Victron Energy VRLA charger Skylla-IP65 24 V Charging current (max.) 35 A

Skylla-IP65 (1+1): Two outputs for charging two battery banksThe Skylla-IP65 (1+1) has 2 separate outputs. The second output is intended for charging the starter battery. As a result, it is limited to 3 A and has a slightly lower output voltage for maintaining the charge of the normally full starter battery.Skylla-IP65 (3): Three full current outputs for charging 3 battery banksThe Skylla-IP65 (3) has 3 separate outputs. All outputs can supply the full rated output current.IP65 protectiveEpoxy powder coated steel housing and splash-proof. Withstands the challenges of a difficult environment: Heat, moisture and salty air. An acrylic coating protects the printed circuit boards against corrosion as best as possible. Temperature sensors ensure that the current components are always operated within the specified limits. Under extreme environmental conditions, the output current is automatically reduced if necessary.LC displayFor status monitoring and easy adjustment of the charging algorithms to a specific battery and its operating conditions.Can bus interface (NMEA2000)For connection to a CAN bus network, to a Skylla-i control panel or to the Color Control digital display.Synchronized parallel operationSeveral chargers can be connected in parallel and synchronized with the help of a CAN bus interface. This is achieved by simply connecting the chargers to each other via RJ45 UTP cables. The right amount of charge for a lead-acid battery: Adjusted constant voltage timeIf only weak discharges occur, the constant voltage time is kept short to avoid overcharging of the battery. After a deep discharge, the constant voltage phase is automatically extended to ensure that the battery is fully charged.Preventing damage from excessive gassing: The BatterySafe modeIn order to shorten the charging time, the aim is to achieve the highest possible charging current in conjunction with a high constant voltage. However, in order to avoid excessive gas development toward the end of the constant current phase, the Skylla-IP65 limits the speed of the voltage rise after the gassing voltage has been reached.Less maintenance and aging when the battery is idle: The storage modeThe storage mode is activated whenever no discharge has taken place within 24 hours. In storage mode, the charge retention voltage is then reduced to 2.2 V/cell (26.4 V for a 24 V battery) to minimize gas development and corrosion on the positive plates. Once a week, the voltage is increased back to the constant voltage threshold to 'refresh' the battery. This results in a kind of equalizing charge that prevents electrolyte stratification and sulphation - the two main causes of premature battery failure.Higher battery life due to temperature compensationA battery temperature sensor is supplied with each Skylla-IP65 device. The temperature sensor provides for a decreasing charging voltage when the battery temperature increases. This is particularly important for gel batteries or when high temperature fluctuations are expected at all times.Battery voltage sensorTo compensate for voltage losses due to cable resistances, the Skylla-IP65 has a voltage sensor in the charging circuit, so that the battery always receives the correct charging current.Use as a power sourceDue to the excellent control circuit, the Skylla-IP65 can be used as a power source with a perfectly stabilized output voltage, if no batteries or large buffer capacitors are available.Suitable for lithium-ion batteries (LiFePo4)A simple on/off control can be attached by connecting a relay or an optocoupler output with open collector from a Li-Ion BMS to the remote control connection of the charger. Alternatively, voltage and current can be fully controlled by connecting to the CAN bus connector.
