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 tried to use this controller, but apparently I did something wrong. I followed the online pdf file and even switched the white/black AC lines My green wire is ground and according to the directions is used as one of the AC inputs?! However, I do not see a variation in AC voltage or current output irrespective of the wiring what is supposed to change as the pot is changed?. I would greatly appreciate if the first reviewer JAD, FL send me a copy of his wiring diagram my email is firstname.lastname@example.org!!
Operable with caution
Basic triac control, as above no rfi suppression and at 120 volts heat sink undersized for anywhere near 8 amps. Wiring diagram not for any USA electrical code, if used will break neutral while leaving line always hot. Simple fix, just reverse leads. No ground terminal. Heatsink is NOT live to either line or neutral as triac has internal insulated ceramic pad isolator. Having noted that would not allow sink to contact any metal case you may put it in, in case of catastrophic failure. Terminals sized for know known USA approved line cords. Use caution. However, was able to mount in standard enclosed outlet box with ground and add 3 pole plug and socket. Works well on my HF 5 amp grinder on gfci protected line.

With some adjustment, working fine on Dremel. How can I test for the RF this is said to emit? Can I find it on a radio? Yeh, you Barry! Ive neighbors Id love to pester. Can it be optimized for RF?

Not 2 Kw. Underpowered.. but works if you keep it 8A or less.
Lets start with the simple math: It says the dimmer is for 220VAC 8A maximum. That is only 1760 watts, not 2000. At 120VAC 8A, it will do less than 1000W.. so, forget using it with your big router, circular saw or 2 500W quartz lamps. Compare your requirements with its capabilities before purchasing.
Also, they mention that it has no filtering. It will put out a lot of hash switching noise on the power line. As always, keep your AC wiring far away from microphone or sensor cables, as well as logic-level signals. And be ready with a good story if your neighbors call.
