Worked perfect for my application! It powers my 12v 3.0 amp device without issue. This is a fairly small transformer, so even though it boasts a 5.0 amp output, I have my doubts it can provide that for any length of time without some serious heat issues. In their defense, it does show a picture of the internal components with #5 being a "cooling" system that appears to be a sheet of thin aluminum for heat dissipation?
