Was die Diskussion ergab

• Originale Blackmagic HDMI-zu-SDI-Mini-Wandler haben eine maximale Eingangsspannung von 12 V und werden heruntergefahren, wenn sie mit einer Spannung von über 12,5 V versorgt werden.
• Blackmagic Heavy Duty and Battery Converter versions of the HDMI-to-SDI converter accept input voltages between 12V and 31V.
• Older generation Blackmagic mini-converters are more sensitive to voltage variations than newer versions, with some units unable to tolerate voltages above 14V.
• Newer generation mini-converters of the same model have been redesigned to accept wider voltage ranges, making generation 1 and generation 2 units behave differently despite having the same model designation.
• Power from V-mount battery sleds may output unregulated voltage that can exceed 12V when the battery is fully charged, potentially damaging converters with strict voltage requirements.
• An inline voltage regulator cable (such as those with P-tap connectors or LEMO connectors) can protect sensitive converters when using unregulated power sources from battery sleds.
• AJA mini-converters and Decimator converters are generally more tolerant of higher voltages than older Blackmagic units.
• Blackmagic SDI-to-Analog converters in the Heavy Duty line have different voltage specifications than their HDMI-to-SDI counterparts, with the analog version limited to 12V input.

Hängt ab von

• Thread discusses equipment from 2011, and Blackmagic may have updated designs since then.
• Voltage sensitivity appears inconsistent across Blackmagic product line, with different models and generations having different specifications.
• No definitive method provided for safely testing a converter's voltage tolerance without risk of damage.
• Original poster did not follow up with resolution to their specific problem.
