peltier

Hi, everybody, I want to control two Peltier elements (up to 15V, max 6A each) with an Arduino. Right now, I am able to control them using PWM and a MOSFET (IRLZ44) to modulate an incoming constant voltage signal. By varying the amplitude of the PWM signal at the Peltier, I recognized, that I...

I have an adjustable power supply of 150W.I want to power two peltier modules of 12v/6amps and 12v/3amps and two fans each of 12v/0.72amps. Please suggest me an efficient way to power all devices.

Hello experts, I am working on a project which observe human interaction with robots. From my part I need to keep the robot hands at a specific temperature. Therefore, I would like to use Peltier elements with TEC controller. Is there any other idea I can go with or I should go with this one...

Hi Experts, I've got 12V, 20A, 240W SMPS (AC to DC) Power supply, & I've attached single(1) Peltier Module (TEC- 12706) - 12V, 6A(Max) with that SMPS But when I gave power to Peltier Module without Heat Sink via SMPS (Power Supply), it works for few seconds & then it stopped (Heating &...

Hello all, hope you're doing well. I have a peltier (12 V and 7 Amps) and I want to control its temperature using Arduino. I was using the N channel dual MOSFET module and it worked just fine except that it does not switch polarities. I have read about H bridges but still not sure and it is...

Hey all I'm wanting to build a water cooler like the one in this video However, I know absolutely nothing about electronics and have never done a project like this before. So I don't know if this will work as optimally as I hope and what kind of problems I might run into (hopefully none). Has...

Hello! I am trying to cool 6 Peltier tiles. They are 12v 5a. I have them sitting on top of aluminum cooling blocks connected to a dual fan 240 radiator. I am finding that the 240 radiator isn't coming close to cooling the hot side of the tiles enough. A large bucket of ice water works amazing...

I've been trying to build a small cooler using 2 stacked peltier devices, as per Youtube video. Attached is a diagram of the setup. Results have been poor at best. After several attempts, it seems the TEC-12715 module goes open circuit. (as measured on meter is diode mode) The TEC-12706...

Hi Experts, Like to know, I'm preparing a Peltier Cooler with TEC1 12706, & in same I found Cooling side started getting Hot after sometime, So is there any formula/Calculation or Circuit suggestion, which provide Constant cooling by turning ON & OFF Peltier at specific time. E.g. when I...

Hi Experts, I've SMPS (AC to DC) which gives output of 12V, 20A, 240W, & I've to attach Peltier device (TEC1 12706) with SMPS, but Confusion is Peltier have max. Current rating as 6A, but SMPS is giving 20A, So how to limit o/p of SMPS to 6A, so it wont damage Peltier, how current regulation...

My goal is to rewire a Peltier AC unit by removing the on-board PSU and Analog temperature controller. I would like to convert the AC unit to Cool and Heat by reversing the Peltier modules polarity. Then control both heating and cooling functions with a PID. Then running it all with an external...

Hello, I want to make a temperature-controlled stage for the Olympus IX73 microscope. I have attached an image of the sample holder that I need to put inside the temperature controller. Therefore I need any help with the circuit design and the circuit component. Also, I am new in the community...

Hi everyone, I've been reading many forum posts and articles about MOSFETS and reading their datasheets. Although I'm getting more comfortable with the topic, I still have a lot of questions. As I'm running out of time due to a timeline on my project, I decided to ask for help and see if what...

Hello, i am working on a project and i have 3 important questions to ask, if you can help me 1) can I use Peltier element as a heating element (because it normally works as a cooling element), if yes how please in a brief way 2) can i use O ring silicon gasket as a heating element ... i am...
