Electrical Circuit/Design in False Ceiling for USB-powered devices

[chaicka 195]

In the country where I reside in, we have a Power Distribution Box/Cabinet (DB) within the apartment or landed house. Generally most people will have false/partition ceiling for internal. Is there a way to run an electrical loop/circuit from the DB through the false ceiling so that it can provide USB power (5Vdc right?) to power up z-wave devices (e.g. Aeon MultiSensor 6)?

 

Is there such a product that looks like a MCB/ELCB which can be install in the DB and run cables in the false ceiling such that break-out points for usb-connector to be use to power up z-wave devices?

mcb 240v to 12v converter in the DB then use a 12v-5v adapter at the device. if you use 5v at the db, you will have voltage drop. aliexpress has everything you need.

Thanks for the suggestion and tip on voltage drop. No wonder I couldn't find any direct 240v to 5v conversion MCB.

You could also use a POE solution - cat5/6 to distribute from the main location and then small lower power adapter by the device

I use this to power my tablets around the house

That's a cool idea too. I happen to be running ES24-500W PoE switch powering UAP-AC and UAP-AC-PRO. It sure has sufficient juice to go around and power those z-wave devices.

 

Would you happen to be able to recommend a PoE to USB converter/adapter?

Hi Chaicka,

 

I use power supplies from HP (DPS-600PB). They originally were used in servers. With a bit of DIY work you will have a very strong power supply for 12V, 5V and -12V at an input from 100V upto 240V. You'll have 575 Watt power! (47 Amps at 12V, 7 Amp at +5V and 0,5 Amp at -12V)

I installed a circuit around the house with the 5V and 12V lines in it. So I have in every room my power supply for my sensors etc. But I also power my led strips with it.

 

These power supplies cost around $ 30 on eBay

On the internet there are a lot of tutorials about how to change the into a 'standard' heavy duty power supply.

I use WifiTexas ones onlu because I bought their POE unit but anything like this should work

Do a search for 5V POE Adapter and you'll find plenty

If you can get a cat cable to your locations then this might be a valid option...

Thanks for the ideas... Gonna see what is easier to implement.

Run 12VDC figure 8 cable to your sensors and use 12V-5V step down usb converters as @markdyer suggested. 12VDC supplies are readily available (DIN mount too)

Cheap and easy.

 

Can also just run 12V cable to a cupboard power point nearby and supply using a wall wart rather than running 12V into your DB.
