Riden RD6006 power supply case

thingiverse

Simple fairly compact case for the Riden RD6006 power supply module. This is fairly specific to my use as it uses 3x Elpac FVA100024A 24v 5A modules that I picked up for next to nothing as surplus a few years ago. There is also a 120x120x10mm fan, I used a 12v version I had on hand, but ideally, a 24v version that could be powered directly from one of the power supplies would be simpler. I used a small dc/dc converter to step down 24v to 12v. The chamber on the right is for pushing in the cord for storage vs wrapping it around the optional cord holder. The temperature sensor can be routed out the bottom through one of the square holes for monitoring battery temp etc if using this for charging. Or you could mount the sensor to one of the power supplies even though with constant airflow they should stay fairly cool. As you may have noticed 24v x 3 is over the 70v recommended voltage, I have tested it and at 72v it gives an overvoltage warning, I simply installed a 6A diode at the input to drop this slightly below 72v and it seems to work well. The diode is in the airflow path to aid cooling as it could pass 5A at maximum power (a larger diode might be a good idea) This requires soldering and mains wiring, of course only make this if you are qualified to do so. I can't be held responsible, do at your own risk. Power switch, or lack of... I may create a version with IEC inlet and/or power switch, this one I wanted to include a power cord so I didn't always have to go searching for one. The handle seems pretty strong, even though this is one of the worst orientations for 3d printing it. If you can find the Elpac modules this makes a fantastic, small, light, cheap portable power supply. Requires: 3x M4 Allen head Cap screw 10-12mm with a corresponding hole drilled/tapped or using a nut for mounting the 3 power supply modules. 2x M4 12-20mm Allen Flat head cap screw for attaching the cord wrap 4x Screw suitable for fan mounting (10-32 worked for me)
