7.2 Changing the current limit level
The current limit can be adjusted with a potentiometer (R1) on the main PCB (see illustration 10) or with an optional
potentiometer (25k). While setting the maximum charging current, the output voltage should always remain 24Vdc.
The maximum charging current should never exceed the factory set value for that specific charger type.
It is advisable not to choose the charge current (which is the output current minus the supply current for a load
connected parallel to the battery) above 20% of the battery capacity in [Ah]. Due to the output voltage regulation the
charger may be connected permanently to the battery.
7.3 Diode splitter
A diode splitter can be connected to the Skylla 24/100 3-phase charger. The output voltage must be increased to
compensate for the voltage drop over the diode splitter. The "float" and "boost" voltages can be set separately by
adjusting R12 and R64. The output voltage should then be measured after passing through the diode splitter. The
voltages should be 28.5Vdc "boost" and 26.5Vdc "float".
Place 47 MF/40V capacitor on the output of the Skylla.
Do not use "+ - "sensing to compensate voltage drop over the diode
7.4 Factory settings
The factory settings for the Skylla 24/100 3-phase charger are:
jumper or potentiometer
R12
R64
7.5 Jumpers and Potentiometers
Jumpers are small removable connectors situated on the PCB. By placing and removing the jumpers various features
can be enabled or disabled. Illustration 12 shows how to set the jumpers.
Potentiometers are adjustable resistors. Turning the screw increases or reduces the values associated within the
potentiometer. These values may concern matters such as voltage, frequency or switch on sensitivity. The screw must
be turned by means of a screwdriver (No. 0). See also illustration 12.
