Mastervolt ChargeMaster Plus 30A 24v Output 120/230V Input C-Zone MasterBus NMEA

The Mastervolt ChargeMaster Plus 30A 24V Output 120/230V Input C-Zone MasterBus NMEA is a dual-voltage battery charger engineered for serious vehicle builders and marine technicians managing multi-battery auxiliary systems. Whether you're integrating auxiliary power into a modified truck, RV, or marine vessel, this charger bridges standard household AC power (120V or 230V) to your 24V battery bank with intelligent automation. It's designed for installers who demand reliable power conditioning without the noise and heat signature that ruins engine compartment temperatures and drains parasitic loads.

This unit delivers 30 amps of regulated 24V DC output and incorporates Mastervolt's proprietary improved cooling technology—a critical detail that enables continuous full-load operation while maintaining extremely low acoustic output across the entire power range. The charger functions as a standalone converter or integrates seamlessly into larger C-Zone networked systems via MasterBus connectivity and NMEA protocol support, allowing you to monitor charge status, voltage regulation, and fault diagnostics from a centralized display. Three-stage charging (bulk, absorption, float) ensures battery longevity by preventing overcharge damage while maximizing charge acceptance during high-demand auxiliary system operation.

Heavy-duty vehicle modifiers, expedition overlanders, and commercial fleet operators benefit most from this charger when powering secondary 24V banks for winches, air compressors, auxiliary lighting, and integrated control systems. The dual input voltage flexibility (120/230V) makes it equally at home in North American garages and international installations. At 5.5 lbs, its compact footprint suits tight engine bay configurations, while its networked architecture eliminates voltage drops and simplifies multi-device power sequencing—essential when managing voltage-sensitive auxiliary modules that demand stable supply.
