I just can’t get the power supply to fully power up without manually disconnecting the peltiers then plugging them back in. I’d like to check the ESR again since the overheat.

Could this be causing the problem? Are these related somehow? It could be that the soft start circuit is not ok.

You May Also Like: I also look for resistors that datasheeet darkened from heat, don’t see datasyeet in your picture. Can anyone tell me what type of SMPS this is? BTW, does the uF still gets hot, when everything is ok when you connect the peltier loads after sometime? Oct 18, 6. 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.

As soon as the peltiers are disconnected the voltage jumps to 12V and the rest of the unit powers up fans, LCD, etc In this Teardown Tuesday, we are going to take a look at the inner workings of a radar gun!

Do you already have an account? Radar Gun If you’re a speeder or sports player you may have experience with one of these! Oct 21, If the peltiers are plugged in at power up, the voltage between pins 12 and 7 is about 1.

I keep seeing alot if info regarding ripple current, but 2sc33066 ESR. I replaced the fan and reassembled the unit to see if it would power back up.

Silicon NPN Power Transistors

The fans are wired to run all the time. Switch Mode Power Supply Posted by zulkifli in forum: Same result with another 1uF cap in paralell. You can force the ic to kick up by connecting pin 4 to pin 7 darasheet but as your not getting the 12 supply to start withi would say there is an heavy load pulling the slave osc down.

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 will be similar to this design ,without the op amp chip. Oct 18, 8. It shows about 1. Yes, my password is: I also noticed that, once up and running, one of 2ec3306 heat sinked power transistors and its associated V uF input cap is getting very hot.

Dec 4, Does this make sense to anyone?

Sep 7, 2, My ESR meter operates at kHz, if I find a cap datashest a published ESR for that freq on the datasheet is that a switchmode cap or is there another key attribute I’m looking for? Oct 18, Is this a common problem with a SMPS? Dec 26, 7 0.
