RF transmitted power Legality / Codes.
I'd like to create a power source that could energize a small LED circuit at a maximum distance of ~3 meters. Even better, build an adaptive control, ensuring additional circuits are adequately powered, but design-limited to a safety max.
My concern is to ensure the power source conforms to applicable United States regulations / codes. I have a background in physics, but no experience in electrical engineering or contracting. So I really don't know where to begin translating theory into device. Can anyone suggest advice / guidance / starting references :
- What is the legality in the United states?
- Are there any codes that apply / regulate transmitted power?
- Pro tips?
