48V DC Output Industrial DIN Rail Power Supply 5 Amp NDR-240-48 240W Input Voltage 100 to 240 Built-in Active PFC Function

Very nice power supply when a higher amperage is needed for some POE devices. I use this to power several PTZ cameras and it doesn't even get warm to the touch. Very useful and nice power supply.

Worth every penny being used for my Mikrotik RB5009 router. Has been continuously running for several months now and nothing negative to speak of at all!

There isn't much to say about it. It provides 48v power for a small CNC system in my garage. The power is stable and clean, and those are my main requirements. There is an adjustment pot for fine-tuning the output voltage that can be finicky, so be careful. I pushed the screwdriver a little too hard and had to open the box to move it back into position. It is a free-floating pot with no support; be gentle. This is the one poorly designed item I found on the supply. I docked it 1 star due to the adjustment screw, but I would have been just as happy giving it 4.5 stars if I could. Overall, it performs well and does what I need.

I've been running this the better part of a week for some networking equipment. So far it's working just fine. As others noted, the adjustment pot is a bit fiddly but it does the job. Odd that the front panel marking above the pot says 28 volts, not 48. The fit to the din rail is not super tight. There is some play but it holds and doesn't come loose with a hard tug. The latch works as it should. Overall build is solid and well made. Screw terminals for AC in on bottom and dc out on top are solid and work well. Overall, it works as expected. It runs cool and doesn't generate noise in nearby radio equipment. For the money, it does what it should.

This rail mounted power supply works as advertised, though it is worth noting that it has no markings of any official testing lab such as UL, ETL or similar. It does have a CE mark, though that is typically self-certified. It does not inspire confidence when the front panel label shows 24-28V for the voltage adjustment potentiometer when it is a 48V power supply. Obviously a misprint, but it says something about the quality control.
