Boost-Charging A preliminary stage designed to improve battery health and recover lost capacity, particularly beneficial for older batteries. Desulphation / Recovery This stage actively breaks down sulfation that can occur in batteries left discharged, helping to restore them to full charge. Float Charging Maintains the battery at full capacity with a safe, constant voltage, preventing overcharging during long-term connection. Power Pack Function Provides a direct 24V DC power supply to a load (e.g., a 24V fridge) even when no battery is connected, useful during battery replacement or maintenance. Typical Applications Application Description Motorhomes & Caravans Reliable charging for leisure vehicle service batteries when connected to campsite hook-ups or domestic mains. Boats & Marine Vessels Maintaining 24V marine battery banks while docked or connected to shore power. Off-Grid & Backup Systems As a primary or backup charger for 24V battery banks in small off-grid setups or emergency power systems. Workshop & Garage Use Charging and maintaining 24V batteries for various equipment, vehicles, or standby power. Built-In Protection Functions This Photonic Universe battery charger incorporates multiple safety features for reliable, unattended operation. It includes protection against DC short circuit, overheating, and overcharging, ensuring the safety of both the charger and your battery bank. The charging voltage is designed to be free from peaks, providing smooth and uninterrupted power delivery. An isolated DC output further enhances safety during use. Common Questions What battery types are compatible with this charger? This charger is compatible with 24V Lead Acid batteries, including AGM, Gel, and traditional Wet cell batteries. Can I charge multiple batteries simultaneously? Yes, you can charge a single 24V battery or multiple 24V batteries connected in parallel. It is crucial that all batteries connected in parallel are of the same type, capacity, and age for safe and efficient charging. What is the 'Power Pack Function'? The Power Pack Function allows the charger to provide a direct 24V DC power supply to a load, such as a 24V fridge, even when no battery is connected. This is useful for powering devices directly or during battery replacement. Does it have protection against overcharging? Yes, the unit features inbuilt safety functions, including protection against overcharging, allowing it to be left connected to the battery for unattended automatic charging without risk. Installation Notes Ensure adequate ventilation around the charger to prevent overheating. Connect the charger to a grounded 220-240V AC mains supply using the supplied UK 3-pin plug. Always connect the DC battery cables with correct polarity (+ to + and - to -). For permanent installations, ensure wiring complies with local electrical regulations. Refer to the user manual for detailed wiring and operational instructions. Before You Buy Verify your battery bank voltage is 24V. Confirm your battery type is Lead Acid (AGM, Gel, or Wet cell). Check the suggested battery capacity (40-300Ah) aligns with your battery bank. Consider your installation environment and ensure sufficient space for the charger's dimensions. For parallel battery connections, ensure all batteries are identical in type, capacity, and age. All specifications are based on manufacturer data and verified product information. Always consult the supplied user manual for complete details and safety guidelines. This product is covered by a 1-year manufacturer warranty.
