Selecting a 12V voltage regulator for stabilizing power from a camera rig battery to accessories
16 years old. Gear and prices may have changed since.
What the thread found
- Camera rig batteries can output 16V when fully charged and settle around 14V during use, which exceeds the 12V requirement of many accessories and causes fuse failures
- Basic 12V regulators are available commercially starting under $5 from general electronics retailers, though they have current limitations and require heat sinks
- Higher capacity 12V regulators are available in the $70 range for applications needing more robust performance
- A 1A rated regulator is adequate for devices like wireless video transmitters drawing up to 300mA
- Portable lighting equipment drawing around 3A requires a higher capacity regulator than basic models
- V-Mount battery plates with integrated 12V regulated output and dual D-Tap connectors exist as specialized solutions, though they may not be compatible with all battery types
Depends on
- Basic regulators require proper heat sink selection and may have limited current capacity depending on the specific model
- The solution must match the power requirements of the intended accessories
- Battery compatibility varies between manufacturers and may limit choice of ready-made solutions
