ASI071 Manual
9
5.2 Power consumption
ASI071 has one APS-C format sensor, the max power consumption is around 500ma@5V
which is nearly the maximum power supply of USB2.0. We recommend customer connect ASI071
through USB3.0 which can provide 1A@5V power. You also need a separate power supply to
power the cooler. We recommend using a 12V/3-5A or more DC adapter for cooler power supply
(2.1×5.5, center positive). Using a battery with 11-15V is also suitable for the cooler power supply.
ASI071 and USB hub is powered from 12V DC power supply if you connect it.
Here is a test result of the cooler power consumption of ASI071 camera. It only needs 0.5A to
cool the camera to 30℃ below ambient.
5.2 DDR Buffer
ASI071 Pro camera includes one 256MB DDR3 memory buffer to help data transfer more
stable and no amp-glow issue which is caused by the slow speed data transfer during reading out
under USB2.0 Port.
DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.
