I bought 2 trusted brand LED drivers. They are LPC-20-700. Spec says it's constant current 700mA, but I blew my whole project. After (yes, I know) that I tested the driver and while it gives me the correct voltage 30V, the current is 1.1A, which is 400mA more.
I have a hard time believing the drivers are bad, because I've read that this is a safe brand. I bought good ones to avoid house fires and such.
Is there any possibility that I'm doing something wrong? It seems very simple but the results are wrong.
