Skylla-IP65 (1+1): two outputs to charge 2 battery banks

The Skylla-IP65 (1+1) features 2 isolated outputs. The second output, limited to approximately 3A trickle charge and with a slightly lower output voltage, is intended to top up a starter battery.

IP65 Rating Protection

With a steel epoxy powder coated case the Skylla is built to withstands the rigors of adverse environments such as 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.

Synchronised Parallel Operation

Several chargers can be connected in parallel and synchronised with help of the CAN-bus interface. This is achieved by simply connecting the chargers with RJ45 UTP-cables.

Variable Absorption - the right amount of charge for a lead-acid battery: 

When only shallow discharges occur the absorption time is kept short in order 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.

BatterySafe mode - Preventing damage due to excessive gassing

If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the Skylla-IP65 will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached.

Storage mode - Less maintenance and aging when the battery is not in use

The Storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the storage mode float voltage is reduced to 2,2 V/cell (26,4 V for 24 V battery) to minimise 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.

Li-Ion (LiFePO4) ready

Simple charger on-off control can be implemented by connecting a relay or open collector opto coupler 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 CAN-bus port.

Temperature Compensation - Increase battery life

The Skylla-IP65 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 of battery temperature are expected.
