Description
The ChargeMaster Plus 24/60-3 is a 24 V multi-charger that brings together several functions in one unit, replacing auxiliary chargers, battery isolators and a VSR to reduce system complexity and cost. Its 'Battery's Best Friend' architecture charges a wide range of chemistries, sizes and voltages with the fast and safe 3-step+ method, delivering up to 60 A across three battery connections. Smart features include Revival mode for fully depleted batteries, Priority Charge that sends power to the lowest battery first, and a Smart Input that lets all three batteries charge from a single alternator while underway.
An integrated VSR funnels alternator energy to the batteries, and the 24 V model can charge a 12 V starter battery without extra components. Native MasterBus, CZone and NMEA 2000 communication, combined with a very wide 80-275 V AC operating range and high-temperature tolerance, make it ideal for both standalone use and complete system integration in demanding marine and mobile environments.
