Adjustable DC Power Voltage Converter AC 110V-220V to DC 0-48V 10A

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

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)).

I ordered a second one. I liked the first one, it works fine after a couple months, but I have it under a light load- about 50 watts of LED lights. I like that is essentially operates as both a dimmer and power supply with my LED strips. . It seems clear that for me, I wouldn't use it at full power. Fan is reasonably quiet, and doesn't come on when the unit is cool. Rarely comes on at all at 40 volts and ~50 watts. The potentiometer allows adjustments to .01 volts, and isn't too overly sensitive. But based on the size of the wires, I suggest buying a bigger supply if this one is going to be close to it's limits. I took one star off for my lack of full confidence if I was going to use at full power.

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.

The "extra" potentiometer that was included was especially appreciated. This allows you to place the voltage adjustment at a distance from the power supply itself. In my case, the power supply is under a control panel and the voltage adjustment knob was placed on the top. Allows for a "clean" looking control panel. The voltage indicator (voltmeter on the supply) is also appreciated. Very convenient during initial set-up and will be again if any troubleshooting is required. In my case, I needed to limit the output voltage to 20 volts. I added a voltage divider for the remote voltage knob so that the power supply "saw" the correct resistance AND I could limit the range. All in all... a well-designed power supply.

I was having difficulty finding a 220 ac - 32 volt dc transformer for less than $200. I tried this because it is adjustable and low price so if I blow it up no great loss. To my surprise it works awesome. Thanks!

It works so far, but we will see how long. It was purchased for an amplifier test project (48v). Wanted to confirm viability before buying a good quality supply.

Perfect replacement!!

Produit relativement fiable et performant pour le prix

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

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

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

fan no work
