DC Power Supply Variable, 30V 10A Adjustable Switching Regulated DC Bench Power Supply with Intelligent Charging Mode, 18W USB Interface, Precision Encoder Knob (Black)

Esto es muy bueno y fácil de utilizar

I have used this a lot and I really like it. The value was good, and it seems to be holding up well to my occasional use. I do not use it every day. The voltage adjustment is easy on this unit. The cords seem like they are good quality, flexible, well made. The display is plenty bright and easy to read. I would recommend this to a friend and if mine ever goes bad, I would not hesitate to buy this again.

I'd like to start out by saying I am new to the hobby of electrical engineering and this DC PSU is the first I've ever bought and operated. Upon opening the box the PSU came in, it becomes evident that actual thought and care was put into ensuring the protection of the product during shipping. It is safely cradled by 2 large, thick, foam cutouts and it is wrapped in a sheet of plastic. The power supply has a very nice look to it and is incredibly light. It would be easy to transport it in a backpack, which is fantastic for college students.Something that stood out to me especially, was the 2 cards that come in the box. There is a guaranteed lifetime warranty on one card and a monetary incentive to review the company's product on the other!! Now that is classy! It just shows how invested this company is in creating an outstanding product they can be proud of and that they truly want to hear what the end users have to say about their product. They appear committed to finding ways to better the quality and user experience of their products.The manual it comes with is well written and helpful in describing the safety precautions and specs of the PSU. One thing I would like to see updated however, are the instructions for setting the current and voltage limits. They give a brief example but it wasn't super helpful for someone like me that is inexperienced with operating a bench power supply. There also seems to be not very many tutorials on youtube either, but maybe I'm just a little slow on the uptake.After some trial and error I managed to get a fair idea on how to properly operate it. Once I got the hang of things, it became apparent how accurate and high quality it is. Gives smooth, controlled output. I do however have a few criticisms. There should be an indicator on or near the adjustment knobs that indicate the minimum, maximum, and middle position of the dial. Can be difficult to tell how much I've turned it, especially if I walk away for a while and would like to quickly resume at the knob adjustments I had previously set before powering off. Another qualm I have is that the coarse adjustments are very sensitive and can be easy to over or undershoot the output value I want. The fine adjustment knobs also don't have a very large range so they can make finding the exact value I want tricky due to the sensitivity of the course knobs.It would also be nice if the power switch for the supply was located on the side, front, or top of the supply instead of on the back. A nice feature for safety too would be to have a button or switch for stopping the output of the supply while leaving the PSU on at its set values so that I don't have live leads that are constantly on and can be a hazard if they were to fall or be bumped into. There is also a short delay in the changing of the supply values after turning the knob as well that could be problematic.Overall this is an exemplary power supply, especially at this price range! I would definitely recommend this product for any new or experienced hobbyists.TO RECAP:PROS:1. Quality packaging2. Excellent product design and materials3. Well made manual4. Professional and invested company5. PriceCONS:1. Manual could have better explanation of operation2. Power switch location3. No output cutoff switch for when supply is on4. No position indicators on adjustment knobs5. Small delay in output value in response to user adjustment6. Sensitive coarse adjustment knobsI would rate this DC bench power supply as a 7/10. Definitely a great choice!

Perfecto. Muy buena calidad

Fantastic power supply. Very easy to use and so far very accurate. I was suprised how light weight it was for its size, I guess I expected some heavier components.

To begin with, you're not going to find a power supply capable of supplying 60V at 5 Amperes anywhere below 4X the price this puppy is sold at !!! Hands down the best deal on the market. At $75 each, I'm actually looking to buy a second unit rated at 120V, 3A. Initially I was looking at Power supplies with dual or triple outputs, but they were all no less than $350 each - especially at current values of 5A or higher. This is the best deal for the $.There are a few small issues that I would hope the manufacturer will address quickly to make these units absolutely perfect. The dials are missing any VISIBLE tick marks (or at least the half way tick marks) on them - The tick marks that you see on my photo attached here - I had to paint-on myself after calibrating the ranges on both the voltage and current knobs. This is very important when setting an exact Voltage level or a Current Limiting value in CC mode or CV mode and always running out of the fine adjustment range because you have no idea where your fine or even coarse level marks are on the dials. Easy fix for the factory, but an important one for the customer.Secondly, the spacing between the ports are non-standard for any BNC-type banana plugs! This has absolutely no affect on the performance of the unit, but for those engineers and technicians who may have dozens of BNC banana connectors to re-use (instead of buying new ones) they will NOT fit as you may see on the picture! This would be a minor fix at the factory level, but an important one for many customers who have dozens of banana connectors to re-use.Finally, there is NO push-button to disable supply to all outputs if necessary without turning off the entire power supply. The only way to do that is to turn off the power supply. Presence of This option alone would make this unit an excellent supply for the money!Otherwise and excellent little power supply at a price that can't be beat for such high supply currents at high voltages !

The media could not be loaded. For me I bought the Kungber SPS3010I read the instructions and went through the procedures for setting the Volts and Amps and nothing was working for me the way I wanted my circuit to work, but now it is and I'll explain.What I did was to turn off the PS.Turn both knobs to the left so they are at the lowest setting.Turn on the PS and the display will all be zeros and the CC led will be on.Turn the CC knob to the right course and fine, and you will notice the CV led will be on.So right now Amps is set to max and Volts is set to zero.Hook up your circuit and and start adjusting the CV V knob cause it will be set to zero.Nothing happens without voltage. When I started adjusting the CV V knob and bang the circuit worked as expected.The Current adjusted per the instructions and the circuit itself, all I have to do is adjust the voltage knob.
