Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt to different power supplies, have longer standby power, and are safer. LEDs require a device that can convert incoming AC power to the proper DC voltage and regulate the current that flows through the LED during operation. This Switching Power Supply LED driver converts 120V 60 Hz AC power to the 12 Volt DC power required by the LEDs and protects them from line-voltage fluctuations.
Ensure your LED lights do not exceed the maximum power output of the power supply.

Really does seem to be EMI Free – That you! My big worry in any small switching power supply is EMI/RFI, as I’m a ham radio operator. When my kitchen was rebuilt a couple of years back, the contractor used a supply that looked JUST like this supply (slightly smaller by about 1/8″ in each direction) that generated noise spurs up and down the radio spectrum, and really took out the SW bandsThis supply is totally different. I replaced that “other” supply, and I can’t hear this supply, even with a SW receiver right…

Good supply for LED lighting Powering LED strip lighting with this. I bought a 15 ft reel of double-density 3528 type LEDs (600 LEDs/reel) and cut them to fit my kitchen cabinets, the whole strip draws 2.5 amps or 30W. I am running the adapter output thru a 12V pwm dimmer (aluminum case w/ 8A capacity), and at full brightness (30W) the adapter does get warm but it’s not too bad, I would not want to push the adapter over 80% of its rating though. Turn-on delay is noticeable but not too long, and the hum form the adapter…
