3.6 FLX power system DPR-2700
Introduction
The FLX Power System DPR-2700 consists of a chassis with two DC distribution shelves of three modular FLX Power Recti fi er
DPR-2700 units and a Control and Supervisory Unit (CSU). The FLX Power System DPR-2700 requires a nominal three phase AC
input of 230V (delta connection) or 400V (star connection), 50-60Hz.
The rear side of the power chassis has two power output ports (multi pole sockets) which provide in 16 (2 x 8) protected circuits with
a DC output of -54V.
One power output port of the FLX Power System DPR-2700 can power maximum 8192 FLX-24 pixels. The FLX Power System
DPR-2700 has two power output ports, so one FLX Power System DPR-2700 can power maximum 16384 FLX-24 pixels. This large
number of pixels can only be powered in case the total length of the power cables, from the power output port to the last FLX-24 pixel
in the connector string, is limited. Otherwise, the voltage drop over the power cables will be too high and because of this disabling
the last FLX-24 pixels in the string.

FLX Power Recti fi er DPR-2700
The FLX Power System DPR-2700 contains 6 removable (not hot swappable) FLX Power Recti fi er DPR-2700 units. One recti fi er
can deliver 2700 Watt (50 ampere DC). In case a recti fi er fails, the other recti fi ers remain delivering there maximum power. For
video applications with typical video content the FLX Power System DPR-2700 will run at average 30-40% of its maximum. So, in
case a recti
fi er fails it will probably not be visible during the event. The malfunction recti fi er can be replaced after the event.
