Will no one help me?
Hi all, as above, I have a unit with model no MC-789. Unfortunately the power supply broke down and there's no spare parts available in market. Hoping to have some experts here could help if there's any other standard power supply i can get from store. Thanks.
Will no one help me?
Is there anyone out there could help me out?
Do you know what is the power your PSU is supplying? If you do, you could try and get a spare one of equal or more power rating and replace (at hardware or 2nd-hand electronic shops). It should work.![]()
I see... ok just realised it is a peltier-based cooler... are you certain its the power supply that broke down? what made you come to the conclusion e.g fans not moving? cooler not cooling water?
Once upon a time....just kidding. One day came back from work, it totally stop working. Discovered that the fuse blown, got it changed and blow again right after switch on. I itchy hand, open up the power supply and found there's a green capacitor cracked and a transformer slightly melted.
Later went to the electronic supply shop got the parts (not sure if it's with correct spec), replaced it but still blow my fuse. Now, I'm left with a big question mark....

hmm... for a small peltier cooler, it will most likely not consume more that 100-150w power. I suggest you change your psu entirely to a new or second hand(even computer psu can work) of about 200w. Peltiers will not draw more power than it can consume so assuming it is a 80w cooler , there should be no problems 'overpowering' it with a stronger psu because your psu will only supply 80w... but there is a possiblilty of running your cooler at maximum setting and burning it out or overheating..best is if you can find out what is the power rating of your cooler.. the problem with this solution is you will have an external psu unless you can fit it into your cooler...

Looks like you are the someone which could really help me. Ya, close to your estimation, my TEM consumes 150W. It's written outside the unit's cover. Sure computer psu would work? Because i have an old cpu lying around my house. Say some 10 year old cpu. Think suitable? By the way, it combines 2 TEM units into 1 with 2 fans. Original design comes with seperate supply for each TEM. If use computer psu, can power it together from that 1 psu?
And about the external psu, it also originally comes that way. Maybe i post some pics for you to see tomorrow (If I KO early).
You're in Malaysia? If you visit Singapore, you can actually just bring the whole thing down to Continental Electronics in Sim Lim Tower Basement, and show to the uncle.
They can repair for you, or advise you what you need to do. I've not seen the inside of the Dolphin ones, but I have used PC power supples to power a peltier before.
yes computer psu can work provided you know how to use it. e.g you would have to short the psu and connect the TEM properly..
infact there is an article in shrimpnow.com which details the process of building a TEC cooler and it shows how to connect to a psu..
since you said there is seperate psu for your supply, it might get more tricky as your 10 year old psu might not be able to support 150w with one cable.. i am assuming you mean your TEC consume 150w in total? and not individually? otherwise your old psu will probably not support it..![]()
Hm...sounds like I'll have an interesting experiment to be carried out soon. Whether the 150W in total, I'm not too sure,but I think so as usually the indications stated are meant for the unit as a whole, agree? I'll 'operate' my 'old friend' soon and see if i can find the specs an the psu
. Just to clarify bro deon, do you mean that as long as the psu is ranged from 150W - 200W, it should be able to power up the unit as a whole without damaging it?
don't use a cheapskate power supply. Those included with casings, brandless or china brand PSUs will probably explode within 3 months.
Get a reputable brand one, and get one at least in the 300w - 400w range to be safe.
FSP, Enermax, OCZ, Seasonic are all good brands, but carry a premium pricing.
Failing which, Antec, Amacroix, Coolermaster also can.
Did some investigation around today and seems like no need of shorting the psu. I was told if i would just take 2 4 pin connectors from the psu, cut the yellow and black line and connect it to TEM, that should work. Concerning the link which do teach of proper way, mind sending me the link?
i believe you can find it here, http://www.shrimpnow.com/viewarticle.php?articleid=37
are you planning to connect both TEC to one psu? If you are better get a new and more power PSU...
Bro, according to silane, there's also 24V TEM. As computer psu only supplies 12V, I'm afraid it wont work. Need to check and confirm first before i waste my money buying psu and ended up not usable. Ya, if i really buy, I'm planning to get about 400W unit. Amp vice, I'm not really sure. But my blown fuse was 4A. I've also pm silane for advice, hope he could guide me.
don't worry your TEC is probably not 24v... my peltiers (huge) takes in max 15.6v and 30Amp.. so a small TEC such as your chiller's would only take like 12v-ish(likely less) and 6A-ish...
anyways even if your TEC are rated at 24v, it can still consume only 12v depending on how much power your PSU can supply..
Suggest you get a nigher rated fuse..
Hm...with your words...I'm quite convinced that my problem is solved. Thanks bro deon! you've really been a great help. Really appreciate it. Now I'm trying for another round to replace the broken component on the original board. If still same, I'll get a psu to power it up. But please do keep track as i may need more help if it still doesn't work. Thanks again...
No problem...
i suggest you use your old PSU to test out before buying a new one because your peltiers or other components might be spoilt, in which case replacing it would not be cost effective...![]()
