I do have a low budget scope, so I checked out pin 4. Are these related somehow?

Yes, my password is: Same result with another 1uF cap in paralell. The fans are wired to run all the time. Oct 18, 9. Oct 21, The dataseet are energized to remove power from daatsheet peltiers as necessary for proper cooling. I checked both input capacitors ESR and found them to be at the datasheet max limit.

I found one fan that was drawing much more than its rated current and not turning.

Oct 17, 2. Oct 18, 7. Clearly didn’t know that. Dodgydave – Yes, it is a 12V output supply. Oct 18, The other parts that get stressed are the snubber R-C components, hard to pick out without a schematic. I just can’t get the power supply to fully power up without manually datashet the peltiers then plugging them back in.

2SC (Mospec) – Power Transistors(10a,v,w), NPN

I keep seeing alot if info regarding ripple current, but not ESR. I disconnected the peltier coolers and everything comes to life. Dataxheet 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 will be similar to this design ,without the op amp chip.

The ESR of the big caps is climbing with every troubleshooting attempt. Solar Powered Security Light In this teardown, we will look at the internals of a motion-activated light which contains its own solar charging system.

I also checked the other fridge components thermoelectric peltier coolers and four fans using a DC bench power supply. Quote of the day. Usually with this type of psu, there will be a delay to get the 12v up working, then it will power the peltiers, there must be a slave smpu on the board to give the ic its 12v. My ESR meter operates at kHz, if I find a cap with a published ESR for that datasheer on the datasheet is that a switchmode cap or is there another key attribute I’m looking for?

You can force the ic to kick up by connecting pin 4 to pin 7 ground but as your not getting the 12 supply to start withi would say there is an heavy load pulling the slave osc down.

No, create an account now. Do you already have an account? BTW, does the uF still gets hot, when everything is ok when you connect the peltier loads after sometime? I replaced the fan and reassembled the unit to see if it would power back up.

Once the power supply is up and running, I can plug the coolers back in and the unit cools perfectly. The peltiers are connected to the relays you mentioned via dafasheet NC contact.

Sep 7, 2, Jun 22, 7, 1, Does this make sense to anyone? As soon as I get the 2sc33006 caps in I’ll change them all just in case. Oct 18, 8. After that I can plug the peltiers in and the unit continues to run fine and cools quite well.
