Adjustable DC Power Voltage Converter AC 110V-220V to DC 0-48V 10A Module Switching Power Supply Digital Display 480W Voltage Regulator Transformer Built in Cooling Fan

Great power supply. Adjustable output output to 48VDC. Plenty of current (10A) to power most electronics. Easy to use, safe, and reliable.

Perfect replacement!!

It works, using it as an adjustable power source for my electronics bench. The voltage adjustment can be a bit finicky and the found does get loud and stays on, but all in all, good for the money

I love this power supply. The variable voltage is great feature. I checked the voltage with a multimeter and found that the displayed voltage was very accurate. Many people mentioned the sensitivity of the knob. It's true that you can make very fine adjustments with a light touch. It would be nice if the knob had a bit more resistance to prevent unwanted adjustments. Be aware there is no user manual or power cord. So you'll need to be resourceful.

Really nice to have adjustable power supply. Good for bench testing stuff

FANTSTIC, One of the best bench supplies I've ever used. Very stable and does what the specs say it will, and stay cool too. Great value, I now own 2 two of them and may get another before the price changes. Bought the first one over 3 years ago & it's on 24/7 to power my security cameras, Analog 2mp PTZ EVERSECU HI Speed domes on 200 foot extensions (36v at 8Amp max load(typical ~3 amp)).

After reading some of the reviews decided to check out the inside of the power supply and found a few issues. 1: The knobs were plugged in opposite of each other (the voltage knob was plugged into the 3 pin connector for changing the amps and vice versa) 2: in the images for this power supply there is one that shows 5 capacitors towards the front of the power supply (I only have 3 and 2 open spaces where capacitors could go) 3: the mosfets in the back are shielded with something however the 2 on the front left side of the enclosure are right up against the outer casing 4: the + and - wires for the display weren't connected at the solder joints on the circuit board which is affixed to the top piece of the enclosure with a sloppy blob of the white goo used in electronics and there was a thin piece of transparent film (about a 1 &1/2" X 1 & 1/2" square that I believe was supposed to be protecting the display pcb, however it was not even covering it and was held to the top of the enclosure by the same white goo as the display board. Last but not least 5: one of the windings looks like they ran out of material and just wrapped a U shape around one side while the other side is completely wrapped with copper wire. Gonna repair the solder on the display wires and hopefully have a working psu

0-48v at 10 amps for under $40? Not bad. I did not expect a voltage readout display and an optional potentiometer that you can remoter mount for voltage adjustment. The display is on the top of the supply. However, be advised that like all switching power supplies there is some noise in the output. I could not measure this noise accurately with my inexpensive scope. However is was visible on the scope display and would increase as you raised the voltage. Attaching a dual wound toroid choke on the output that I salvaged from an old PC power supply, I was able to drastically reduce this noise.

Produit relativement fiable et performant pour le prix

No me gusto y no tienen devolución de equipo dañado por mal empaque

This unit worked for a while, then smelled like burned plastic before completely failing. Junk.

fan no work

This adjustable DC Power Voltage Converter meet my daily usage. So far so good as expected voltage and current no issue.
