Change power cord to the Ultra

[dtc]

I was about to post that this is the craziest thread on this forum I have seen to date then I thought hang on, maybe it’s to do with the crap household electricity system that they have in the US compared to the European and UK systems. In the US you have 2 pins +/- no earth whereas we have 3 pins - +/- and earth.

I might accept that a power supply can influence SQ but not the basic cable ahead of the power supply. That’s crazy.

US homes have had 3 wire plugs with ground/earth for many years - decades. Some electronics (like phone chargers and other devices that use DC current) are not grounded but the electrical system including outlets in a house is definitely grounded.

Same as in Europe.

You're just using the wrong voltage. And mains frequency.

At least they haven't redefined Volts and Hertz

Sounds like a great name for a German heavy metal band

Of course, in building the first power plant at Niagara Falls, Telsa used 60 Hz since it is 20% more efficient than 50 Hz. And, of course, without Edison's light bulb, Europe would still be in the dark.

Joseph Swan would have a different opinion

Edison wasn’t first to invent the light bulb but first to market

Americans still seem to be under the illusion that Edison invented the lightbulb.

No, Edison and Swan did so pretty much at the same time. Both men actually patented their light bulbs in the same year - 1880. Edison just made it practical. That is why Swan joined with Edison to form Ediswan, which is what lighted London.

Is there really any efficiency advantage to be had in the mains frequency? I don't think so. There definitely is an advantage in the higher voltage.

But I don't really want to argue. At least we all agree that Edison's DC concept was inferior (despite of all his trickery) and didn't make it in the end.

Right now there are probably far too many appliances to ever expect a harmonisation of the main frequency.

Is this the thread you intended to post to?

I don't see no power, no cord nor the WiiM Ultra.

You can use smaller transformers at 60Hz.

I don't have to.

And how would a transformer be able to change the mains frequency from 60 Hz to 50 Hz?

Eh?

 

[harkpabst]

Eh?

Go ahead.

A transformer can transform voltage. It cannot transform the mains frequency. No way.

Who said anything about changing the frequency? A 60Hz transformer can be smaller than a 50Hz transformer.

Yea i dont care
