A powerful, waterproof and intelligent battery charger with a 7-stage adaptive charging algorithm, suitable for a wide range of battery types and chemistries with a special lithium-ion charging algorithm.
The wide range of universal input voltage increases installation flexibility, the charger maintains its full output power regardless of where in the world it is located.
Thanks to its IP65 protection rating, this charger is particularly suitable for use in marine, mobile and industrial applications and can withstand adverse environmental conditions: heat, humidity and salt air.
Both models are available in two versions:
- 3 fully-fledged outlets
- 1 fully-fledged output together with an isolated 3 A trickle charge output for a starter battery
Models:
12V/70A & 24V/35A
Skylla-IP65 (3): three full current outputs for charging 3 battery banks
The Skylla-IP65 (3) has 3 separate outputs. All outputs can deliver the full rated output current.
IP65 protection
Epoxy powder-coated steel housing and splash-proof. Withstands the challenges of a difficult environment: heat, humidity and salty air.
An acrylic coating provides the best possible protection for the circuit boards against corrosion.
Temperature sensors ensure that the power components are always operated within the specified limits. Under extreme environmental conditions, the output current is automatically reduced if necessary.
LCD display
For status monitoring and easy adaptation 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 operation
Multiple 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: adapted constant voltage time
If only weak discharges occur, the constant voltage time is kept short to avoid overcharging the battery. After a deep discharge, the constant voltage phase is automatically extended to ensure that the battery is fully charged.
Prevention of damage due to excessive gassing: BatterySafe mode
The aim is to achieve the highest possible charging current in conjunction with a high constant voltage in order to shorten the charging time. However, to avoid excessive gassing towards the end of the constant current phase, the Skylla-IP65 limits the speed of the voltage increase after the gassing voltage has been reached.
Less maintenance and ageing when the battery is at rest: storage mode
Storage mode is always activated if 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) in order 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 creates a kind of equalizing charge that prevents electrolyte stratification and sulphation - the two main causes of premature battery failure.
Higher battery life through temperature compensation
A battery temperature sensor is supplied with every Skylla-IP65 device. The temperature sensor ensures that the charging voltage decreases as the battery temperature rises. This is particularly important for gel batteries or when constantly high temperature fluctuations are expected.
Battery voltage sensor
To compensate for voltage losses due to cable resistance, 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 source
Due 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 added by connecting a relay or open collector optocoupler output from a Li-Ion BMS to the remote control port of the charger. Alternatively, voltage and current can be fully controlled by connecting to the CAN bus port.
