Description

The ChargeMaster Plus 12/50-3 is an all-in-one battery charger built for efficient, dependable charging in tough marine and mobile conditions. 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 50A at 14.25V, and automatic current distribution directs charge to the bank that needs it most. Pre-float functionality means you can combine batteries of different sizes without overcharging the smaller ones. Compatible with mains voltages and frequencies worldwide, the charger runs standalone as a plug-and-play unit or integrates fully into a MasterBus or CZone system.

Improved cooling keeps noise low across the entire power range, and the compact, galvanically isolated casing withstands high temperatures and significant voltage fluctuations.

Which battery types can the ChargeMaster Plus 12/50-3 charge?
It charges gel, AGM, flooded and lithium ion batteries using the 3-step+ method, and also offers a user-defined profile for other chemistries.
How many battery banks can it charge at once?
The 12/50-3 has up to three battery outputs and shares a total of 50A at 14.25V between them, with automatic current distribution based on each battery's condition.
Can I use it anywhere in the world?
Yes. It accepts a nominal input of 120/240V (80-275V) at 50/60Hz, so it works with mains voltages and frequencies worldwide.
Does it integrate with MasterBus or CZone?
Yes. It communicates over MasterBus, CZone and NMEA for full system integration, or can be used as a plug-and-play standalone charger.
What battery bank size is recommended?
Mastervolt recommends a battery bank size of 200 to 400 Ah for the 12/50-3.
