Where to buy PSU for a TEC

[Kosmos]

Where can i find a nice PSU to power a 226W TEC?

I prefer an european shop...

[antipop]

I wish i knew, if you find one tell me
I know some shops in the us that sells those but i don't know if they ship to europe

Swiftech sells a power supply for their 226w tec's. You could inquire at european sites that sell Swiftech products.

For bench PSU's big enough for your TEC.
I and recomend buying from Waters & Stanton.
Link.
The couple I & most of the TEc users have is the SEC1223 - this is ideal @25amps/13.8v for your 220W, but is £99.
Although you could try the "W-25SM Watson 13.8V Switch Mode Power Supply", I have not tried this , but its supposed to be an SEC1223 clone, and Watson do build good PSU's. Its a little cheaper at £70.
Another PSU thats good enough, and I have had chance to test is the SPS-8400 LOWE Switch Mode 40A 3-15V DC PSU still on special at £99. Towards bottom of page.

Thanks for the link, gonna check that out

NP, m8! I got a Zurich DPS-2512. 0-15v 40A PSU. Looks like the game is on for more TEC cooling.

Does anyone know if the Meanwell psu sold by swiftech (25 A) will be able to power 2x 169W tec's?

It should be able to, but you're not looking at very much headroom. The Meanwell PSU can supply 300W, you'll be drawing about 285W with both those TECs, hooked up in parallel. Should work though.

I believe the the addition of the ampage draw (current A) e.g. 10A + 10A = 20A must be less than the PSU's ampage rating.

This is if they are wired in a daisy chain i.e. series connection. If they were wired in a parallel connection (can't think of a better description) then the voltage addition is used. To power two TEC at 10v each you need a 20v supply (@ the current rating of one TEC).

You've got it backwards ;).

If you have two TECs in series, they will each get one half of the supplied voltage, if they are in parallel, they do not have to be identical, but the supply must be able to source enough current to power both the TECs at whatever voltage the supply is running at. I hope that didn't confuse anyone :D.

[megatron]

Yes I agree. In series if they are identical then the volt drop across both will be half the supply.

Having said that then the following is true. In parallel the same voltage goes to each TEC the full supply voltage, and the current to each is halved. Therefore the PSU must be rated at 40A if both TECs draw 20A at the given supply voltage.

Yep, that's right megatron.
