Mastervolt ChargeMaster Plus 80A 24v Output 120/230V Inp

The Mastervolt ChargeMaster Plus 24/80-2 Czone is a compact, high-performance multi-charger designed for modern boats and mobile power systems. It combines two outputs, a built‑in DC‑DC converter, a current limiter, and a VSR into a single unit that can charge multiple battery banks while underway. With MasterBus, CZone and NMEA communication, this charger talks to displays, shunts and power systems for smarter, safer charging wherever you are in the world.

Key benefits

• Two outputs in one—a primary high‑current output and a secondary output tailored for auxiliary batteries, allowing fast, safe charging of multiple batteries without extra hardware.
• Versatile battery compatibility—charges Lithium Ion, Gel, and AGM batteries, as well as large or small bank configurations, all from a single charger.
• World‑class charging performance—unlimited operating range of 80–275 V AC, 35–70 Hz, and a best‑in‑class 3‑step+ charging method that adapts to battery chemistry for longevity and efficiency.
• Efficient, safe operation—features Safe Charge with rapid State of Charge recognition to protect battery life, plus 20% more output at 14.4 V and 80% charging power at high temperatures (60 °C).
• Integrated power management—built‑in DC‑DC converter, current limiter and a VSR mean fewer components, less wiring, and simpler installation.
• Global compliance—CE, ABYC, UL, SAE, CEC and RCM/C‑Tick compliant, designed for marine and mobile environments with robust reliability.
• Smart communication—MasterBus, CZone and NMEA compatibility enables seamless communication with displays, shunts and power systems, including FireCan and CANopen networks.
• Easy to install and operate—compact footprint, sturdy connections, clear LED charge phase display, and an intuitive setup that reduces install time.
