Is the Meanwell SE-600-24 really safe to use with the 437W TEC?

Here are sources implying that it is:

1. HardOCP's Arctic Web Review
Reviewer uses this exact PSU.
http://www.hardocp.com/article.html?art=Nzg5LDMsLGhuZXdz

2. FrozenCPU
They sell this PSU saying that it is the PSU to use with their 437W TEC module:

Now there is a thread regarding the undervolted results of this TEC:

OK, now, because wintsch labs gives conflicting information on this bad boy, theres 2 charts. I don't know which one is right, because wintsch labs is wierd. Here's the 32.8 IMax one; the second is the 25 IMax one.
437 watt / 26.7 VMax / 32.8 IMax
5 volts: 15.3 watts; 6.14 amps
6 volts: 22.1 watts; 7.37 amps
7 volts: 30.0 watts; 8.59 amps
8 volts: 39.2 watts; 9.82 amps
9 volts: 49.7 watts; 11.05 amps
10 volts: 61.3 watts; 12.28 amps
11 volts: 74.2 watts; 13.51 amps
12 volts: 88.3 watts; 14.74 amps
13 volts: 103.6 watts; 15.97 amps
14 volts: 120.2 watts; 17.19 amps
15 volts: 137.9 watts; 18.42 amps
16 volts: 156.9 watts; 19.65 amps
17 volts: 177.2 watts; 20.88 amps
18 volts: 198.6 watts; 22.11 amps
19 volts: 221.3 watts; 23.34 amps
20 volts: 245.2 watts; 24.56 amps
21 volts: 270.3 watts; 25.79 amps
22 volts: 296.7 watts; 27.02 amps
23 volts: 324.3 watts; 28.25 amps
24 volts: 353.1 watts; 29.48 amps
25 volts: 383.1 watts; 30.71 amps
26 volts: 414.4 watts; 31.94 amps

437 watt / 24 VMax / 25 IMax
5 volts: 19.0 watts; 5.2 amps
6 volts: 27.3 watts; 6.2 amps
7 volts: 37.2 watts; 7.3 amps
8 volts: 48.6 watts; 8.3 amps
9 volts: 61.5 watts; 9.4 amps
10 volts: 75.9 watts; 10.4 amps
11 volts: 91.8 watts; 11.5 amps
12 volts: 109.3 watts; 12.5 amps
13 volts: 128.2 watts; 13.5 amps
14 volts: 148.7 watts; 14.6 amps
15 volts: 170.7 watts; 15.6 amps
16 volts: 194.2 watts; 16.7 amps
17 volts: 219.3 watts; 17.7 amps
18 volts: 245.8 watts; 18.8 amps
19 volts: 273.9 watts; 19.8 amps
20 volts: 303.5 watts; 20.8 amps
21 volts: 334.6 watts; 21.9 amps
22 volts: 367.2 watts; 22.9 amps
23 volts: 401.3 watts; 24.0 amps
24 volts: 437 watts; 25 amps


I hope this chart is useful for somebody out there. If my equation for calculating these values is flawed in any way, please let me know! All of these TECs (except the 320 watt) are units sold either by dangerden or by frozenCPU and all numbers are taken from their specs.

your talking about a 437w tec running on 600w psu you can do the simple math and see that it will run no problems.

What exactly are you wanting to know?

Yes, but it depends on which numbers you use: if you use the first chart:
"24 volts: 353.1 watts; 29.48 amps"

you'll be drawing 29.48A @ 24V, which exceeds the 25A supplied by the PSU. Now if we go to FrozenCPU's website, we see that the specifications are as follows:

Imax: 32.8 Amps
Qmax: 437.2 Watts
Vmax: 26.7 Volts
Delta Tmax: 74.4 (K)
Size: 62mm X 62mm X 3.55mm

As you can see, FrozenCPU seems to say this is the "first chart version" instead of the "second chart version"... though we are unsure of their judgement.

True. But then I'd know that the PSU wouldn't work for the TEC, and I'd have to get a new one, right?

Though so many people seem to be using that one... I just don't get it. Is there something that I'm missing?

I have used a s600-24 for a 437watt tec. It did indeed work well at stock voltages, at 24 volt all was good. Anything past that and the fuse does indeed pop. But you should be undervolting such a large TEC to begin with. 19-20V~

Alright gotcha. I'll give it a try. Just for the 24V'er. The 13.8V one is still in the works.

be careful with the numbers from my chart; assuming TEC resistance remains constant with changes in voltage (plausibly unlikely), the power draw figures are right, but if it does change, then all bets are off :)

Yea I understand... and resistance is obviously a partial function of temperature. Though if there are two relatively major sources saying that it is alright, then it might be a good bet, right?

Though by the same token, FrozenCPU might not understand all of the implications and such... though I think betting with HardOcp & FrozenCPU might be a good bet.

I personally use the -15 volt flavor to allow for a wider rage of voltages. I can run all the way from 12 up to around 19-20V if need be. Currently I'm running at 14V and love it. If you need some help deciding let me know.

Oh, and the -15 has more amps on its line than the 24 does.

Interesting; I guess I should check what range of voltages are available for the 24V version. I'd like to read up on the -15 version also. Though getting rid of the heat isn't what I'm afraid of at all. I've no doubt I'll be able to do it.


EDIT: I found this on ebay:

It is the PSP-600-15. I have this weird suspicion that it is what you are referring to. Though its quite funny who they're both 600W exactly. Dang, I wish there were a PSU just a tad bit over 600W... say 624W to allow for another amp.

Duh

Current sharing up to 2400W(3+1)

How about that? I do not really get it. Are the able by any means to be connected in parallel series or anything similar?

If your running the PSU right on the limit remember to keep it coolish.
If it seems like its getting very hot put another fan on it. Running a PSU at the amp limit and letting it get hot is asking for extra trouble. At 100% load it should be no hotter than 40*c (from the PDF)

The amps drawn by a TEC will alter somewhat with the temperature differential across the TEC.

So... briefly.. the colder you can get the waterblock side the more amps.
And the hotter the CPU side the less amps. And vice-versa obviously

But unless your doing some thing odd (like cooling low wattage CPU at a high DT) you shouldnt be able to get too far from the charts wattages using a "normal" CPU and "normal" cooling.

Im not sure if you can run these PSU in paralell or series, as im not sure what
2400W(3+1) the 3+1 part means.

Anybody know what the "RS" connector is for ?

I see... hmmm I suppose maybe I should take an ammeter and measure the current and see just how much I'm actually drawing...

HEY!!!

That would be an excellent addition to this forum!

I see; then that would make sense now. I see that 4 * 600W is 2400W, so the figures do match up. I know some Meanwell PSU's may be connected in parallel. I suppose this is then one of them.

As I have said many times before, dont trust what you read in ebay adverts 100%.

I would email meanwell and ask them if it will work.

If running in series make sure that the - line isnt also earth (as it is on some PC PSU's) or the PSU will go bang! (shorting on the case of the second PSU)

In paralell the voltages need to be the same or odd things might happen to the PSUs ..

Ive never used a meanwell so I cant say for sure, but it should be easyish to find out.

I have read from the specs that at least some of them can be hooked up in parallel, as I remember.
