Hi everyone. I'm working on a friend's project which controls a led array through Mean Well LDD 700H driver.
I used the LDD 700L (they have the same aspect apart from the current they support) for testing purposes while I was working on it.
A couple of days ago I went to his house to test the hole thing but it didn't work at all. I spent like 3 hours checking all my program and system looking for errors, bugs, cables disconnection, etc. However, I forgot to check one thing... my friend's driver connection. He had connected the driver backward, I mean, power input where power output and vice versa.
I've rewired the driver properly but it's still not working. My question is: Is it the driver broken or am I missing some difference between the two models?
Thanks you all.
