MASTERVOLT MASS CHARGER 24/25 DNV/EC/CSI 220-240V 4.5-3.0A OUTPUT

MASTERVOLT MASS CHARGER 24/25 DNV/EC/CSI 220-240V 4.5-3.0A OUTPUT

The Mastervolt Mass Charger 24/25 is the definitive choice for professional skippers and boat builders who demand absolute reliability, safety, and silent operation. This advanced 24-volt, 25-amp battery charger delivers powerful, multi-stage charging for your vessel’s service batteries, ensuring they are always ready for use.

Key Features & Benefits:

• Advanced Convection Cooling (Fan-Less Design): This charger features a robust, passive cooling system with no internal fan. This eliminates a common point of failure, ensures completely silent operation (ideal for living quarters), and prevents dust and moisture ingress, leading to superior long-term reliability in harsh marine environments.
• Fully Certified for Marine Use: Built to the highest safety and quality standards, the Mass Charger 24/25 carries the prestigious DNV (Det Norske Veritas) certification, along with CE and CSI marks. This guarantees its suitability for demanding professional and recreational marine applications.
• High-Efficiency Charging: With an efficiency rating exceeding 85%, it minimizes energy waste and heat generation. Its intelligent 3-stage+ (bulk, absorption, float) and 4-stage (including equalization) charging algorithms perfectly maintain and prolong the life of Lead-Acid, Gel, and AGM batteries.
• Robust & Durable Construction: Housed in a heavy-duty, corrosion-resistant casing, it is built to withstand the vibrations, humidity, and temperature fluctuations encountered at sea.
• Comprehensive Protection: Includes safeguards against overvoltage, short-circuit, overload, and reverse polarity. It is also protected from low and high ambient temperatures, ensuring safe operation in all conditions.
• Simple & Reliable Integration: Designed for continuous, unattended operation. Its straightforward installation and “set-and-forget” functionality make it a cornerstone of any vessel’s DC power system.
