Does this make sense to anyone? BTW, does the uF still gets hot, when everything is ok when you connect the peltier loads after sometime?

It’s also where manufacturers pinch pennies and buy cheap. The ESR of the big caps is climbing with every troubleshooting attempt. I do have a low budget scope, so I checked out pin 4.
Datasueet this be causing the problem? I just can’t get the power supply to fully power up without manually disconnecting the peltiers then plugging them back in.
Jun 22, 7, 1, Solar Powered Security Light In this teardown, we will look at the internals of a motion-activated light which contains its own solar charging datasjeet. The other parts that get stressed are the snubber R-C components, hard to pick out without a schematic.
I checked both input capacitors Datasueet and found them to be at the datasheet max limit. The peltiers are connected to the relays you mentioned via the NC contact. No, create an account now.
Oct 18, 5. Once I disconnect them the power supply comes to life.
Dec 4, Do you already have an account? Oct 18, 8. Is this a common problem with a SMPS? Oct 18, 9. Are these related somehow? Switch Mode Power Supply Posted by zulkifli in forum: It could be that the soft start circuit is not ok. Electrolytic caps are BY FAR the 1 component failure in cheap switcher power supplies because they have high peak currents rushing in and out at high frequency.
The TL usally has a slave start up oscillator oscthat produces its voltage, then the the ic takes over and feeds the start up osc with sync pulses to produce the desired regulated voltage,so your circuit 2s3c306 be similar to this design ,without the op amp chip. As soon as I get the lager caps in I’ll change them all just in case. Dodgydave – Yes, it is a 12V output supply. I disconnected the peltier coolers and everything comes to life.
I also checked the other fridge components thermoelectric peltier coolers and four datashheet using a DC bench power supply. Dec 26, 7 0. Same result with another 1uF cap in paralell. Quote of the day. As soon as the peltiers are disconnected the voltage jumps to 12V and the rest of the unit powers up fans, LCD, etc It seems to be getting worse.
The relays are energized to remove power from the peltiers as necessary for proper cooling. I figured this is what blew dstasheet power supply. Oct 18, 6.

Also, I can’t seem to find the datasheet for datasheeh caps anymore. Dstasheet, my password is: Your name or email address: I also look for resistors that are darkened from heat, don’t see any in your picture. AS to the cooking switch transistor: Can anyone tell me what type of SMPS this is? Oct 17, 3. Once the power supply is up and running, I can plug the coolers back in and the unit cools perfectly. After that I can plug the peltiers in and the unit continues to run fine and cools quite well.
Clearly didn’t know that.
