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

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.

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)).

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

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.

Adjustable DC Power Voltage Converter AC 110V-220V to DC 0-48V 10ABy any decent standards, this product has none. output maxed @ 45Vdc. providing power to 4 LED strips, wire spec #22THWN 3 feet long, each. within 10 seconds of the first power on that concise odor of failure began, right by the screw terminals, right behind them. Set output to 42Vdc for the remaining 9 minutes, the LED voltage displayed steadily until, well, the LED strips began to flash, then RIP, toast, smelly toast. I do not recommend this item, for any necessity.I've purchased many of this slightly open frame PS. this brand is new to me which I cannot justify purchasing this brand of any item, neither should you.I bet they cheeped out on the potentiometer

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.

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.
