Greetings,
I am experimenting with a Switch Mode Power Supply, a rather cheap one actually, and I have found that the Common Mode Choke / inductor Filter may be running too hot. It is a 60v 10Amp unit.
With a laser thermometer I measured 237F at the coils.
This is when running the PSU at 5Amps. I didn't dare run it at the full 10Amps due to the possibility of releasing the magic smoke.
In the image below you can see the PSU in question and the Common Mode Choke circled in red. It seems too small for the application.
I was running a 48v inverter with it and had a 5Amp load attached to the inverter.
How difficult is it to calculate the correct choke for this application? I do realize that sending it back is easier, but I am trying to learn electronics and this is a challenge.
Thanks in advance.
