hi, im working on a project. which is unit for cell culturing process. I need to connect the microcontroller used to control the uv light and user interface with main powers.
how can I do this?/
thank you

 

Isolated power supply, look at any small SMPS such as the Wall Wart plug-in to any socket outlet. Do you just need 5vdc?
Where are you located?
Max.

 

hi MH,
Welcome to AAC.
Do you have a block diagram of the project, showing how you would see it interconnected.?
E

 

Hi max,
as I mentioned earlier, we are designing a unit where 3d culturing can take place. so we need to control the temperature, humidity and uv light to cure the cell. we are using Arduino uno to control everything. but I need to know how can I connect all the system to the main power supply in the world.
thank you so much for your help

 

I assume 'the World' means your local power service provider?
What are the operating of the systems apart from the micro and the power demands?
Max.

If I understand you correctly, all you need to do is acquire a few ssr's to switch your devices on and off using the mcu of your choice.

 

hi cmartinez,
yes that's what I want.

Makes sense, if this is the object, I didn't quite get the question!

hi max,
there is a chip that goes out and in to put the cell on it.
yes my local power supply (uk)

 

hi cmartinez,

Well, there you go. They're inexpensive, and extremely simple to use. Let us know if you have any questions on how to connect them.

 

For any smaller DC load current versions you may require, an opto on the Micro to drive a 2n7000 or other logic gate Mosfet may work. Also the opto could drive a Triac.
Also the micro will drive a logic Mosfet directly if isolation is not required for a particular load.
Max.

 

should I use smps also?

 

They are about the most economical, but not always the most rugged, (or fixable).
Max.

 

so ssr and smps do the same thing ?

 

Hello,

A SSR is a solid state relays.
A SMPS is a switched mode power supply.

Yeah, a triac can be the cheapest option. And replacing them can be easier if they're mounted on the PCB using ordinary screw terminal blocks.

yeah I know, but do they have the same function

 

Hello,

No, they do not have the same function.
The SSR is a relays to control a device.
The SMPS is a to provide power to a device.

yeah I know, but do they have the same function

Completely different function, a SMPS is a Switch Mode Power Supply AC to L.V. DC usually.
A SSR is a solid state switch.

Are you citing the Opto22 modules?
They are nice, but limited in current rating, also if using them as a replaceable module you need to either use one of the Opto22 distribution boards or custom make the receptacle on a PCT board, which I have actually done in one case.
Also available with 5vdc input.
Max.
