From Arri Alexa35 webpage (see 'Technical Data'). https://www.arri.com/en/camera-systems/cameras/alexa-35 Power Input: 20.5 - 33.6 V DC Camera will accept any voltage between 20.5v and 33.6v. The power draw of the camera is listed as 90w, so even if your standard 14v sled batteries (2 combined for 24v mode) drop down to 20.5v, the Max amperage going though your sled is 4.4 amps (more than enough before tripping the 10 amp breaker). Note: This is just for the camera - not including any accessories you may also be powering. Yep - don't do this!

Hi Alberto, Usually, that 8pin monitor lemo on the bottom of sleds is for power and analogue video, not HD-SDI, and should be tied to the analogue input on your top stage. On your ACC port on the monitor, you can see pin 3 (Y/CVBS) is an analogue video input. So unless you're using an analogue outputted signal at your camera, eg film camera with sd tap, you can't send HD-SDI signals that way, so it's 2 cables I'm afraid!
