Product description
The DC-DC converter MAGIC converts a DC-
voltage into another stabilized DC-voltage with a
full galvanic isolation between the input and
output.
Applications
It offers you the following applications (see
drawings "INSTALLATION"):
MAGIC 24/12-20A
• a stabilized 12V DC power supply / single
stage float charger (e.g. to supply 12V
equipment from a 24V system), or
• a three-stage battery charger to charge a 12V
battery from a 24V system fully automatically,
or
• a dimmer for 12V lights.
• a 24/36 converter without galvanic isolation,
where the input is connected in series with
output.
•
MAGIC 24/24-20A
• a 24VDC stabilized DC power supply / single
stage float charger (e.g. for a galvanic
isolation of the vehicle's electrical system)
• a 24/48V converter without galvanic isolation,
where the input is connected in series with
output.
• a dimmer for 24V lights
MAGIC 12/12-20A
• a 12VDC stabilized DC power supply / single
stage float charger (e.g. for a galvanic
isolation of the vehicle's electrical system)
• a dimmer for 12V lights.
MAGIC 12/24-10A
• a 24V stabilized DC power supply / single
stage float charger (e.g. for a galvanic
isolation of the 24V system), or
• a 12/36V converter without galvanic isolation,
where the input is connected in series with
output.
Settings
There is no need to change the settings if the
converter is used as a stabilized DC power supply.
Inside the converter four DIP switches can be
found to adjust the converter according to your
personal preferences. (see table "DIP SWITCH
SETTINGS").
To adjust the DIP switches, proceed as follows:
1. Be sure the converter is disconnected from
any power source;
2. Remove the back cover of the converter by
loosen the four screws (see drawing
"DIMENSIONS");
3. Use a small flat-blade screw driver to change
the DIP-settings;
4. Remount the back cover again.

ENGLISH
When more converters are paralleled to increase
the total output current, DIP-switches 1, 2 and 4
must be set to the "OFF"-position and DIP-switch
3 depended to the preferred output voltage.
Installation
• Be sure that the output of the supplying source
is switched off during installation. Also be sure
that no consumers are connected to the
batteries during installation, to prevent
hazardous situations.
• Check that the battery voltage is the same as
the converter's input voltage (e.g. 24V battery
for a 24V input voltage). Also check that the
output voltage satisfies loading requirements
• Due to possible moisture accumulation and
optimal heat discharge, the converter must be
installed in a well-ventilated room protected
against rain, vapour, moisture and dust. We
advise to mount the unit in a vertical position
with the connecting cables downward.
• Integrate a fuse in the positive wiring and
place it nearby the battery. See specifications
for the recommended fuse.
• Do not install the DC-DC converter straight
above the batteries because of possible
corrosive sulphur fumes.
Connections
For correct connection - see drawings
"INSTALLATION".
• Use reliable cord end terminals to fix the wires
to the DC-input and –output.
• See specifications for the recommended wire
size.
• To minimize any EMC-interference we advise to
connect the negative pole of the supplying
battery to the ground.
Connect a momentary switch between the
"switch"-connection and the DC-output ground if
you want to use the remote switch function
and/or the light dimmer function (see drawing 1B,
2B, 3B).
