I have acquired a brand new MTH PS1 fan-driven smoke unit (part # AA0000011). The original thought was to drive it with my Mean Well LRS-150-12 (Input: 120 VAC Output: 12 VDC, 12.5 A) power supply. I have determined that 12VDC isn't quite enough power to make it smoke (fan does run). I was able to get to function correctly at 15 VAC (it will run on A/C or D/C).

I'm curious how you determined the MTH PS/1 smoke unit doesn't work on 12VDC. That flies in the face of my quick test here. I tried a second one with the same results. AAMOF, I've previously run these on 12VDC and had no issues.
