power supply

Hi,

I have to use 3 heating elements in my project. I will use AC relais and an arduino to control them.
but I was wondering if any body knows a good power supply?

I have 2 heating elements that are 500W, 240V and one that is 175W,240V

What is the power supply providing power for?

if it is for the heaters then you need a mains connection.

I’m guessing it’s to power the Arduino and AC “relays”. Look the spec of these relays and decide what voltage you need to operate them . Then decide if you can run the Arduino from that or the voltage needs reducing .
Depending on the current /voltage needed to drive these relays some form of driving circuit may be needed
