Hi,
I'm actually working on a boiler controller. Alimentation is 240VAC. I use an onboard power supply to get a low DC voltage to drive a microcontroller. This controller drive a relay to drive a heater.
My controller has to pass the CSA norm.
I've been told that the isolation voltage between AC and control DC has to be 1.5kV and I that I should test it. They talk about it in therad thread97524...
I don't understand what is the utility of this test except passing the CSA norm... Someone know?
Thanks !!
