- Product description
- Charging programmes no. 1, 2 and 4 (gel, AGM, acid) adjustable to battery type
- The charging voltage is free of peaks and regulated in such a way that overcharging of the batteries is ruled out.
- Fully automatic continuous operation: The charger can be permanently connected to the battery and keeps it fully charged. In the event of a mains failure, the batteries are not discharged (disconnection by safety switch).
- Lead-acid battery regeneration twice a week during long periods of non-use to prevent harmful acid stratification.
- Parallel and buffer operation: The battery continues to be charged or is kept full during simultaneous consumption. The charger automatically calculates and monitors the adjustment of the charging times.
- Monitoring-free charging: Multiple protection against overload, overheating, overvoltage, short circuit, polarity reversal, incorrect behaviour and battery back-discharge through electronic cut-off up to complete disconnection of charger and battery through built-in safety switches.
- Connection for battery temperature sensor (accessory temperature sensor 825, art. no. 2001): With lead batteries (acid, gel, AGM), the charging voltage is automatically adjusted to the battery temperature, ensuring a better full charge of the weaker battery in cold weather and avoiding unnecessary battery gassing and thus battery stress in summer temperatures.
- Silent Run function: Noise-optimised operation at the touch of a button (night operation).
- Power supply function: Enables consumers to be supplied without a battery (e.g. battery replacement).
- Charging cable compensation: Voltage losses on the charging cables are automatically compensated for.
- Built-in on-board power supply filter: Problem-free parallel operation with solar systems, wind and petrol generators, dynamos 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.
- Disconnection of the batteries in the event of mains failure, overheating, malfunction (safety switch per charging output)
- Separate auxiliary charging output "S" for supporting and trickle charging the vehicle starter battery
- Built-in charging current distributor with 2 main charging outputs, each with maximum current and power capacity
- Charging current distributor optionally switchable to separate charging programme for starter battery
- Starter battery is also charged with full charging current if required (short vehicle service life)
- Battery capacity adjustable in 4 stages (12 charging programmes in total)
- Inputs for voltage sensor (sense) cables, can optionally be used with extra-long charging cables and/or external, lossy diode charging current distributors
- Mains/charging power can be reduced for low-power or limited mains supply, e.g. weakly fused shore power supply, generator operation, etc. (power limit function)
Optional accessories:
- Remote control S (Art. 2075)
- Remote operating display IP67 (Art. 2081)
- Charger State Monitor IP67 (Art. 2082)
- Temperature sensor 825 (Art. 2001)
