Skylla-IP65 Battery Charger
12 V/70 A and 24 V/35 A, input voltage range 90-265 V
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 3 A and with a
slightly lower output voltage, is intended to top up a starter battery
IP65 protection
Steel epoxy powder coated case. Withstands 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.
LCD display
For status monitoring and to easily adapt the charge algorithm to a particular battery and its conditions of use
CAN-bus interface (NMEA2000)
To connect to a CAN-bus network, to a Skylla-i Control panel or to the Color Control digital display.
Synchronised parallel operation
Several chargers can be connected in parallel and synchronised with help of the CAN-bus interface. This is achieved
by simply interconnecting the chargers with RJ45 UTP-cables
Preventing damage due to excessive gassing: the BatterySafe mode
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.
Less maintenance and aging when the battery is not in use: the Storage mode
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.
To increase battery life: temperature compensation
Every 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.
Battery voltage sense
In order to compensate for voltage loss due to cable resistance, the Skylla-IP65 is provided with a voltage sense
facility so that the battery always receives the correct charge voltage.
Use as a power supply
As a result of the excellent control circuit, the Skylla-IP65 can be used as a power supply with perfectly stabilized
output voltage 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 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.
