Power requirements and mounting challenges when operating the Alexa 65 camera on a Steadicam rig
What the thread found
- The Alexa 65 requires 24V power supply, with a safe operating range of 22V to 35V and draws approximately 200W continuous
- The Alexa 65 cannot be powered by 12V like other Alexa models
- An onboard Anton Bauer battery plate with built-in converter can supply the required 24V from a 12V battery
- External power through a rig must support 24V at up to 10 Amps
- The Alexa 65 has a different bottom plate configuration than standard Alexa models and is incompatible with standard Alexa Steadicam mounting plates
- A custom intermediate plate may be needed to adapt standard Steadicam plates to the Alexa 65 bottom configuration
- The Alexa 65 with typical cinema setup including batteries, monitor, motors, and accessories weighs approximately 56 pounds
Depends on
- Mounting plate compatibility issues were reported but solutions differed depending on specific plate manufacturers and spacer block availability
- One user mentioned their package included a dedicated Steadicam plate, suggesting solutions may vary by equipment configuration
- The weight specification is from a single production setup and may vary based on specific lens, accessories, and configuration choices
