  • Loading programs No. 1, 2, 4 and Li (gel, AGM, acid, lifepo4) adjustable to battery type
  • The charging voltage is free of tips and regulated so that an overload of the batteries is excluded.
  • Fully automatic operation: The charger can be constantly connected to the battery and keeps it in full load. In the event of a network failure, the batteries will not be unloaded (separation by security switch).
  • Lithium LIFEPO4-MAINTENANCE, Auto Wake Up, maintenance phase: Regular automatic activation of the battery cell balancing every 10 days to ensure the full load of the battery.
  • Lead battery regeneration with long downtimes twice a week against harmful acidic layers.
  • Parallel and buffer operation: With simultaneous consumption, the battery is charged or fully received. The adaptation of the loading times calculates and monitors the charger automatically.
  • Monitoring-free charge: Multiple protection against overload, overheating, overvoltage, short circuit, polarity, misconduct and battery recharge through electronic stop to the complete separation of charger and battery with built-in safety switch.
  • Connection for battery temperature sensor (accessories temperature sensor 825, item no. 2001): In the case of lead batteries (acidity, gel, AGM), the charging voltage is automatically adjusted to the battery temperature, causes a better in cold Full loading of the weaker battery, in summer temperatures, unnecessary battery absorbing and thus battery stress is avoided.
    With LIFEPO4 batteries, the battery temperature sensor is required for the function: it serves battery protection at high and especially at low temperatures below 0 ° C.
  • Silent Run function: At the push of a button noise-optimized way of working (night operation).
  • Power supply function: enables consumers to be supplied without a battery (e.g. battery change).
  • Charging cable compensation: Tension losses on the charging cables are automatically excavated.
  • Construction network filter: Problem-free parallel operation with solar systems, wind and benzingen generators, alternators etc. on a battery.
  • Charging aid for low -level lead batteries: gentle invitation to the (lead -acid, -gel, -gm) battery up to 8 V, then powerful support of the battery with any still switched on consumers.
  • Separation of the batteries in the event of a power failure, overheating, misconduct (safety switch per charging output)
  • Separate side charging output "S" for the support and maintenance charge of the vehicle starter battery

Also available in boats with the electronics protected from moisture!
