Hey Crankshaft, i know i came some years late but, did you tryed the DIN rail DDR-15L-5? Did it work? I tried with a Buck Converter on PCB 60 to 5 VDC but it overheats (Same system 48V battery for a 5V PI), so im looking for a more robust option, the DIN one looks nice, but i dont have suppliers for that in my country, so im looking for comments before ordering something from outside (Because i will pay like double the cost just in shipping). Hope i can get an answer over here and thank you!
