Designed to provide more time on the water enjoying what you like most... boating.

ProMar Digital Performance Charging

ProMar Digital Charging Performance - 12 Selectable Profiles
Up to 12 performance & precision 4-stage charging profiles: Charge, Condition, Maintain and Re-condition. Automatic dockside power mode for 12 Volt DC lighting and appliances. Factory set for Flooded (Lead Acid) batteries. AGM, GEL selectable.

Power Factor Correction - Global AC Input
Auto-ranging (100-250VAC/50-60Hz) global AC input with reduced harmonic distortion allowing all models to operate off a household power outlet connection. ProNauticP consumes less power so more AC power is available on board.

Distributed On Demand Technology
Automatically senses and distributes 100% of available charging amps to any one bank or combination of all banks.

Digital Self-Calculating Absorption and Battery Health Re-Conditioning Mode
Automatically programs conditioning time based on discharge state of batteries. Automatically de-sulfates batteries after 21 days in the maintain mode, improving reserve power performance & extending battery life.

Conservation Energy Saver Mode
After 72 hours of not seeing a load greater than 5 amps, float voltage will be lowered consuming less energy during storage periods. (for flooded & sealed charge profiles)

Service and Fault Mode LED Indicators
Real time indication of wiring faults or adverse conditions that may impact the operation of a boat's charging system.

Automatic Fan Speed Control
Quiet operation. Innovative front exhaust prevents restriction of air flow and cooling.

Automatic Temperature Compensation and Built-in Safety
Remote temperature probe included - Ignition protected and current limiting. Designed and constructed to: Marine ULc 1236, CE, CTick and FCC Class B.

Maintenance Tips

• Clean & Dry Connections: Periodically wipe AC input plug, DC output leads, and battery terminals to remove dust, salt, and corrosion — secure clean contacts improve charging efficiency.
• Ensure Proper Ventilation: Install the charger in a dry, ventilated space with clearance on all sides so automatic fan cooling can work effectively and prevent overheating.
• Inspect Cables & Wiring: Check AC and DC cables for wear, cracks, or corrosion; tighten loose terminals and replace damaged leads to prevent power loss or faults.
• Monitor Display & Fault Indicators: Use dual digital displays and fault LEDs to verify correct charge profiles and catch potential wiring/battery issues early.
• Match Charge Profile to Battery Type: Select the appropriate charge profile (Flooded, AGM, GEL, etc.) to maximize battery life and health.
• Avoid Moisture & Corrosion: Even with marine construction, avoid direct water spray on connections; wipe off moisture and consider a light corrosion inhibitor on exposed contacts.
