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 * 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 * 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 * Real time indication of wiring faults or adverse conditions that may impact the operation of a boat"s charging system * 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) * 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) * 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. * 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. * Real time indication of wiring faults or adverse conditions that may impact the operation of a boat?s charging system. * Up to 12 performance & precision 4-stage charging profiles: Charge, Condition, Maintain and Re-condition.
