Powering a Blackmagic HDMI-SDI converter box from a Steadicam battery via a 3-pin Lemo connector
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- The Blackmagic converter box requires either 12V regulated power or can accept a wider voltage range depending on the model version.
- Older Blackmagic converter models require 12V regulated power specifically.
- Newer Blackmagic converter models with milled aluminum housings can accept a wider range of voltages from 12V to 31V DC.
- The Blackmagic converter uses a 2.5mm DC barrel connector for power input.
- A 3-pin Lemo to DC barrel power cable can be sourced to connect a Steadicam battery to the converter.
- The specific model and revision of the Blackmagic converter determines its power requirements, so consulting the unit's specifications is necessary.
- Some users had reliability issues with certain Blackmagic converter models and switched to alternative solutions like AJA.
Depends on
- The voltage compatibility varied across Blackmagic converter revisions, making it essential to check the specific model's technical specifications.
- One user reported failures with three units before switching brands, suggesting potential reliability concerns with some versions.
- The discussion did not conclusively establish whether all converter models use the same 2.5mm barrel connector size.
- It remains unclear whether a GH4 camera battery alone provides sufficient power without additional regulation for all converter models.
