Are these related somehow? I keep seeing alot if info regarding ripple current, but not ESR. The relays are energized to remove power from the peltiers as necessary for proper cooling. Oct 18, 6. Anything else I should look at? Oct 18, 7. It seems to be getting worse. Dataasheet May Also Like: Oct 18, 4.

I also noticed that, once up and running, one of the heat sinked power transistors and its associated V uF input cap is getting very hot. No, create an account now.

Is this a common problem with a SMPS? Oct 18, 9. Does this make sense to anyone? I just can’t get the power supply to fully power up without manually disconnecting the peltiers then plugging them back in. Ok, sorry 2sf3306 took me a few days to get this check done.

Electrolytic caps are BY FAR datsaheet 1 component failure in cheap switcher power supplies because they have high peak currents rushing in and out at high frequency. Also, I can’t seem to find satasheet datasheet for these caps anymore. Oct 18, 5. The fans are wired to run all the time.

BTW, does the uF still gets hot, when everything is ok when you connect the peltier loads after sometime? 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.

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. Once I disconnect them the power supply comes to life.

As soon as I get the lager caps in I’ll change them all just in case. In this Teardown Tuesday, we are going to take a look at the inner workings of a radar gun!

Dec 4, Could this be causing the problem? It’s also where manufacturers pinch pennies and buy cheap.

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. Same result with another 1uF cap in paralell. Output pulses on pins 8,11 feed the slave osc transistors 2sc, they self oscillate at first pulsing the transformer on the right, which feeds the 12 dc supply back to the ic on pin 12 to take over.

Can anyone tell me what type of SMPS this is? I replaced the fan and reassembled the unit to see if it would power back up. It shows about 1. The ESR of the big caps is climbing with every troubleshooting attempt. I’d like to check the ESR again since the overheat. Clearly didn’t know that.

Yes, my password is: The peltiers are connected to the relays you mentioned via the NC contact. Quote of the day. Oct 17, 1.

If the peltiers are plugged in at power up, the voltage between pins 12 and 7 is about 1.
