Power usage
The power supply on the HD2000 is a 15W 5V @ 3A power supply. The HD2000 will use
approximately 2.1A of power when playing a 720p or 1080i MPEG2 HD source file. This implies that
there is 900mA of additional available power that can be used by peripherals connected to the HD2000.
The user should not connect up any combination of peripherals that will exceed 900mA draw. If more
than 900mA 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 900mA can be shared any way you like on the following connectors.
USB1 – 500mA max
USB2 – 500mA max
DB9 5V – 250mA
DB25 3.3V – 100mA
HDMI 5V – 55mA max
Each of 6 LED outputs on DB25 – up to 24mA each
Audio 1, 2, 3 – 200mA max (i.e. if you connect up 5Ohm headphones, then each audio connector can
output up to 200mA RMS)
