Wireless accessory failure when using high-voltage battery setup with film camera
16 years old. Gear and prices may have changed since.
What the thread found
- A camera rated to accept up to 35 volts should handle input voltage in the 32-volt range without direct damage, as cameras typically have regulated power supplies for both input and accessory output.
- Voltage differences between DC ground and video ground connections on the sled or accessories can damage sensitive devices when connected together, even if individual components are not overpowered.
- Ground continuity problems should be diagnosed using a multimeter to measure voltage between different ground points on the sled, camera, and accessories both with power on and off.
Depends on
- The specific cause of the wireless sender failure was never definitively established in the discussion.
- The suggestion about ground issues was theoretical and not confirmed to be the actual problem in this case.
- No testing or measurements were actually performed to verify the theory.
