Riden RD6006 power supply case

thingiverse

Here is a compact case designed specifically for the Riden RD6006 power supply module. This project utilizes three Elpac FVA100024A 24v 5A modules, which I acquired at a bargain price several years ago as surplus items. Additionally, this design incorporates a 120x120x10mm fan; ideally, a 24v version that can be powered directly from one of the power supplies would be simpler to implement. To overcome this challenge, I employed a small dc/dc converter to step down the 24v voltage to 12v. The chamber on the right is designed for storing the cord by pushing it in, as opposed to wrapping it around the optional cord holder. The temperature sensor can be routed out through one of the square holes at the bottom for monitoring battery temperature or charging purposes, if this device is used for charging. Alternatively, you could mount the sensor directly onto one of the power supplies; however, given the constant airflow, they should remain relatively cool. As you may have noticed, 24v x 3 exceeds the recommended voltage of 70v. I've conducted tests and discovered that at 72v it triggers an overvoltage warning. To rectify this issue, I installed a 6A diode at the input to drop the voltage slightly below 72v, and it appears to function well. The diode is positioned in the airflow path to aid cooling, as it could potentially pass 5A at maximum power; a larger diode might be an even better choice. Please note that this project requires soldering and mains wiring, so only proceed if you are qualified to do so. I disclaim any responsibility, and you should perform this task at your own risk. This design does not include a power switch, but I may create a future version with an IEC inlet and/or power switch. For now, I've included a power cord to avoid having to constantly search for one. The handle appears to be quite robust, despite being printed in a less-than-ideal orientation. If you can find the Elpac modules, this makes for an excellent, small, light, and affordable portable power supply. Required components include: * 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).
