Great Product that does Exactly what it should
on April 8, 2013
I purchased several of these when I was installing LED RGB strip lights around the perimeter of my porch. In case you don't know, you can only run 1 string (5 meters long, about 16.5') of RGB LED strip lights from the RGB controller; for additional strings you must use a signal amplifier.
These amplifiers may take some ingenuity to mount since the terminal blocks cover the mounting slots (for the most part - 1 end is completely covered, the other about 80%), so don't count on using just a couple of screws to hold them in place. I chose to use zip ties. Fortunately I was able to drill a couple of holes above and below the amplifier and snake a zip tie through them and back out. It isn't the prettiest installation in the world but it works.
I installed 4 strings of lights. I chose to use 4 amplifiers just so all of the light levels would be the same. I could have gotten away with only 3 (powering 1 string from the RBG controller) but chose not to since the extra amplifier was not expensive.
Wiring is a snap. All terminal connections are clearly labeled. One feature that isn't mentioned in the instructions is the power wiring. There are 2 power wire connections - 1 consisting of a 5mm round plug-in connection, and the 2nd via screw terminals on the opposite side. You only need to power 1 of these - not both. I chose to use the screw terminals.
These particular units are NOT waterproof! Don't use them outdoors or where they can be subjected to excessive moisture.
After an initial goof up of getting the power wiring polarity incorrect, I got all strings working properly. About the wiring problem - you don't need to be too concerned about wiring these things backwards - they just don't work if wired improperly - you won't burn anything up by doing it, they just won't work.
All in all these are fine units. The cases are sturdy aluminum and the screw terminals work well. I've already purchased more of these for another RGB LED strip light project.
