It calls out a MOC3041M on the silkscreening. One can use a MOC3041 of course as they are the same form factor.
I can’t speak for the ‘3’, but you can – since you can at least compare your cost of charging with the 240 – 250 volt cost in the Tesla Calculator.
However, DC distribution at the municipality level and smaller will be a nightmare to make work. Pretty much *everything* needs to be replaced, and for what purpose? It doesn’t really solve any significant problems and raises a host of others.
[Nick Sayer] falls into the “would rather build it than buy it” category. This particular project is a clone of a fast electric vehicle charger. There are commercially available versions sold under the Quick 220 brand name. The idea is that for fast charging, some electric vehicles call for a 240V outlet and Americans without electric cars often don’t have one. If they do it’s for an appliance like a stove or clothes dryer and probably not found in the garage.
It’s just sensible to avoid risks where you can. If it doesn’t cost much extra, why not bother? Tinkering with a 3D printer is likely to take concentration away from other areas. Low voltage is intrinsically safe from electrocution. Don’t make things dangerous for yourself.
Did you keep records so that you actually know you repaired 15,000 TVs? I don’t believe it, and if it is not true then I doubt your other statements on this evidence alone. People should classify their statements as to fact, fiction, or opinion, not just leave them in an ambiguous interpretive limbo.
The basic concept of your point is looney. Voltage doesn’t cause heat, The only thing heat dependent for a given installation is the current – of which 120 volt charging is usually less than 240.
I forgot to say that 220 volt AC is effectively 310 volts peak, so therefor one could instead use 300 volts DC instead, giving roughly 25% less current to carry in the wires to get the same power in the end.
Yeah, dont use these. Use a relay instead. There is a reason all the high end stuff went away from the Triacs as they will float to full mains voltage when no load is connected and you get electrocuted when you mess with the circuit. AMX, Crestron, Lutron, etc all have moved away from pure Triac control due to this safety issue.
The Mode dial on the left shoulder is used to select the camera’s operating mode. An angled panel allows you to view four buttons from either the rear or above: Menu, Movie, Exposure Compensation, and Auto-exposure Lock buttons.
Everything industrial is 3 phase though; it’s 240V phase/neutral or 415V phase/phase here though. You can certainly get a 3 phase connection to your house and/or shed though – it costs about $1000 to replace the meter plus a bit more for wiring – if you have a problematic power-tool habit like me.
A blocked or dirty air condenser can also degrade the performance of your unit. Make sure the vents around your air conditioner are clear of debris and the area surrounding your A/C unit provides plenty of air flow.

We thinks what clients think, the urgency of urgency to act from the interests of a purchaser position of principle, allowing for greater top quality, decrease processing costs, price ranges are much more reasonable, won the new and aged prospects the support and affirmation for 220v Ac Contactor , Electric Contactor , High Quality Circuit Breaker , Now, with the development of internet, and the trend of internationalization, we have decided to extend business to overseas market. With the propose of bringing more profits to oversea customers by providing directly abroad. So we have changed our mind, from home to abroad, hope to give our customers more profit, and looking forward to more chance to make business.
