Description

The Mastervolt ChargeMaster 12/25-3 is a 12 V battery charger that guarantees fast and complete charging wherever you are. Using Mastervolt's innovative 3-step+ charging process, it charges batteries quickly and fully, helping them perform better and last longer, and it is suitable for any battery type including Lithium Ion. Three equal charge outputs deliver up to 25 A, allowing several battery banks to be charged simultaneously, and auto-ranging gives fully automatic operation on any mains supply from 90 to 265 V AC.

A clearly lit LED display shows charge current, charge voltage, charge phase and battery content, with three buttons for easy control. The charger connects to a MasterBus network with a single cable for central, local or remote monitoring, and can supply a constant DC output to power equipment even when no battery is connected. Solid metal-to-metal connectors with strain relief prevent corrosion and overheating.
