Votronic Automatic Charger Pb 1240 SMT 3B

• Charging programmes no. 1, 2, 4 and Li (gel, AGM, acid, LiFePO4) adjustable to battery type
• The charging voltage is free of peaks and regulated in such a way that the batteries cannot be overcharged.
• 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).
• Lithium LiFePO4? Maintenance, Auto Wake Up, maintenance phase: Regular automatic activation of battery cell balancing every 10 days to ensure that the battery is always fully charged.
• Lead battery regeneration twice a week during long downtimes to prevent harmful acid stratification.
• Parallel and buffer operation: The battery continues to be charged or kept fully charged 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 better full charging of the weaker battery in cold weather and avoiding unnecessary battery gassing and thus battery stress in summer temperatures.
  With LiFePO4 batteries, the battery temperature sensor is required for the function: It serves to protect the battery at high and especially at low temperatures below 0°C.
• Silent Run function: Noise-optimised operation at the touch of a button (night mode).
• Power supply unit 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)
