ProNauticP is Power Factor Corrected with auto-ranging global AC input allowing all models to operate off a standard household power connection. Featuring dual digital displays for real-time display of actual charging voltage and amperage and AC power-on diagnostics with pass or fail status in addition to discreet fault indication for mis-wiring or adverse battery bank conditions. 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 Connection Points: Periodically inspect and wipe AC input plug, DC battery leads, and terminal lugs to remove dust and corrosion — secure tight, clean connections improve charging reliability.
- Ensure Ventilation & Mounting: Install the unit in a dry, ventilated spot with space around it; proper airflow helps the automatic fan cooling operate quietly and prevents overheating.
- Inspect Cables & Wiring: Check AC and DC cables for wear, cracks, or looseness; replace damaged cables and retighten any loose terminals promptly to prevent voltage drop or faults.
- Monitor Charge Status: Use the digital displays and fault indicators to verify correct charge profiles and catch wiring or battery issues early.
- Avoid Moisture Exposure: Even with marine construction, keep the charger away from direct water spray — wipe off any condensation and keep connectors dry.
- Match Battery Types: Set the charger’s profile (Flooded, AGM, GEL, etc.) to match your battery chemistry for optimal conditioning and extended battery life.
