Color profile: Disabled Composite Default screen 1. DESCRIPTION 1.1 General All Victron Skylla 24/25, 24/50, 24/75 and 24/100 battery chargers are subjected to full functional testing before leaving the factory. They are properly packed for secure transportation. IP21= protection against materials larger than 12 mm (for example a finger) and protection against vertically descending waterdrops (condensation).
Color profile: Disabled Composite Default screen 1.3 Description The Skylla charger will charge the battery as soon as the power switch is turned on, provided there is a mains supply. If automatic charge mode is selected (see connection diagram), the battery will be charged with the built in IUoUo characteristic. The float voltage is factory preset to 26.5 V. The boost voltage is factory preset to 28.5 V. The boost and float voltages are user adjustable (see chapter 6).
Color profile: Disabled Composite Default screen 2. PROTECTION The Skylla charger is inherently safe due to its robust design and internal safety features. 2.1 short circuit current = current supplied when a shortcircuit on the output occurs. Short circuit protection The output current is fully short circuit protected. The output current is internally limited under all conditions (see specifications). The battery cables are thus protected in the event of a short circuit. 2.

Color profile: Disabled Composite Default screen 3. COMPENSATED CHARGING The Skylla has a temperature compensation facility which adjusts the charger voltage to the battery temperature. In order to use this facility, a temperature sensor (V.T.S.) must be fitted to the battery. This is because a higher charging voltage can be used with a cold battery than with a warm battery. The reference charging voltage is 28.5 V at a battery temperature of 20ºC (see illustration 1). 3.
Color profile: Disabled Composite Default screen 3.4 High battery temperature At battery temperatures of +50ºC and above, the charging voltage drops sharply. At values of 55ºC and above, the charger operates as a rectifier with an output voltage of 24 V (see illustrations 1, sections “C” and “D”). The plastic bag containing connection materials includes instructions showing where the temperature sensor must be fitted.
Color profile: Disabled Composite Default screen 4. INSTALLATION 4.1 Mounting Wall or floor mount the Skylla charger in a dry, well ventilated area. Excessively high ambient temperatures may adversely affect the output current and the lifetime of the Skylla charger. Best results are obtained in such conditions if the Skylla charger is wall mounted. For secure placement, the Skylla is supplied with mounting holes both in the rear and in the underside, see drawing sk02018e on page 34.

Position of earthing screw on the Skylla 24/25. 4.3.1 Earthing The Skylla charger is not a double insulated charger. The PE terminal must be connected to a true earth under all conditions. On a boat, the earth terminal on the under side of the housing must be connected to the ground plate or the hull.

Color profile: Disabled Composite Default screen 4.4 Remote control The Skylla charger can be equipped with a remote control unit, the Skylla Control (SKC, see illustration). The SKfront has LEDs displaying “charger on”, “boost” and “float” and a potentiometer to decrease the maximum charge current. The connections for the Skylla are made through a six wire cable, see drawing number SK02007E, page 36.

Color profile: Disabled Composite Default screen 5.2 “boost-float” cycle 5.2.1 “boost” period During the first part of the “boost” period, the “boost” LED is turned off and the batteries are charged with the maximum charging current. The battery voltage will increase until it reaches 28.5 volts, at which point the “boost” LED will light up. This marks the start of the second part of the boost period, which will last for 4 hours. During this period the charging current Illustration 4.
Color profile: Disabled Composite Default screen 6. CALIBRATION 6.1 Adjusting the charge voltage The float voltage is factory preset to 26.5 V. The boost voltage is factory preset to 28.5 V. The boost and float voltages are user adjustable. These values are recommended by almost all lead-acid battery manufacturers. The current and voltage settings do not have to be periodically checked.
Color profile: Disabled Composite Default screen 6.1.2 Setting the “boost” voltage While adjusting the charger voltages, the batteries should be well charged, the charging current should not exceed 5 Ampere. While adjusting the “boost” voltage, the charger should be in “boost” mode (the “boost” LED should be on). Connect a digital voltage meter, with a 0.1 Volt resolution, to the output. Adjust R64 until the required output voltage is reached. 6.1.3 Setting the “float” voltage Illustration 6.
Color profile: Disabled Composite Default screen 6.1.5 Adjusting charging voltage for 12 Volt batteries For use with 12 Volt batteries the jumpers S7 and S8 should be placed. The “boost” and “float” voltages will then be set automatically to, respectively, 14.25 Volt and 13.5 Volt. No adjustment is required. 6.1.
