I purchased this from Amazon and it arrived the other day. I plugged it in (properly) and it melted my leads. I investigated further and found their was a dead short on the power terminals. I considered reordering but this didn’t leave me with a lot of confidence in your product. I was wondering what you could do to correct this issue. Doug Clark
To check what wrong it is, would you like to show us the connection or other operation details? For example, did you connect input power only in that time?
