Features
- Precise encoder knob: HANGELL DC power supply 0-30V 0-10A is different from the ordinary traditional knob, which is adjusted by precision encoder knob, with high precision and strong stability. With coarse adjustment and fine adjustment, the number of digits can be switched by pressing the knob, and the value can be set by rotating the knob. It is more convenient to adjust the required voltage and current.
- Output switch button: The variable dc power supply is equipped with an output switch button, so you can easily turn on or off the output by pressing the output button. You can check the working status through the indicator light on the display screen. When the output is turned off, the voltage and current data can be adjusted anytime and anywhere, effectively preventing the load equipment from being damaged by forgetting to turn off the output.
- Short circuit alarm: In order to improve the safety of lab power supply and prolong its service life, we designed a short circuit alarm device for DC power supply. After the OCP function is turned on, if the load equipment is short-circuited in the working process, the variable power supply will automatically stop outputting and send a buzzer to remind the user, protecting the adjustable power supply and the load from being damaged. Bench power supply also has safety protection functions such as overvoltage, overcurrent, overtemperature and overload.
- High-precision 4-digit LED display screen: The laboratory DC benchtop power supply is a professional laboratory power supply regulating device with high resolution of 0.01V and 0.001A, providing more accurate voltage and current readings. Constant voltage (C.V)/constant current (C.C.) mode automatically switches with the change of load. You can see the working status indicator on the display. It is clearly visible even under the condition of insufficient light.
- Packaging and after-sales service: The package includes: 1 x variable DC power supply, 1 x input power cord, 1 x output power cord, 1 x user manual. We provide lifelong technical support. If you have any question, please feel free to contact us.

works as it should, small size and accurate description, tested with a multimeter and output is extremely accurate as well

Excelente artículo, la fuente cumple es muy práctica , tener el switch al frente ya es bueno y lo segundo poder ajustar el voltaje y luego darle output , muy bueno tener la posibilidad de trabajar con o sin protección sobre un corto circuito.

I'm just a hobbyist so I'm sure that if I were trying to use this professionally I would have some different requirements, but for just powering random circuits it works great. The controls are kind of weird, but usable once you figure it out. It's difficult to see the labels on each knob because they're blocked by the knob itself. They should've honestly just had pushbuttons or something, the knobs make it more difficult to use. The "settings" are completely unintuitive and the manual is difficult to understand in places, but you can silence the beeping if you want. This setting seems to get saved even if you unplug it so that's good because I don't want to have to ever read the manual again. It comes with a set of leads with alligator clips but you might want to get a separate pair because they feel very cheap. The power cord it comes with is short but it's just a regular IEC cord you probably have a dozen of lying around. The USB plugs are always powered whether the output is on or not, in case you were wondering.

Works fine but I don't think it will output the full rated 5 amps @ 60 volts though. Might want to order the next one up from your needs. Also wish the power terminals had a cross drilled hole for wires.

*** edited to add *** Oct 19th 2024 I pulled out the power supply to test a linear actuator. The power supply blew up. This is now the second one to do so. This one had no buzzing sound, it just failed on the initial surge current to the 12 Volt motor. A power supply needs to be reliable. Failing on normal operation is a manufacturing problem if it happens the same way to different power supplies. I can no longer recommend this at all. As promised, if the second one failed I'm updating my review. I'm changing my review to 1 star. Cannot depend on it. My other power supply from a different manufacturer has worked far longer and under worse conditions without any issues. My reliable power supply is a Kungber (old style without the battery charging mode) SPS3010 and it has not let me down. It is just a few dollars more right here on Amazon and a far more reliable product. *********************** The first unit I had blew a fuse while testing the short circuit protection. Went out with a bang, dimmed the lights and made bad smells. It also buzzed a lot while delivering current so I'm thinking it had loose transformer windings and other issues. It was returned and the new one was tried the same way. This time, no noise, no blowing fuses and it just worked. I already have two variable power supplies of different types at home. At work I have some serious supplies, 12kW 0-400V AC/DC and arbitrary waveform with multiple phases. So I'm not a novice when it comes to power supplies. This unit is extremely accurate for voltage. It can be seen that it is not far off 1 LSB on my multimeter most of the range. The error is just as likely to be the meter as the supply. It has not been calibrated. The display on this unit is easy to read. The values are easy to adjust. I personally do not need the level of accuracy that this supply provides. I will stress that I have not tested it under load conditions, though that should make little difference to the readings. It is light, good looking, as in it doesn't look like some backyard hobbled up unit. I'm impressed. For a 10Amp 30Volt power supply, this has great performance for the cost. My only concern is the failure of the first unit. Maybe a bad luck sample, but it could also point to quality control issues. The particular sample I have now however performs flawlessly. Should that change, I'll revise this rating. The noise is primarily switching noise about 230mV peaks with 50uS or so period. So about 20KHz switching frequency at no load. I haven't done load testing other than short circuit tests to ensure it delivers the rated current, which it does. For a $60 power supply, the testing I already did tells me it is worth the money. You can do far worse than this and spend more money at the same time. There was no issue returning the faulty unit I initially received so that is a plus and I'd suggest stress testing it to make sure it doesn't have some weird fault if you purchase one. It is rated to provide protection against failures, so test them is my recommendation.

The media could not be loaded. Le doy 5 estrellas porque a mi me sirve para hacer pruebas en mi taller, tiene salida tipo C, se ve d muy buena calidad a pesar del costo, tiene protección contra cortos, se deja regular finamente, lo probé con mi multi tester , le coloque una resistencia y mide el consumo de la carga en amp y watts , con el mismo pongo a cargar mi celular y la luz led de la lupa de diadema que compre aquí mismo.
