The vcc 1224-25 IUoU from Votronic (mpn 3311) is a fully automatic, galvanically isolated battery charging converter for special vehicles, high-end motorhomes and boats with galvanic isolation. The charge converter (booster) of the "vcc" series has been developed according to the latest specifications for mobile charging of supply batteries (living space/onboard batteries), from the alternator (starter battery) while driving. The device provides a complete IU1oU2 charging characteristic even while driving. The max charge current of the vcc 1224-25 is 25a and it can work with lead acid, gel, agm1 and AGM2 batteries. This device charges a 24v battery from a 12v battery / alternator.

Unlike the conventional disconnect relay, the charging voltage is lowered or raised according to charging program specification, so it is especially good for EURO standard 6, 6 + plus vehicles.

Universally applicable multi-talent

For on-board batteries in classic lead-acid, lead-gel or lead-AGM technology, the selectable charging programs ensure a monitoring-free, rapid and gentle full charge from any state of charge with subsequent full maintenance and care of the battery. Even during short trips, the battery is charged with full charging current. Connected 12 V consumers are automatically supplied as well, even if the on-board network is heavily loaded. The automatic power control ensures the necessary safety and startability of the vehicle.

important features of the Votronic 3311 vcc 1224-25 IUoU

  • The vcc 1224-25 is b2b charger with galvanic isolation for charging 24v batteries from a 12v alternator / battery.
  • max. charging current: 25a, input voltage range 12v, charges 24v batteries, recommended battery capacity: 50 - 220 Ah
  • Increases or decreases the voltage to the necessary level to accurately charge the on-board battery with the optimal charging characteristic for it.
  • It fully compensates for line losses and alternator voltage fluctuations, such as those that occur constantly to a significant extent in Euro 6 vehicles (intelligent alternators).
  • Features compact design, light weight (high frequency switch mode technology) and power components with strong dimensions for safe operation.
  • Significantly improved energy balance of the on-board battery. No intervention in the starter circuit; the unit behaves like a powerful consumer on the alternator.
  • The supplied 24v consumers are protected against overvoltage and voltage fluctuations.
  • The charging voltage is free from peaks and regulated to prevent overcharging of the batteries.
  • Fully automatic operation: the device is constantly connected to the batteries and is automatically activated by the running alternator of the vehicle. When the engine is not running, the batteries are not discharged.
  • Parallel and buffer operation: in case of simultaneous consumption, the battery continues to be charged or kept full. The device automatically calculates and monitors the adjustment of the charging times.
  • monitoring-free charging: Multiple protection against overload, overheating, overvoltage, short circuit, malfunction and battery back discharge by electronic cut-off up to complete disconnection of device and battery.
  • Built-in on-board power supply filter: Problem-free parallel operation with other charging sources (ebl, chargers, motor and fuel generators, Solaranlagen) on one battery.
  • Charging cable compensation: Voltage losses on the charging cables are automatically compensated.
  • Connection for battery temperature sensor (sensor included in scope of delivery).
  • For lead batteries (acid, gel, agm), the charging voltage is automatically adjusted to the battery temperature. This causes a better full charge of the weaker battery in cold weather, in summer temperatures unnecessary battery gassing is avoided.

What added value does the use of a b2b charge converter offer me?

Charge converters ensure optimal and fast charging of the supply battery from the alternator while driving. In contrast to the simple cut-off relay, the charging voltage is raised to the value that is necessary for the respective battery type for a full charge and is required by the battery manufacturers. This means that the full charging current can flow and already charge considerable amounts of current into the battery in a short time. Long charging lines and losses are neatly compensated for, as are voltage fluctuations at the alternator. In the case of charge converters with different input and output voltages (12v/24v or 24v/12v), the simple charging of a second battery is also possible without installing a second alternator.

The charge converters thus provide the well-known high quality of battery charging of the votronic chargers even while driving. The intelligent microprocessor charge control with "IU1oU2oU3" charging characteristics and dynamic charging time calculation automatically ensures the fast and gentle full charge as well as subsequent charge retention of the connected batteries from any state of charge and always allows the simultaneous co-supply of consumers in parallel to the supply battery.
