2. Installation.
2.1. Requirements.
The DC/DC converter is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required
for a given country) for step down
installations. The module should be mounted in confined spaces with normal relative humidity
(RH=90% maximum, no condensation) and temperature range from -
10°C up to +40°C. The module should operate in vertical position
in order to provide free and convectional air flow.
The module's load balance should be done prior to installation. During normal operation, the total current of the receivers
should not exceed
I=5A
while the power drawn from the module should not exceed
Pmax=60W.
Proper operation of the module requires adequate current capacity of the power source; the power supply capacity should be
calculated using the formula below:
P
IN
= 1,15 x
P
AUX
(
P
IN
= 1,15 x
I
AUX
x
U
AUX
)
Example:
The converter will supply the receivers with a capacity of
P
AUX
= 48W
drawing a total current of
I
AUX
= 4A
at the voltage
U
AUX
= 12V
. The minimum power supply capacity must therefore amount to
: P
IN
= 1,15 x 4A x 12V = 55,2W
.
The device should be mounted in a metal enclosure (cabinet). The rules for power supply, enclosures and shielding - according
to application - must be observed in order to meet the requirements of LVD and EMC directives.
