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

Would have gotten 5 stars if the fans weren't 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 provide full power output at 120 VAC (it requires 240 VAC), but it has enough power output for my application and is completely silent.
