I'd not known about this issue. But just today after having my unit powered for 10 minutes I bumped the table and I get a CH1-Ch2 Error message. I'm in...

I must just have the worst luck with my unit then. :laughing: I've gone ahead and installed 2x 1uF X2 caps.   While it helps... the resistor still reached...

I did repeat the test here with just one meanwell LRS-150F unit attached. I received the same result, temperature rapidly approached >80C within a few minutes.

Adding a 1uF / 47R to one unit does appear to help me a bit. This is brings my results inline with your initial testing, R4 climbs to around ~45C.

I have very little experience with triac/AC circuits, but I've been poking around with my unit here. I added the extra snubber circuit on both LRS-150F's. And removed R1/R3. Is...

Thanks!

I'm really not having much luck with this module. :sweat: I'll just add this here, because it's on the same module, so might be related to the original issue? I...

Thanks for insight into the design. I suspect this end of holder got hot because it wasn't making perfect contact with the fuse, leading to an added resistance, especially considering...
