Votronic Automatic Charger Pb 2425 SMT 3B

• 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 excluded.
• Fully automatic continuous operation: The charger can be permanently connected to the battery and keeps it fully charged. In case of mains failure, the batteries are not discharged (disconnected by safety switch).
• Lead-acid battery regeneration twice a week during long periods of inactivity to prevent harmful acid stratification.
• Parallel? and buffer? operation: In case of simultaneous consumption, the battery continues to be charged or kept full. 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, faulty operation and battery reverse discharge by electronic cut-off up to complete disconnection of charger and battery by built-in safety switches.
• Connection for battery temperature sensor (accessory temperature sensor 825, art. no. 2001): For lead batteries (acid, gel, AGM), the charging voltage is automatically adapted to the battery temperature, resulting in a better full charge of the weaker battery in cold weather, and in summer temperatures, unnecessary battery gassing and thus battery stress is avoided.
• Silent Run function: noise-optimised operation at the touch of a button (night operation).
• Power supply function: Enables consumers to be supplied without battery (e.g. battery change).
• Charging cable compensation: Voltage losses on the charging cables are automatically compensated.
• 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 of the battery with consumers that may still be switched on.
• Disconnection of the batteries in case of mains failure, overheating, malfunction (safety switch for each charging output).
• Separate secondary charging output "S" for support and maintenance charging of the vehicle starter battery.
• Built-in charging current distributor with 2 main charging outputs, each with max. 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 can be set 4 times (total of 12 charging programmes)
• Inputs for voltage sensor (sense) cables, optionally usable with overlong charging cables and/or external, lossy diode charging current distributors
• Mains/charging power can be reduced in case of low-power or limited mains supply, e.g. weakly fused shore power, generator operation, etc. (power limit function)

Optional accessories:

• Remote control S (art. 2075)
• Remote operating display IP67 (item 2081)
• Charger State Monitor IP67 (Art. 2082)
• Temperature sensor 825 (art. 2001)
