Lenovo’s latest Yoga laptop has an ARM processor and 25 hours of battery life | 220v Contactor Relay

Still, the orderly May backdrop registers as bullish, versus the prior three months, punctuated by the S&P 500’s flag pattern pinned to the steep early-month rally.

The U.S. benchmarks are approaching the unofficial start to summer amid characteristically range-bound, and slightly sluggish, price action.

You have right, a isolated SMPS is used. The Microchip solution presented above will not work properly because of the ESP Module power requirements.

I can see exploding TRIACs happening more often on cheap dimmers and such due to under-rating the load and little to no heat sink.

Flake has said he won’t back any judicial nominees until he sees a floor vote on legislation that protects special counsel Robert Mueller and his investigation into Russian election interference.

For the person who jumps up and says “coatings insulate the water from the trace”, well no it doesn’t, we are talking about AC voltages and water that has formed over a large trace (even insulated) forms a capacitor that will conduct AC even when you have a DC insulation. Even if it did you then still have the exposed solder pads.

many years ago I had the bad behaviour to strip cables using my teeth… well, one day I was ready to strip the end of a cable that used to connected to my portable stereo (240v), its just few seconds that I noticed that the other end was still plugged-in on the mains…

If he ever turns his car on its side so that the car jack is pointed toward ceiling and plugged into the evse as shown, then I’d worry about it.

I work with high voltage all day everyday except for weekends, and then I’m probably doing some wiring or something at my house. 480VAC is on the low end of the voltage scale for what I do. The biggest and most important safety tip is: “Know thy equipment.”. That means knowing where the 480VAC is coming in, everything it powers, where that voltage gets stepped up to thousands of volts, what chassis and assemblies are floating at high voltage, at what point of the turn on sequence they are at high voltage, knowing what to use a chicken stick on when things are powered down (i.e. the high voltage bits – BUT NEVER AC MAINS!!!). I’ve seen the ends of chicken sticks where the unknowing tried to short 480VAC to ground… thank el diablo for fast acting circuit breakers… If you do not know what the hell you are doing or think suiting up in some silly bomb suit and silly gloves that are going to get you killed faster with than without, you need to stay the hell away from anything over 28 volts…. You cannot troubleshoot everything with LOTO, you sure as hell can’t troubleshoot with big stupid gloves and a bomb suit on. Those things were invented by desk jockeys who have never had to work on anything themselves in their lives. Great for theory, terrible for getting shit done. Knowledge is the only thing that will keep you safe. Stupidity and trusting others to keep you safe will kill you.

Although we bumped into each other on job sites, we had different employers. I knew his family and I wasn’t about to ask them about the details of course.

But this time, as I tested the 2018 Kia Niro PHEV, everything went right. I was able to drive and charge this plug-in hybrid like a normal person who has to keep it for more than a week. Full charges greeted me each morning. And, at the end of my test, some seriously impressive fuel economy blew my mind.

Bottom line, while the Sony A33′s EVF doesn’t entirely conquer the challenges of its genre, it goes further in the right direction than any other I’ve experienced to date. Most telling is that I now find myself reluctant to give up its benefits and return to world of purely optical viewfinders once again.
