  • Charging programs no. 1, 2, 4 and Li (gel, AGM, acid, LiFePO4) adjustable to battery type
  • The charging voltage is peak-free and regulated in such a way that the batteries cannot be overcharged.
  • Fully automatic continuous operation: The charger can be constantly connected to the battery and keeps it fully charged. In the event of a power failure, the batteries are not discharged (separation by safety switch).
  • Lithium LiFePO4- Maintenance, Auto Wake Up, maintenance phase: Regular automatic activation of the battery cell balancing every 10 days to ensure that the battery is fully charged.
  • Twice a week lead-acid battery regeneration during long standstill periods to prevent harmful acid stratification.
  • Parallel and buffer operation: If the battery is consumed at the same time, it continues to be charged or is kept full. The charging times are automatically calculated and monitored by the charger.
  • Charging without monitoring: Multiple protection against overload, overheating, overvoltage, short circuit, polarity reversal, incorrect behavior and reverse battery discharge through electronic regulation up to complete separation of charger and battery through built-in safety switch.
  • Connection for battery temperature sensor (temperature sensor 825 accessory, item no. 2001): With lead batteries (acid, gel, AGM), the charging voltage is automatically adjusted to the battery temperature In the cold, the weaker battery is better fully charged, and unnecessary battery gassing and thus battery stress are avoided in summer temperatures.
    With LiFePO4 batteries, the battery temperature sensor is required for the function: It protects the battery at high and especially at low temperatures below 0°C.
  • Silent run function: noise-optimized operation at the touch of a button (night mode).
  • Power pack function: Allows the consumers to be supplied without a battery (e.g. changing the battery).
  • Charging cable compensation: Voltage losses on the charging cables are automatically compensated.
  • Built-in on-board network filter: Problem-free parallel operation with solar systems, wind and petrol generators, alternators, etc. on one battery.
  • Charging aid for deeply discharged lead batteries: Gentle pre-charging of the (lead-acid, -gel, -AGM) battery up to 8 V, then powerful support for the battery if consumers are still switched on.
  • Battery disconnection in the event of a power failure, overheating, malfunction (safety switch per charging output)
  • Separate secondary charging output "S" for support and trickle charging of the vehicle starter battery

Also available in boat version with moisture-proof electronics!
