As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
I bought several of these when on sale and measured their performance. Semi-Regulated would be a better description - voltage increases only modestly at light loads unlike the old-style transformer/rectifier adapters. With 123VAC input I measured 14.08V with no load, 12.9V @ 40mA, 12.5V @ 120mA, and 12.1V at 600mA. There is indeed no line regulation - the output voltage will decline in proportion to line voltage decrease below 120V. Efficiency level is V which is at least 80% under load and less than 0.3W with no load; much better than transformer-type adapters. All-in-all, ideal for driving stick-on LED tape. Just be sure the length of tape used does not exceed 0.7A.
