It shows about 1. Solar Powered Security Light In this teardown, we will look 2cs3306 the internals of a motion-activated light which contains its own solar charging system. I also look for resistors that are darkened from heat, don’t see any in your picture. I checked both input capacitors ESR and found them to be at the datasheet max limit. It could be that the soft start datashee is not ok. Can anyone tell me what type of SMPS this is?
Quote of the day. It seems to be getting worse. Radar Gun If you’re a speeder or sports player you may have experience with one of these! Dec 4, The TL usally has a slave start up oscillator oscthat produces its voltage, then the the ic takes over and dtasheet 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. Switch Mode Power Supply Posted by zulkifli in forum: Oct 21, Oct 18, 7.
Oct 18, Could this be causing the problem? The voltage regulation is on pin 1 which on this design is looking at the 5v rail, yours will look at the 12v supply. As soon as the peltiers are disconnected the voltage jumps to 12V and the rest of the unit powers up fans, LCD, etc Anything else I should look at?
Oct 18, 8. Oct 18, 4. Also, I can’t seem to find the datasheet for these caps anymore. The relays are energized to remove power from the peltiers as necessary for proper cooling.
Once I disconnect them the power supply comes to life. Your name or email address: Are these related somehow? I’d like 2sc336 check the ESR again since the overheat. Once the power supply is up and running, I can plug the coolers back in and the unit cools perfectly.
Dec 26, 7 0. Usually with this type of psu, there will be a delay to get the 12v up working, then it will 2sx3306 the peltiers, there must be a slave smpu on the board to give the ic its 12v.
Oct 17, 2. 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 eatasheet ic on pin 12 to take over.

The ESR of the big caps is climbing with every troubleshooting attempt. I just can’t get the power supply to fully power up without manually disconnecting the peltiers then plugging them back in.
Does this make sense to anyone? No, create an account now.

Sep 7, 2, I disconnected the peltier coolers and everything comes to life. 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. I replaced the fan and reassembled the unit to see if it would power back up.
The peltiers are connected to the relays you mentioned via the NC contact.

I figured this is what blew the power supply. Clearly didn’t know that. Oct 18, 6. You May Also Like: Not obviously bad, but certainly not good.

Ok, sorry it took me a few days to get this check done. Oct 17, 3. The fans are wired to run all the time. 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. Yes, my password is:
