Blackmagic SDI to Analog downconverter power supply voltage compatibility and solutions
14 years old. Gear and prices may have changed since.
What the thread found
- The Blackmagic SDI to Analog downconverter has a maximum input voltage of 12V and will not power on when supplied with typical camera battery voltages around 14.4V or higher.
- The unit will operate correctly when powered by a battery with depleted charge delivering approximately 12V or lower.
- Inline voltage regulators or switching regulators can be installed between a standard camera battery and the downconverter to step down the voltage to the required range.
- Off-the-shelf voltage regulation solutions are available from third-party manufacturers designed for this purpose.
- Blackmagic's other mini-converter models in their product line support higher voltage ranges up to 31V, but the SDI to Analog downconverter lacks this capability.
Depends on
- The discussion does not resolve which voltage regulation solution is most practical or cost-effective.
- Different Blackmagic mini-converter models have different voltage specifications, and the heavy-duty versions may have different requirements than standard models.
- The thread participants mention quality and durability concerns with Blackmagic products generally, but these remain anecdotal observations.
- Information about the specific internal power supply design of this model is limited.
