Newmar Phase Three PT-24-45U 24V 45A Marine Battery Charger
24V 45A Newmar PT charger with three-stage charging and selectable lead-acid profiles.
Marine three-stage battery charger with bulk, absorption and float operation, selectable wet/AGM/gel charging and multiple isolated outputs. Intended for permanent onboard installations where charging reliability matters. This 24V, 45A model has 3 charging outlets and suits the catalog-listed 90–450 Ah battery capacity range. Verify AC supply requirements by model because some PT units have limited or selectable AC voltage ranges.
For installation, confirm the charger’s output-bank arrangement, battery chemistry, shore-power supply and cable protection against the vessel’s system design.
