Key Features

• Three Isolated Outputs: Charges up to three independent battery banks simultaneously without interconnection, allowing flexible management of starter, house, and auxiliary systems.
• Advanced Multi-Stage Charging: Four-stage charging (bulk, absorption, float, standby) ensures complete charging, conditioning, and protection against overcharging.
• Wide Battery Compatibility: Supports multiple battery types including AGM, Gel, Flooded, Calcium, and LiFePO4 with 11 pre-set profiles plus a custom setting.
• Global Input Voltage Range: Operates from 80–270VAC, making it suitable for worldwide shore power or generator use.
• Power Factor Correction (PFC): High efficiency (>90%) reduces energy consumption, heat generation, and generator load while improving overall performance.
• Automatic Desulphation Mode: Periodically rejuvenates batteries to extend lifespan and maintain peak performance.
• Comprehensive LED Monitoring: 32-LED display provides real-time feedback on charging status, voltage, current, and system conditions.
• Programmable Power Reduction: Adjustable output levels (25–100%) allow operation on limited shore power or small generators while reducing noise.
• Temperature Compensation: Includes battery temperature sensing to optimise charging and protect batteries under varying conditions.
• Marine-Ready Construction: Compact, lightweight, and designed with corrosion-resistant materials and drip protection for marine environments.
