48Vdc, the milestone
In the lighting sector, the
“downsizing” trend has gone
through a turning point which
took place when a new paradigm
broke out: low voltage. Mainly
applied in tracking systems,
it has implied the increase and
generalization of the use of
48Vdc, replacing the voltage
of domestic electrical networks
(between 110Vac and 240Vac,
depending on the region of
the world).
Choosing to supply the tracks
with 48Vdc means using a single
AC / DC power source for the
entire system, which frees each
luminaire from having to be
equipped with a driver that fulfills
this function individually. In this
way, for each piece, the number of
components needed is reduced,
as well as their size... And the design
is not limited anymore by many
restrictions that prevented the
miniaturization of the luminaires.
