So far, so good

Unit seems well made, but my use is limited to a few days. Fan speed changes in direct response to number and brilliance of LED's working as they cycle.

I ordered two of these (different amp ratings) for two projects.

Original plastic terminal cover missing from one unit but company immediately shipped replacement at no charge.

TS responds quickly and gives fairly clear guidance in choosing products and hooking up.

Great product, poor documentation

Pros: this guy is quiet, provides good, consistent power, and runs cool (cooler than expected).

Cons: if you need ANY help with connections, understanding where things connect, etc, the documentation on this product sucks. Thankfully I was able to find some pics via google images of other peoples' finished products and used those as my guides.

Good power supply

I used this power supply to power 80 feet of LED Tape Light with 36 SMDs/ft., 1 Chip SMD LED 3528.
This was wired in parallel, longest run being 12 feet. Worked great

So far it has been great, no problems and very easy to work with. I did get the mounting hardware...would have been nice if it came with this.

Probably overkill but I like it

Installed this to power up my kitchen LED under cabinet installation. Probably overkill for the application but it was easy to mount under my sink on the back wall of the sink base, where I terminated LED light power leads and where I installed a 120v outlet.
