Review on 💡 Efficient Monitoring of 220VAC DC12V Industrial Transformer with Supply (SMPS) by Tommy Penn

I use this adapter to power my radio. battery array and such. I have a storm and the power is out for half a day. When power was restored this power supply was drawing 50 amps while charging batteries etc. It seemed to work. an hour later I smelled burning electronics. But it still worked. Delivery stopped after 2 days. I opened it up and found that the INPUT surge suppressors (thermistors) are a white powder. They connected 2 thermistors in parallel (no spacing) for current BUT they didn't expect the extra load. (MAX DC output and MIN input (AC) means MAX input current. Larger thermistors would solve the problem.
