RED ONE 12V auxiliary power ports insufficient voltage and current capacity
15 years old. Gear and prices may have changed since.
What the thread found
- The 12V auxiliary 4-pin Lemos connectors on the RED ONE camera body back panel are rated for a maximum of 1.5 amperes per port and should not be relied upon for powering demanding accessories
- Attempting to power high-current accessories like wireless focus motors through the auxiliary ports can damage the camera's power board, resulting in expensive repairs
- Professional users recommend powering external accessories directly from an external battery plate using a P-Tap connector rather than using the camera's built-in auxiliary ports
- Low voltage readings from these ports may indicate an internal electronic fuse has been damaged from overcurrent, requiring factory service
Depends on
- The specific RED model discussed is the RED ONE
- The discussion references hire house practices in the UK which may not reflect manufacturer guidance
- No resolution was reached on whether settings adjustments in GPIO menus could resolve the issue
- The actual circumstances that damaged the power board in the original report are not fully detailed
