Review on ⚡️ 250W Intelligent DC DC PSU Power Supply Unit M4-ATX-HV with 6-34V Input by Stephen Russian

I was really hoping that this product would solve the problem with the medical device I was developing. It is used to help very sick people in third world countries. There is one very important feature that should work with this PSU, but it doesn't. I understand that nothing is perfect so I tried to contact tech support but they refuse to answer me. It's been 5 days. We planned to buy 2000 of these per year. At the moment we are looking for another product.
