Understanding 12V and 24V power distribution on camera sleds and avoiding damage from incorrect voltage connections
12 years old. Gear and prices may have changed since.
What the thread found
- Most sled designs feature either dedicated 12V or 24V wiring, though some sleds have dual-voltage connectors that automatically output the correct voltage for the connected device.
- In many 24V sled systems, 12V power is simultaneously available on separate pins or through automatic regulation.
- Battery voltage typically runs higher than nominal immediately after charging, reaching approximately 17V for 12V systems and 34V for 24V systems, which can damage accessories not rated for these peak voltages.
- Damage commonly occurs when powered accessories are physically sandwiched between the sled and battery, particularly when positioned between the upper battery and sled rather than between ground and the lower battery.
- Preventing power-related failures requires verifying that all connected accessories are designed for the actual voltages being supplied and ensuring proper physical placement of components.
Depends on
- The exact connector types and pin assignments vary between different sled manufacturers and models.
- No specific testing or documentation was provided to validate the automatic voltage regulation claims made about certain sleds.
- Discussion did not address all possible failure modes or component types that might be sensitive to voltage variations.
