Description
The ChargeMaster Plus 24/20-3 is an all-in-one 24V battery charger that delivers efficient, reliable charging in demanding marine and mobile environments. Mastervolt's 'Battery's Best Friend' architecture uses the fast and safe 3-step+ charging method, suiting gel, AGM, flooded and lithium ion batteries, with a user-defined profile for other chemistries.
Three outputs share a total of 20A at 28.5V, and automatic current distribution sends charge to the bank that needs it most. Pre-float functionality lets you combine batteries of different sizes without overcharging the smaller ones. Compatible with mains voltages and frequencies worldwide, the charger works standalone as a plug-and-play unit or integrates fully into a MasterBus or CZone system, reporting input quality, charger performance and battery voltage and temperature.
Improved cooling keeps noise low across the power range, while a compact, galvanically isolated casing handles high temperatures and significant voltage fluctuations.
