This is a very nice power supply. I used it for an access control system that I recently installed and it provides plenty of power to ensure reliable operation. It is particularly helpful that they include a set screw adapter since I would not have been able to use the barrel connector. Without the set screw adapter I would have had to cut off the barrel connector and use bare leads. That would have worked but it would have made it more difficult to readily identify the polarity of the leads. I would definitely buy this item again.
