⚡️ MYSWEETY Adjustable DC Power Voltage Converter - AC 110V-220V to DC 0-48V Module Switching Power Supply with Digital Display, 480W Voltage Regulator Transformer and Built-in Cooling Fan Review

In the photo the GREEN charge controller outputs 58.19V*1.85A=107.6515W even though it is set to 63V*6A=378W but can only do 35.3V*4.465 Consume A = 157.6145 watts from the PSU, even when the PSU is set to maximum power (which shows 52V on the display with no load).

If you need AC power this is a very good power supply with good regulation and a very wide power range. An additional feature that I didn't see in the display is that it comes with an additional 3-pin potentiometer so you can use the remote's potentiometer to adjust the output voltage. There is also a bright three digit voltmeter on the case that reads within plus or minus 0.2 volts of the actual output signal. Can't comment on durability as I've only just started using it, but I had a 50W load

Upon opening the box I immediately found an extra potentiometer and a wire attached to it. For example, during the first test, which ran at the specified current limit, the entire power supply smelled as if it had burned out. The internal built-in small potentiometer burned out. with a spare pot and extra heatsinks on the outside of the frame where the really hot stuff gets attached with hot melt. We ran another test at the specified current limit and the new radiators dissipated the heat and…

Died in less than an hour of actual use - load was 16v at 2 amps / 32w. About 1/10th the listed rating. I suspect , most people buy this one uses a lot less than this one or just don't update the review when it fails. The PSU seemed very good at first, tested several times with no problems. However, when I actually put a load on it after that it started to about 10 minutes the voltage started to drop and then poof!$43 is gone.I bought this a year ago for a project I'm finishing up so I doubt it

It works as expected. A few things they could improve. It would be nice if the potentiometer knob was bigger to make the voltage setting easier to set for fractional values (especially at lower voltages); A small number of knob turns will result in relatively large voltage changes. In addition, the accuracy of the voltage display is reduced by 300-500 mV. (Regardless of whether you have a multimeter or don't need to set the setpoint precisely. And it would be nice to be able to limit the…

Pros: Voltage measurements are accurate. I was expecting a few percent. Nice that it is integrated into the case. It also seems to handle the power output, although I didn't have anything large enough to test the full 480W. It comes with an additional potentiometer to adjust the voltage. I'm not sure why. Maybe it's for installing in a different installation location. The fan will not turn on until it warms up or there is a significant load. In fact, I haven't even heard him make a sound. Maybe

I make this power supply a workhorse, running the output through a full wave bridge and relay to protect the output of this unit from solar voltage, and running voltage into the input of my MPPT which also drove the panels the voltage that allows the MPPT to manage the charging of the batteries so that only one device will service the batteries. Operating on a 24v system with 560w panels and using 5 amps from the power supply in charge mode only, otherwise the charger is isolated by a built in…

My CNC spindle loses power and cannot be used. I found and ordered this power supply from Revain. The first came with dents on the box and case. I asked for a replacement and it came the next day. This time it's perfect and works flawlessly with my CNC. Although marked 48V it can be set to 50V if required and also has an LED display to show the voltage. It should be noted that as it comes with a 230V AC setting it needs to be set to a 115V input for use in the US. Other than that I don't see…
