BrightSign Compact

Power usage

The power supply on the Brightsign Compact is a 15W 5.2V @ 3A power supply. The Brightsign
Compact will use approximately 1A of power when playing a 720p or 1080i MPEG2 HD source file. 1A
at 5.2V is about 5W.
This implies that there is 2A of additional available power that can be used by peripherals connected to
the Brightsign Compact. The user should not connect up any combination of peripherals that will exceed
2A draw. If more than 2A is drawn, then the external power supply will shut down due to overcurrent
conditions. The unit will not be damaged, but it may cause the unit to reboot or to not operate properly
until the overload is removed.
This 2A can be shared any way you like on the following connectors.
Ethernet – About 180mA when transferring data
USB – 1500mA max (USB spec is 500mA, but we decided to put out more current on the USB connector
just like some PCs do, in order to be able to use the Brightsign Expander in some cases without an
additional 5V power supply).
DB9 5V – 500mA
DB25 3.3V – 500mA
HDMI 5V – 55mA max
Each of 6 LED outputs on DB25 – up to 24mA each
IR Blaster output – Up to 24mA
