Victron SKI024100002 Skylla-i Battery Charger 24/100 (3) 230V Battery Charger

Skylla-i Battery Charger 24/100 (3) 230V Battery Charger

The Skylla-i (3) features 3 isolated outputs. All outputs can supply the full rated output current.

Features:

• Rugged - Aluminium epoxy powder-coated cases with drip shield and stainless steel fixings withstand the rigors of an adverse environment: heat, humidity, and salt air. Circuit boards are protected with an acrylic coating for maximum corrosion resistance. Temperature sensors ensure that power components will always operate within specified limits, if needed by automatic reduction of output current under extreme environmental conditions.
• Flexible - Next to a CAN bus (NMEA2000) interface, a rotary switch, DIP switches and potentiometers are available to adapt the charge algorithm to a particular battery and its conditions of use. Please refer to the manual for a complete overview of the possibilities. 
• Synchronized parallel operation - Several chargers can be synchronized with the CAN bus interface. This is achieved by simply interconnecting the chargers with RJ45 UTP cables. Note: Two output and three output chargers cannot be paralleled with each other. Please see the manual for details.
• The right amount of charge for a lead-acid battery: variable absorption time - When only shallow discharges occur the absorption time is kept short to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely recharged.
• Preventing damage due to excessive gassing: BatterySafe mode - If to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the Skylla-i will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached.
• Less maintenance and aging when the battery is not in use: Storage mode - The storage mode kicks in whenever the battery has not been subjected to discharge for 24 hours. In the storage mode float voltage is reduced to 2.2V/cell (26.4V for 24V battery) to minimize gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘refresh’ the battery. This feature prevents stratification of the electrolyte and sulphation, a major cause of early battery failure.
• To increase battery life: temperature compensation - Every Skylla-i comes with a battery temperature sensor. When connected, charge voltage will automatically decrease with increasing battery temperature. This feature is especially recommended for sealed lead-acid batteries and/or when important fluctuations in battery temperature are expected.
• Battery voltage sense - To compensate for voltage loss due to cable resistance, the Skylla-i is provided with a voltage sense facility so that the battery always receives the correct charge voltage.
• Suitable for AC and DC supply (AC-DC and DC-DC operation) - The chargers also accept a DC supply.
• Use as a power supply - As a result of the perfectly stabilized output voltage, the Skylla-i can be used as a power supply if batteries or large buffer capacitors are not available.
• Li-Ion (LiFePO4) ready - Simple charger on-off control can be implemented by connecting a relay or open collector optocoupler output from a Li-Ion BMS to the remote control port of the charger. Alternatively, complete control of voltage and current can be achieved by connecting to the galvanically isolated CAN bus port.
