Mmh, are you sure? I know i got a package from Denver, CO weighing about the same and shipping was $30 if i remember right. Eventually USPS was the only solution, first he tried UPS but the package never left the US - apparently something about "potentially unsafe contents" - heck it was a bunch of pentium 3s, a mobo and a ton of SDRAM, i'm not sure if one could build a bomb with those.
Not sure if it affects the cost too much, but nowadays i'm living in Finland. That's still "across the pond" from you, gearheaddruid, though 🙂
Th3. how long ago was that? Less than two years ago the USPS stopped offering surface mail for international. It all goes airmail now. The best prices are "flat rate boxes" but those are still $45-$55 dollars. Weight is up to twenty pounds but the board is too long to fit in one of them. I am still going to check into it.
Recently, inverter technology has became cheap enough for everyday use. But it is generally only worth it if the application requires multiple speeds.
4KW PFC board.
Just got this today, bought the whole supply on Ebay for $30.00. The whole unit is rated at: 27 volts, 148 amps. The picture is of the pfc board. I removed the heat sinks to take the picture. The switching is done by eight W20NB50 IGBTs. They are rated 20 amps, .25 ohm on resistance, 500 volts. The toroid is much smaller than I would have expected. I will post more as I get time to mess with it. I'm going to mess with the current limiting and see what kind of power it will really do before saturation occurs.

That looks like a nice find! Good luck playing with it. 🙂
That large fan right behind it just might be a part of the explanation 😉
