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.

    • Excellent design
Style: 30V 10A
Functions at a high level, controls give finite adjustment of both voltage and current. No visible test LED flicker at low current levels, runs cool at normal power levels, fan stay off until more then 50 watts is used. Like the GND banana post, wish it came with a flat jumper to connect to the NEG post, but a wire works just fine. Lots of features, great value for the $. ... show more

I’ve been watching Rossmann for several years and fixed a few easier soldering jobs on some MacBooks, but my own died recently and I wasn’t able to figure out what caused it. Decided it was finally time to bite the bullet and get a power supply, and this worked out perfectly. Was able to inject voltage at an amp and quickly see a capacitor getting hot with my little thermal camera, and order a replacement and fix it! Now I’m thinking of other things I can use this for, next on my list is fixing up some old power tool batteries that won’t charge, seems manually charging the cells is safer and this will work well for that too. ... show more

It blew its' line fuse so I put a new fuse in it. It immediately blew that one. I bought this power supply back in the middle of August and it was out of the return period. I noticed a sound like a screw rattling in the case so I tool the case off. I found that the varistor had self-destructed. I hope that I can find a replacement for the component labeled "NTC1". It may be that it will come back to life if I replace it. Maybe the vendor will volunteer information about this part when they see this review. Attempted repair by replacing the NTC1 5D-15 with a 5D-20. It still blows fuses so I suspect that a power mosfet has shorted. I have received an offer from the vendor for a refund or replacement. ... show more

Using this neat little machine to fix some batteries and do some electro plating / precious metal recovery. Controls work accurately, it's lightweight, and fits on a small shelf. I enjoy the extra ports for USB. I haven't had any issues in two runs, several hours of sustained use. So far, worth every penny. ... show more

Useful for testing the functionality of small electronics and diagnosing power-related issues. Allows for fine tuning of both amperage and voltage with over current protection for peace of mind. It's a modestly-sized unit and doesn't take up too much space. The power cord is detachable and uses one of the standard appliances NEMA cords. The leads are a little loose when plugged into the unit, but maybe that's by design. Added ground if desired. Leads feel to be of good quality and have ample length. Interface is easy to use. NOTE: The knobs are also buttons! For some bonus, includes fast charging USB capabilities built into the front which I guess is a nice tough though not necessary. ... show more

    • Very useful to have
Style: 30V 10A
Over the years I have had to test different electrical and electronic devices by using batteries or different setups. This has mostly eliminated the need for this. I tested the output, at different voltages, with a calibrated Fluke 289 meter and found the output to be spot on. I have also used this to “wake” dead batteries when a battery charger wouldn’t recognize the battery. Excellent value. ... show more

*** 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. ... show more

    • Solid power supply for a budget.
Style: 30V 10A
I got this to help me force a charge onto some cells in a drill battery that didn't want to take a charge. Easily programmable, and accurate within the tolerances I needed. Hard to beat for the price.
