Project video:\r\n\r\nhttps://www.youtube.com/watch?v=v2L1-zPkUnc\r\n\r\nThis is my "Ultimate RD6006 Lab Power Supply". It can be powered in three distinct ways:\r\n\r\n1) A 2.1x5.5mm barrel jack, from an external DC wall adapter. 48V PoE transformers are widely used for this.\r\n\r\n2) A pair of Dewalt 20V Max batteries. This supplies approximately 40V to the RD6006, and it can output up to 1V less than that, resulting in a 0-39V output range.\r\n\r\n3) USB-C input with a boost converter. I wanted to be able to run this off a plain ordinary 5V USB source (generally using an A-C cable), so I designed the option to use a boost converter to upconvert the 5V to 14.5V, which gives a usable range of 0-13.5V on the RD6006. The boost converter causes an additional efficiency loss of at least 25% due to the necessary conversion.\r\n\r\nThe Dewalt mounts used are found at https://www.thingiverse.com/thing:3008278\r\n\r\ncase-v1, and case-v2 is intended to reduce warping as well as material consumption. Case-v2 remains untested.\r\n\r\nPrinted this in PETG without supports.
