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.

Description

Hangell DC power supply is very comprehensive in terms of functionality. We have always prioritized the reliability of quality, using a metal body, safe and stable electronic components to ensure the stability and accuracy of the DC power supply, with lower ripple and noise. With multiple security protections at the same time, it will become a good helper for you in laboratory and industrial applications. In order to facilitate widespread use by customers in different regions, our DC adjustable power supply adopts a dual input voltage function, with an input voltage selection of 230V/115V. If you are in an area with an input voltage of 110V, you will need to flip the switch to 115V. Choosing the wrong option will affect the user experience of the DC power supply. DC power supply uses encoder knob, which is convenient for setting data. Both voltage and current have coarse and fine adjustment methods. The setting is faster, which saves complicated operation and is more convenient and accurate than the traditional knob. Output enable/disable switch: convenient for adjusting the output status of the power supply at any time. When the DC power is turned on, the default state is not output. When you press the "output" button, the indicator "OUT" in the screen turns green, indicating that the power output is turned on. When you do not need to output, pressing the "output" button again will turn off the output. The output button can prevent us from forgetting to turn off the output and causing load damage. OCP short circuit alarm: When the adjustable power supply or load experiences a short circuit, the power supply will automatically stop outputting and emit a buzzing alarm to remind the user. Effectively prevent damage to the variable DC power supply and load. Intelligent cooling fan: The cooling fan helps to reduce internal temperature. When the working temperature exceeds 122 ℉/50 ℃, the cooling fan will intelligently turn on, extending the service life of the equipment. Low noise: This bench power supply adopts safe and reliable electronic components and a new circuit design, which will make the noise and ripple of the power supply very low. 10A fuse box: The back of the benchtop power supply is equipped with a replaceable fuse, providing perfect overload protection and short circuit protection. Ensured the normal operation of the circuit. Our DC power supplies have the advantages of high quality, high performance, innovation and reliability in the market. We pay attention to the details and quality of our products and have gone through FCC, CE, ROHS, to ensure that each product is in line with customer expectations and needs. We have received high praise from professionals and a wide range of enthusiasts, and have a high level of trust in our products. We are committed to providing customers with high-quality service and support to ensure that customers get the best experience and results when using our products.

  • Promising Fun! Be Responsible!
Style: 30V 10A
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

  • Fantastic tool for variable use in the workshop
Style: 30V 10A
Excellent tool for the workshop workbench. I love being able to adjust the voltage and amperage. This has allowed me to test so many other items than my old 12volt power supply. I've even been able to repower totally dead rechargeable tool batteries. This has worked on my Ryobi, Milwaukee and DeWalt batteries. This Variable Power Supply is now a permanent fixture on my workbench. ... show more

  • Works great!
Style: 30V 10A
I love this thing. I mess around with alot of used/old tech and many come without the power packs. With this I can dial in the volts and amps, even below 1amp. It even has an alarm if you cross live wires. It was a good buy!

  • Need a tightly controlled DC voltage? This’ll do!
Style: 30V 10A
This thing is awesome! I just wish I knew how to use it. My ignorance should not reflect poorly on the product. It is light, durable, and the controls are easy to manage. I have used it for troubleshooting circuit problems and also for rust electrolysis on a whole bunch of tools in my barn. I recommend this product for DIY’ers ... show more

  • Basic bench supply
Style: 30V 10A
Works ok, regulation and ripple are what you’d expect for the price. It has some issue starting up when current limit set below 100mA. For example, set it to 5.00Vdc at 0.020A with a small load (LED and current limiting resistor) and it will go right into overcurrent mode when enabling output. Circuit should only be drawing 15mA or so. Same if no load at all. I thought it was defective until I turned current up to 100mA. Not a deal breaker for most cases; just something to be aware of. ... show more

  • Amazing for its price point!
Style: 30V 10A
This power supply is way better than it should be for its price point! Nice heavy duty case with plenty of ventilation, huge cooling fan, and good strong buttons with a nice easy to read face with very crisp digits on the display. I also like that it has an overcurrent protection and cutoff switch for the output. First class all the way! ... show more

  • Good for hobbyists
Style: 30V 10A
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. ... show more

  • Failures at Rated Power Output
Style: 30V 10A
Problem: Supply limited to a maximum of around 145 Watts output and not full RATED power (300 Watts) . Supply Voltage 115 VAC. All 4 supplies, had the same exact failure mode -- current becomes permanently limited to 7A maximum with a 10A set CURRENT LIMIT. When first tested, all could supply 10A at about 28 VDC to the same exact resistive load bank before they eventually failed. It is caused by a wire de-soldering itself from the voltage selector switch -- due to extreme heat (at least 360 F) caused by high contact resistance within the switch during higher power output and additionally case internal temperature. Without the switch being able to complete the circuit for 115 VAC input, it will assume 230 VAC input. This causes the problem. Initial measurements before failures: Input power 350 Watts, 4.2A, 512 VA @ 0.68 power factor into a DC resistive load. 4 failures in a row could indicate a underrated switch that can not handle the 4.2A continuous current at higher power output levels. There are no markings on it to indicate ampacity. While this switch will initially handle the supply's rated output current of 10A, it will eventually fail unless using lower power settings. The switch is a double pole double throw type and if one pole is damaged, the other spare pole could be used -- but probably will have the same problem later. Solution: Solder the two switch wires together (assuming 115 VAC supply) and heat shrink insulate the joint. ... show more
