Power Supply Plan 24 Volts 300Watt heatpad or higher : Saferhttps://hackaday.io/project/8680-power-supply-plan-24-volts-300watt-heatpad

The operation of the potential relay is based on the increase in back-electro-motive force (back-EMF) or a bucking voltage that is generated across the start winding as the motor increases in speed. The large metal mass of the motor’s rotor turning at high speeds with motor windings in close proximity has a voltage-generating effect.

AC is safer than DC. You can let go of two AC terminals but not DC as DC keeps your muscles clenched. AC doesn’t.

I’ve used 220V heaters to cook meat and I survived (quite well fed) up until now. I suppose heating a piece of plastic can’t be that much more difficult, although wh

What about putting a uC in SSRs, so you can ask the think if it’s an original part or not. Propper encryption needs to be implemented of course.

From the Auris to this, haven’t Toyota learnt anything. It’s just a slightly bigger and slightlly less DULL than the car it replaces.

Um, Though I live in Oz where we have 240 volt mains, I can see a big error in how it is explained. On, you get two different “phases” on th 110v side of things to increase the measured voltage.

My first thought was that the terminals were over torqued rotating the blocks, stretching the pins, and tearing the pads.

I was looking for a high power capable latching type to stop my old car from draining its battery… Came across this.

Which part is wrong? Lets use the IEC definitions of the different systems for clarity and you can educate me with some links to regs where I’m wrong, since I don’t do this for a living or have formal certifications in it. I’ve just a couple of years back installed 380v 3 phase into my barn conversion in mainland France myself and its most definitely a terra terra (TN) earthing system I put in. I had a inspection to get my certificate (certificate du consuel) to connect from a inspector, who during his 3 hr inspection tested the impedance to ground of my independant earth with a megga tester then checked all the earth pins in every socket for spec of impedance back to my earth point, all of which are wired star back to the main consumer unit (ring main is illegal here). We get presented 3 phase wires + a neutral as tails into our main consumer unit from the RCD device (called a disjoncteur) belonging to EDF (supply company) and its not permitted to bond neutral to your own earthing system under the regs.

We’re pleased to report that the EVF in the Sony A33 provides better dynamic range than most, and does a decent job of preserving highlight detail in high-contrast scenes. The slight distraction caused by the "rainbow" effect is relatively easy to ignore most of the time. Sony specs the EVF as having 1,440,000 dots, of which 1,152,000 are effective in the viewfinder display. We believe that the company is following precedent here, by reporting a dot count as if each pixel constituted three separate color dots, rather than being time-multiplexed. If that’s the case, the actual pixel resolution would be 480,000 total pixels, of which 384,000 are effective in the final image.
