Hi all
I'm building a LED lighting system which is controlled by an arduino (microprocessor), it will be used in a house for extended time periods (potentially 24/7) so everything will run from a mains power outlet, the LEDs and arduino run at 5V. My plan is to use the 12V 4A power supply connected to a 12V to 5V 8A regulator then to my arduino and LEDs circuit.
Using 120 LEDs x 60mA each = 7.2A at 5v total, 5v 8A power supply are uncommon so I figured a 12V 4A laptop style power brick was the best solution, a 12V to 5V 8A DC regulator will then be used to power the 5V LEDs & arduino.
My question is will this setup work? my main concern is the 12v to 5V non-isolated BUCK regulator being unsafe and giving a stable supply to the circuit.
Thanks in advanced!, I've never had to a power a project like this before and I'm just taking extra precautions to make sure its safe and reliable.
Here are the parts im look at using:
