What is ALEXA’s power draw?
The power draw of the ALEXA camera and viewfinder is about 85 W. The power supply should deliver an output of more than 90 W to power the camera and viewfinder sufficiently. Additional accessories such as lens motors will add an additional power draw. Except for the ARRI HDM-7, which draws relatively little power, it is recommended to power on-board monitors from an external source. Please note that using a 24 V power source is more efficient than using a 14.4 V source, as ALEXA uses 24 V internally.
