Meanwell-Megawatt-Cheapowatt VENTILATION
All of these units must be raised up so they do not sit flat against the floor. They need feet at least 1/4" tall. Now owning all three types I can vouch for the fact that laying flat decreases air fl...

I thought it was fairly obvious that the casing of these power supplies were used as heatsinks for the transistors.
Since my Meanwell rsp50015 is on my cabinet door, I wanted some stress relief on the input and output power cords so as to not repeatedly stress the circuit board wiring receptacles. I had some aluminum window screen sections left over, and used these to attach the input and output cables. They are just over 1/4" thick and add some small percentage to the heatsinking, and of course allow airflow underneath the unit.
Thanks to Westend, I have lots of large finned heatsinks, I just have not shaped and adhered them to the casing adjacent to the transistors to assist heat removal.
It has to be over 70F and maxed out at 41 amps before my Meanwell's loud and powerful 40MM fan powers up. Otherwise the two quiet Noctua fans work admirably, and the unit does not really get warm providing 20 amps anyway.
I love my MW power supply. So do my batteries.
No Automatic underchargers for me.
