1. Technical description.
1.1.General description.
The DCDC converter is used for powering devices that require stabilized voltage of 12V DC. The maximum
current load is 1A (Pmax= 12W).This module does not have galvanic insulation between the input and output
(IN-AUX), and operates on a common ground potential. The unit is protected against short circuit, overload and
overheating.

1.3. Accessories.
For the converters are available accessories - cable adapter. For details –visit www.pulsar.pl.
2. Installation.
2.1. Requirements.
The converter shall be mounted by the qualified installer having appropriate (required and necessary for a given
country) permissions and qualifications for connecting (operating) low-voltage installations. The unit should be mounted in
confined spaces, in accordance with the 2nd environmental class, with normal relative humidity (RH=90% maximum,
without condensation) and temperature from -10°C to +40°C.
In order to meet the LVD and EMC requirements, the rules concerning: supply, development and shielding ought
to be followed - accordingly to the application.
2.2. Installation procedure.
1. Fit the converter inside the device.
2. Connect the converter input cables to the DC voltage source, according to polarity.
3. Connect the converter output cables to the load.
4. After the performance of test and function checks, close the case, cabinet, etc.
3. Maintenance.
Any and all maintenance operations may be performed following the disconnection of the converter from the
power network. The converter does not require any specific maintenance procedures, however, in the case of significant
level of dust, it should be cleaned with compressed air.
WEEE marking
According to the EU WEE Directive – It is required not to dispose of electric or electronic
waste as unsorted municipal waste and to collect such WEEE separately.
