  • High charging capacity even with short ride
  • Significantly improved energy balance of the pension group
  • Excellent protection of the supply battery and the connected consumer against the sometimes very strong voltage fluctuations of dynamically regulated alternators in newer vehicles
  • On longer trips, the iU1ou2 charging technology achieves a full charge and an overload is excluded
  • Optimal charging characteristics for 4 battery types adjustable by battery selector switch (gel, acid/AGM1, AGM2, LIFEPO4)
  • Automatic, adjustable charging power ensures the priority loading of the starter battery by the alternator in the case of heavily loaded vehicle sector network and thus ensures the immediate starting capacity of the vehicle again
  • If consumption in parallel and buffer operation, the battery will continue to be loaded or fully received. The adaptation of the loading times automatically calculates and monitors the loading converter.
  • Built-in temperature compensation automatically ensures your own adaptation of the charging voltage that is independent of the alternator to the battery temperature and enables loading operation outside of the recommended LIFEPO4 battery temperatures below 5 ° C or above 35 ° C; Battery temperature sensor Art. 2001 is included
  • Easy installation, no intervention in the vehicle of the vehicle required, device is switched into the charging line to the supply battery.
  • Safety protection and protection against reversal, short circuit and backload
  • Connection for remote control Art. 2075, remote of the IP67 Art. 2081 or Charger State Monitor IP67 Art. 2082
  • Also prepared for operation with EBL (electrical block) and EVS (only VCC 1212-25 IUOU-LI and VCC 1212-45 iuou-Li).
  • Built -in on -cussion filter enables the problem -free parallel operation with solar systems, network chargers and other load sources on a battery
  • Galvanic isolation between insertion and output ensures excellent suppression of disturbances by absolute separation of the battery circles, for clean mass conditions on both sides even with long supply lines, safety in the error trap (no pushing 12V/24V or 24/12V possible) and avoids reliably unwanted Diapencies of backing the battery circles
  • Switch input for fully automatic operation (ignition, D+ engine runs) or optionally manually controlled by long -distance switches
  • The measurement input optionally enables the device to be used if necessary also a pure voltage control
  • The device application area also extends to a clean battery charge further away from the alternator in large vehicles, supporters, supply containers etc.

Also available in boats with the electronics protected from moisture!
