Product description
Votronic VCC 1224-25 - 3343 – Powerful DC-DC Converter for Optimal Battery Charging
The Votronic VCC 1224-25 - 3343 DC-DC converter is the perfect solution for efficiently charging 24V leisure batteries from a 12V starter battery system while driving. As the successor to the Votronic 3311, it features larger connection terminals and state-of-the-art technology for reliable and fast battery charging.
Main Features
- Efficient battery charging: Boosts the voltage to the optimal level required for fully charging the battery while reducing charging losses.
- High-quality IU1oU2 charging technology: Intelligent microprocessor control ensures gentle, fast charging followed by maintenance charging.
- Voltage stabilization: Compensates for losses in long charging cables and voltage fluctuations from modern alternators.
- Easy installation: No modification to the starter circuit required – the converter is integrated directly into the charging cable to the leisure battery.
- Flexible application: Suitable for lead-acid, gel, and AGM batteries with individually adjustable charging profiles.
Product Benefits
- High charging capacity: Even on short journeys, considerable amounts of current are fed into the battery.
- Improved energy balance: Protects the leisure battery from voltage fluctuations and increases the lifespan of the connected devices.
- Parallel buffer operation: Battery charge is maintained even when simultaneously used by connected devices.
- Galvanic isolation: Reliably protects against interference and back-feeding between input and output.
- Versatile applications: Ideal for large vehicles, trailers, leisure containers, or parallel operation with solar systems and mains chargers.
