Hidden low voltage power options
4/1/2020 at 3:13:19 PM
I've got my electrical plan figured out (Simplified code book is great!) and now I'm just trying to figure out a good way to get some low voltage power available for some
smart home devices. I'm going to wall mount a couple of tablets, LED strip lighting controllers and some DIY smart devices. I'm thinking of a few way I might accomplish this.
1. Are there hard wired devices I can hide behind drywall with an access panel that'll give me a low voltage output?
2. Can I put a regular outlet behind drywall with an access panel? I have some spaces that'll be closed off with enough room. ex. Where two walls meet at a 45 angle at the back of a closet.
3. Can I run low voltage power wire behind walls to a low voltage box? Like those for HDMI cables but I would put a 12V 2.1mm plug.
I'm not thinking of doing all these things. Just trying to figure out what my options are.
Some devices will be 12V devices. Some 5V USB powered.
Any info would be great. Thanks.

There are hardwire transformer that could give you different voltage
As I recall.. You are OK to hide them behind drywall or setup a outlet inside drywall as long as you have access to it (via access panel) and they are contain and secure in utility box and etc
There are also outlet with USB which could power your USB device without additional 5v adaptor.. I am not sure on 12v..
You also likely could modify some retrofit led driver for your application.. Just as long as the driver have enough amperage at correct voltage.
There are also recessed panel that have outlet either built in or recessed from drywall so you could have full outlet usually used in home theater behind mounted TV panels
Depending on what you trying to run. You could also do low voltage wire or POE..
Just remember all wire should really be staple down inside wall.. But on retrofit project that is harder to do
