Hi!
I tried to replace the PSU from my Performa 475 (TDK brand) with a RPT-60A.
I bought some connectors (JST-VH) and crimped them to the original cables, so no soldering had to be done to the Meanwell PSU.
To mount the Meanwell in the case, I 3D-printed the base by SpocksBeer (from Post #21) in PETG and screwed everything together.
But when powering it on on my workbench (without the computer attached), I only heard a loud bang and the fuse blew...
After a while, I looked inside the case, and it seems that a spark between a heatsink (HS1 on the Meanwell documentation PDF) and the metal case ignited.
I have to admint that I forgot to add insulation between the PSU and the upper case, so that might have been the problem...
(Oh, and the PSU seems to be dead now, but I've already ordered a replacement...)
My question here is: Do I have to take anything else into account before burning the next RPT-60A?
I've added a layer of duct tape and electrical tape on the cover.
I also included the connection between the outer case and the two screws M1 and M2 as noted in the documentation (
https://www.meanwell.com/Upload/PDF/RPT-60/RPT-60-SPEC.PDF )
Do I need to add something else?
Thank you very much!
Regards,
Anna
