Votronic 3305 VCC 2412-45 IUoU-Li B2B-lader

• 4 selectable programs - AGM/Gel/Lead Acid, LiFePO4
• Unattended charging through multiple protection functions
• Automatic, adjustable power control

The maximum charging current of the device is 45A and efficiently charges auxiliary batteries with lead-acid, lead-gel, lead-AGM or LiFePO4 technology from the alternator while driving. In contrast to conventional split-charge relays, the charging voltage is adjusted for long cables or small cross-sections to minimize losses. Even with 24V input voltage, 12V batteries can be charged without an additional alternator. Thanks to intelligent microprocessor charging control and "IU1oU2" charging characteristics, fast, gentle and complete charging is ensured. At the same time, 12V consumers can be supplied without overcharging or excessive gassing of the batteries. Furthermore, the charging voltage is free of spikes and regulated so that overcharging of the batteries is excluded.

• Galvanic isolation between input and output
• Fully automatic operation
• Built-in vehicle electrical system filter

In contrast to a simple split-charge relay, the charging voltage is raised to the value required for a full charge for the respective battery type and demanded by the battery manufacturers. Thus, the full charging current can flow and considerable amounts of current can be charged into the battery in a short time. Long charging cables and losses as well as voltage fluctuations at the alternator are cleanly regulated.

Integrated protection functions - reverse polarity protection, short-circuit protection, reverse discharge protection, safety timer per charging phase I/U1, safety shutdown on overheating, gradual reduction of charging power at overtemperature

Automatic and adjustable power control - Prioritizes charging of the starter battery by the alternator when the vehicle electrical system is overloaded. This ensures the immediate starting capability of the vehicle.

Parallel and buffer operation - During simultaneous consumption, the battery remains charged or is fully maintained. The charging converter calculates and monitors the charging times automatically.

Galvanic isolation - Absolute separation of the battery circuits even in the event of a fault (particularly relevant for 24V/12V mixed operation) and stable ground conditions even with long supply lines.

Lead temperature compensation - The temperature sensor automatically adjusts the charging voltage to the battery temperature. In cold conditions, it enables optimal full charging of weaker batteries, while in summer temperatures it prevents unnecessary battery gassing.

• Universally applicable multi-talent

Even on short journeys, the battery is charged with full charging current. Connected 12V consumers are automatically supplied, even when the vehicle electrical system is heavily loaded. The automatic power control ensures the necessary safety and starting capability of the vehicle.
