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
