points at wiring or bank problems interfering with charging. Automatic temperature compensation and fan-speed control adjust operation as ambient and battery conditions change. Explore more 3-bank battery chargers.
