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.
