ENVIRONMENTAL AND POWER USAGE
The HD120, HD220, and HD1020 players are designed to be used between 0°C and 40°C, at 90% maximum relative
humidity, non-condensing.
The power supply on the BrightSign HD series is 15 W and 5.0 V at 3 A. These players will use approximately 1 A of
power when playing a 720p or 1080i MPEG2 HD source file.
Note: 1 A at 5.0 V is approximately 5 W.
There is 2 A of additional available power that can be used by peripherals connected to a player. Do not connect any
combination of peripherals that will exceed 2 A of draw. If more than 2 A is drawn, then the external power supply will shut
down due to overcurrent conditions. The unit will not be damaged, but it may reboot or not operate properly until the
overload is removed.
The remaining 2 A can be shared in any way among the following connectors:
Connector Power Usage
Ethernet Approx. 180 mA (when transferring data)
USB Max 1500 mA*
DE9 5V 500 mA
DB25 3.3V 500 mA
HDMI 5V Max 55 mA
6 LED outputs on DB25 Up to 24 mA (each)
*The USB spec is 500mA, but more current has been placed on the USB connector to be able to use the BrightSign
Expander, in some cases without an additional 5V power supply.
