Going to enclose a meanwell lrs 150 series supply and add a fused power entry module with switch along with a few banana posts. Is there an ideal enclosure for this? Currently only junction boxes seem ideal for this. |
| ArthurDent:
What I have done for enclosures is go to hamfests and look for some useless piece of commercially made equipment in a really nice case. There is generally a good collection of stuff people are willing to dump for just a few dollars. After I gut the thing, I generally end up with a IEC power connector/filter, switch, and fuse on the back panel ready to be used with what I build inside. Make a new front panel and I'm ready to go with a nice professional looking enclosure |

Depending on if it needs to be dust or moisture proof I have done a few of these for Meanwell and similar supplies for IEC sockets and cable control. If you can find the or draw the correct one up then get it printed by a service or a friend if you don't own a printer. Other than that I am a fan of retasking old gear too generally they don't cost much if you can wait for the right bit of obsolete gear to come up on evilbay or your local junk shop. |

I'm trying to use a 3d printer for this. I expect the result to be awesome, but there are two limitations: 1) the enclosure is gonna be plastic, no metal. So, if shielding is needed, it has to be done somehow else than relying on the enclosure itself. I heard there are EMI sprays, but never tried myself. 2) they don't like high temperature. Where "high" can as low as 50C for PLA, a bit higher for PETG and ABS. So, check specification or do an experimen to be sure it's not going to melt or soften too much. |
| beanflying:
PETG is easier to manage than ABS and its tendency to crack or curl off the bed and it goes close to ABS for Temperature. PLA is fine as you say to around 50 with good stability and depending on the job/design then post heat treating gets some much better results by changing the Crystal structure. There is plenty of fully enclosed Meanwell type of enclosures on Thingiverse but without proper airflow and preferably short stand-offs from the surface of the PS 3DP or any commercial enclosure is a concern. |
