I replaced the fan and reassembled the unit to see if it would power back up. The voltage regulation is on pin 1 which on this design is looking at the 5v rail, yours will look at the 12v supply.

Could this be causing the problem? The other parts that get stressed are the snubber R-C components, hard to pick out without a schematic.

I disconnected the peltier coolers and everything comes to life. The ESR of the big caps is climbing with every troubleshooting attempt. Once I disconnect them the power supply comes to life. Dodgydave – Yes, it is a 12V output supply. Jun 22, 7, 1, The relays are energized to remove power from the peltiers as necessary for proper cooling.

As soon as datasyeet peltiers are disconnected the voltage jumps to 12V and the rest of the unit powers up fans, LCD, etc Not obviously bad, but certainly not good. Oct 17, 2.

In this Teardown Tuesday, we are going to take a look at the inner workings of a radar gun! Oct 21, Catasheet 18, 8. 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 2sc330 is an heavy load pulling the slave osc down. I also checked the other fridge components thermoelectric peltier coolers and four fans using a DC bench power supply.

Your name or email address: Ok, sorry it took me a few days to get this check done. Oct 18, 4. 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 dayasheet pin 12 to take over.

I do have a low budget scope, so I checked out pin 4. I also noticed that, once up and running, one of the heat sinked power transistors and its associated V uF input cap is 2dc3306 very hot.

No, create an account now.

Oct 18, 5. You May Also Like: After that I can plug the peltiers in and the unit continues to run fine and cools quite well.

Clearly didn’t know that. I keep seeing alot if info regarding ripple current, but not ESR. It could be that the soft start circuit is not ok. Quote of the day. Dataxheet 18, Does this make sense to anyone? It seems to be getting worse. As soon as I get the lager caps in I’ll change them all just in case. Is 2sd3306 a common problem with a SMPS? Oct 17, 1.

The fans are wired to run all the time. 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 figured this is what blew the power supply. Anything else I should look at? My ESR meter operates at kHz, if I find a cap with a published ESR for that freq on the datasheet is that a switchmode cap or is there another key attribute I’m looking for?

Can anyone tell me what type of SMPS this is? Radar Gun If you’re a speeder or sports player you may have experience with one of datasneet Sep 7, 2, I’d like to check the ESR again since the overheat. It’s also where manufacturers pinch pennies and buy cheap.
