First off, why this supply uses a very thick wire for the 120V side is beyond me. It is very large in diameter, about 0.275", and very stiff. The wire gauge is needlessly large. 30 watts of reflected power at the primary is only around 0.4 amps of AC current, which is very small. Therefore, the first thing I did was cut off this cord close to the input of the power supply and splice in the male lead of a 16 gauge extension cord, which is much thinner and more flexible than this ugly black cord. I did not connect the green safety lead because as far as I could tell, it connected to nothing, including the aluminum chassis. I poked through the case's non-conductive anodization with my meter probe and tested for a connection to this green line. Nothing. Nada. So I left the green lead floating. (For those of you who are safety-crazy: look at all of Apple's power supplies. 2 leads.)
Next, the output. Here again we have a needlessly thick, yet short length of wire. For an electronics guy like me, it's no bother. But what's a guy who doesn't know how to solder supposed to do with it? There is certainly an assumption on this power supply that you, the purchaser know how to solder. I clipped this cord close to the chassis and then spliced in an 18 gauge lamp cord, taking note of which lead is positive (red) and which side is negative (black).Read more ›
UPDATE: I have found and fixed the cause of the humming/buzzing. It was the dimmer's fault. By putting 2 16v 1000uf capacitors across the input of the dimmer, I was able to reduce the buzzing by 99%. I'm sure the correct value of capacitor will fix it 100%.
I contacted the seller and they offered a refund, but I thought I would test this out with an electrial engineer at work. We wired it up and tested it up to 5.0 amps and it worked very well. I've decided to keep the unit since it will handle the load nicely, but you should be aware that you might recieve something different than what the seller describes.
well, I no longer like this power supply. For the past couple weeks its been flashing on and off randomly. It only does it after being on for an hour or so... it will shut off for a second and then come back on. Sometimes it will just flash rapidly for 10-30 seconds. I've checked my wires and everything seems OK with the wires. It must be the transformer.
This thing lasted long enough that it can't be exchanged... but it failed so soon it only gets one star now.
Now its time to look for a better power supply. Maybe its time to hack a laptop power supply and use that? Time will tell what I figure out.
Be advised before you buy, it might just fail after 2 months of use.
ORIGINAL REVIEW: 4 STARS
I installed this with LED undercabinet lighting.Flexible Light Strip 300 SMD Bright White LED Ribbon 5 Meter or 16 Feet By Ledwholesalers, 2026wh
I wired it with a switch on the wall, leading to an outlet inside one of my cabinets. I then mounted this power supply in the cabinet and ran the low voltage wire up into the ceiling and around to all the cabinets. I used some washers to space this out away from the cabinet wall about a quarter inch. I'm not sure how warm this gets when it is on... but I figure having some air space would help keep it cool.
Install was easy enough (I did it before the counters went in). I soldered the wires to the output wire of the power supply. Now that I've thought about it more... I should have used some quick-connect wire fittings to connect the power supply to the low voltage wires.Read more ›

Works as described, only issue I have with it is that the manufacturers need to find a way to dissipate the heat better as this is a potential hazard.Published 16 hours ago by Landael Willins
