Option: EnergyStar compliance for the entire display wall
When switched to standby, power consumption of the display when operated via the integrated AC power supply
(delivery default) is less than 700mW.
To bring the entire display wall to the level of EnergyStar compliance, every display needs to be connected to the
power net via a so-called switch unit.
All switch units are controlled by the Green Green BCM which serves as both, as switch controller and as Barco
Wall Control Manager.
When switching the entire display wall on, the command is executed with minimal delays on all display: it is
only during the zero crossing that the display is switched on. Thus the inrush current of the entire display wall is
rather low and does not require special safeguarding.
When switched to standby, a display wall managed by the Green BCM will consume minimal power and the
entire display wall is energy efficient as defined by the standards of the US EPA.
The Version 6.0 ENERGY STAR Displays specification covers computer monitors, digital picture frames, and profes-
sional signage, collectively referred to as "displays" under this specification. ENERGY STAR certified displays must
consume 0.5 watts or less in Sleep Mode and On Mode power requirements vary according to screen area and
resolution.
The 700mW mentioned above are fully compliant with the ENERGY STAR requirements since the 0.2W on top are
due to the1GB Ethernet connection.
The switch units (2) and the Green BCM (1) are mounted to a DIN Rail. The picture shows the arrangement for a
display wall consisting of 4 displays.
One Green BCM can control up to 50 displays. One Green peut contrôler jusqu'à 50 écrans.
A switch button to control the entire nxm matrix of switch units and the Green BCM is also available as an option.
