ProMariner ProNautic 1220P 20 Amp 3 Bank Battery Charger

The ProNauticP Digital Performance Charger by ProMar is the ultimate solution for marine enthusiasts seeking reliable and efficient battery management on their boats. Awarded the 2010 IBEX Innovation Award, this advanced charging platform seamlessly integrates digital control and software-based power conversion technology to ensure your batteries are always in optimal condition, extending their life and maximizing performance while you enjoy extended time on the water.

ProMar Digital Performance Charging

The ProNauticP employs ProMar's cutting-edge Digital Performance Charging Platform, tailored specifically for the increasing use of 12-volt electronics in today's power, sail, cruising, and sport fishing boats. With twelve digitally-controlled charging profiles, you can effortlessly select the perfect setting to fully charge, condition, maintain, and re-condition your batteries, ensuring peak performance and longevity.

12 Selectable 4-Stage Charging Profiles

Choose from up to 12 precision 4-stage charging profiles including:

1. Charge
2. Condition
3. Maintain
4. Re-condition

Features include automatic dockside power mode for 12V DC lighting and appliances, with factory settings optimized for Flooded (Lead Acid) batteries and selectable options for AGM and GEL batteries.

Power Factor Correction & Global AC Input

Designed for worldwide compatibility, the ProNauticP features an auto-ranging power factor correction with a global AC input range of 100-250VAC/50-60Hz. This ensures reduced harmonic distortion and allows the charger to operate seamlessly off a standard household power outlet, consuming less power and making more AC power available on board.

Advanced Charging Technologies

Distributed On Demand Technology

Maximize your charging efficiency with the ability to automatically sense and distribute 100% of available charging amps to any single bank or combination of all banks, ensuring balanced and effective charging for all your battery banks.

Digital Self-Calculating Absorption & Battery Health Re-Conditioning

The ProNauticP intelligently programs conditioning time based on the discharge state of your batteries. After 21 days in maintenance mode, it automatically de-sulfates batteries, enhancing reserve power performance and significantly extending battery life.

Conservation Energy Saver Mode

Optimize energy usage with the Conservation Energy Saver Mode, which lowers float voltage after 72 hours of minimal load activity (less than 5 amps). This feature is applicable to both flooded and sealed charge profiles, ensuring energy conservation during storage periods.

Real-Time Monitoring & Diagnostics

Service and Fault Mode LED Indicators

Stay informed with real-time LED indicators that display wiring faults or adverse conditions that could impact your boat's charging system, allowing for quick diagnostics and troubleshooting.

Dual Digital Displays

Monitor your charging system with dual digital displays that show actual charging voltage and amperage in real-time, along with AC power-on diagnostics that provide pass or fail status and discreet fault indications for issues like mis-wiring or unfavorable battery bank conditions.

Efficient Cooling & Safety Features

Automatic Fan Speed Control

Experience quiet operation with innovative front exhaust design that prevents airflow restriction and optimizes cooling performance, ensuring your charger operates efficiently without unnecessary noise.

Temperature Compensation & Built-in Safety

The ProNauticP includes a remote temperature probe for automatic temperature compensation, ensuring safe and efficient charging under varying temperature conditions. Additional safety features include ignition protection, current limiting, and certifications including Marine ULc 1236, CE, CTick, and FCC Class B.
