The Edison with the Arduino Expansion Board powered by a power supply supports 7V to 15V. Regarding the current, it often uses 500mA but it could use more than this (600mA ~750mA). The board will not draw more than 2A if you are concerned of using the power supply you posted above.
I’m currently using a power supply of 12V and 1.5A and it works great. If you are going to use a power supply of 9V and 2A you shouldn’t have problems.
