  • High charging capacity even for short journeys
  • Significantly improved energy balance of the supply circuit
  • Excellent protection of the supply battery and the consumers connected to it against the sometimes very strong voltage fluctuations of dynamically controlled alternators in newer vehicles
  • For longer journeys, the IU1oU2 charging technology achieves a full charge and prevents overcharging
  • Optimal charging characteristics for 4 battery types adjustable by battery selector switch (gel, acid/AGM1, AGM2, LiFePO4)
  • Automatic, adjustable charging power ensures that the starter battery is primarily charged by the alternator when the vehicle's on-board network is heavily loaded, thus ensuring that the vehicle can be started again immediately
  • In the case of simultaneous consumption in parallel and buffer operation, the battery continues to be charged or is kept fully charged. The charging converter automatically calculates and monitors the adjustment of the charging times.
  • Built-in temperature compensation automatically adjusts the charging voltage to the battery temperature independently of the alternator and also enables charging outside the recommended LiFePO4 battery temperatures below 5°C or above 35°C; Battery temperature sensor item 2001 is included
  • Easy installation, no intervention in the vehicle's starter circuit required, device is connected to the charging line to the supply battery.
  • Safety protection and protection against reverse polarity, short circuit and reverse discharge
  • Connection for remote control Art. 2075, remote operating indicator IP67 Art. 2081 or Charger State Monitor IP67 Art. 2082
  • Also prepared for operation with EBL (electroblock) and EVS (only VCC 1212-25 IUoU-Li and VCC 1212-45 IUoU-Li).
  • Integrated on-board power supply filter enables problem-free parallel operation with solar systems, mains chargers and other charging sources on one battery
  • Galvanic isolation between input and output ensures excellent suppression of interference through absolute separation of the battery circuits, clean ground conditions on both sides even with long supply lines, safety in the event of a fault (no breakdown 12V/24V or 24V/12V possible) and reliably avoids unwanted reverse discharge of the battery circuits
  • Switching input for fully automatic operation (ignition, D+ engine running) or optionally controlled manually by a remote switch
  • Measuring input also enables pure voltage control of the device if required
  • The scope of the device also extends to clean battery charging further away from the alternator in large vehicles, trailers, supply containers, etc.

Also available in boat version with moisture-proof electronics!
