Is my appliance compatible with the Amazon Smart Plug? | Lrd12 Overload Relay

While not quite as light as the Olympus E-420, which lacks an in-body image stabilization mechanism, the Sony Alpha SLT-A33 is certainly in the same ballpark. The A33 weighs 17.3 ounces (1.08 pounds, 492g), with battery and flash card (but no lens), while the Olympus E-420 weighs 15.7 ounces (0.98 pounds, 445g) loaded but without a lens. The lightest SLD, Sony’s NEX-5, weighs just 17.7 ounces (1.1 pounds, 502g) loaded and with its kit lens attached — just 0.4 ounces more than the A33 body without a lens.

I’m wondering why nobody is simply rectifying a 120vac input for dc wiring the secondary coil? It means you don’t have to swap the coil location or use a dc power supply. I have a trans with a secondary resistance of 82ohms. Putting 120vdc through it would be about 175watts (assuming I do a good job of determining wire size and 1.46amps is ok)

There’s a proper place for a relay and a proper place for a SSR. And I agree this solution should have been a relay.

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.

Considering the existence of deep subzero freezers, it would still perform better than a resistive element. Or have it draw the heat from the indoors and run some crypto miners to make up for it.

You now have a Tesla 3 correct? What is the efficiency hit by using 120 volts? It used to be a 30% hit for the S,X, Roadster, and new Rav4Ev with the Tesla drivetrain, Meanwhile 12 amps at 115 for a VOLT is quite efficient.

I don’t approve of that design. It lacks the third relay, which means that if you plug into two circuits on the same phase, you get 0 volts between the two hots, but both are still 120 volts away from ground. That means that the equipment doesn’t work, but it’s not safe to poke at. I prefer to insure that the 240 volt outlet is guaranteed to either be completely dead, or properly powered.

I stuck a finger in a light socket when I was about 3 years old back in Brooklyn NY and got a momentary buzz sensation. Nothing more. I got a few more 110V shocks as a US Army Air Force student of electronics back in 1944. No problems but I was warned to keep my left hand in my pocket in uncertain situations to not form a circuit through my heart, Here in Helsinki where I now live I have taken 220 V a couple of times. Nothing I’d recommend but no harm done. Nevertheless, I’m careful and never fool around with wet hands.

The Sony Alpha A33 accepts both Memory Stick Pro Duo / Pro-HG Duo, and SD / SDHC / SDXC media, and is powered by an InfoLithium battery pack.

You are right, of course. I should have used “shock” instead of “electrocution”. English is my secondary language…

“To get 120 watts at 12 volts requires thick wires that can handle 10 amps, whereas at 120V, tiny 1A wires will do”.
