Review on 💡 Enhanced MEAN WELL RSP-1000-48 AC to DC Power Supply 48V 21 Amp 1008W with Power Factor Correction (PFC) by Michael Thaxton

That would be 5 stars if it weren't for the fact that the fans are too loud for me. They run all the time and accelerate under load. I'm sure MeanWell designed the cooling system to match the power dissipation, but my application runs at a relatively low average power and only needs full power intermittently. The output power of 1008 W was also a bit excessive. I ended up returning this power supply and buying one of MeanWell's conduction-cooled versions, the UHP-700-48. This source cannot deliver full power at 120VAC (it requires 240VAC), but it has enough output power for my application and is completely silent, which is more important.
