About this item

  • Upgraded OVP/OCP: We care more than you expect. Based on the original DC power supply, this new serie DC bench supply improved the Over Voltage Protection (OVP) and Over Current Protection (OCP) and added OVP/OCP button, provides more secure using experience. Activate the OVP/OCP of the adjustable power supply, if the output voltage/current is higher than preset (or short circuit etc.), the DC regulated power supply stops output automatically and sounds beeping alarm, the display flashes OVP/OCP, provides real-time protection for the bench power supply. To turn to general mode, just turn up the voltage/current or disconnect load (when short circuit is detected) and repress the OVP/OCP button
  • Output Switch: Sometimes we need to switch between different voltage or current outputs in experiments or work, but we often forget to turn off the output and causing damage to the load. The adjustable DC power supply OUTPUT switch is designed to solve this problem, just with a single press of the added OUTPUT switch, you can easily turn the output on or off. You don't need to disconnect the load or turn off the power each time, making the variable DC power supply more convenient and efficient to use. Kindly Remind - For safety consideration, the DC power supply comes with only 110V input which meets the US standard voltage. 220V input is NOT available for this bench power supply
  • Precision Encoder: Unlike ordinary potentiometer knobs, this DC power supply variable features with high precision encoder adjustment knobs that has strong accuracy and stability. With coarse adjustment and fine adjustment, the number of digit can be switched by pressing the knobs, and the value can be set between 0-9 by rotating the knobs, you can set the desired voltage and current on bench supply effortlessly. The required voltage and current can be adjusted without actual output power, which makes this benchtop DC power supply more secure and more energy saving
  • Mute Function: The DC power supply features with encoder knob adjustment beeping sound by default, helps you know the real-time adjustment progress of bench power supply.

This is a very well-built benchtop power supply. It functions as you would expect such a thing to. I haven't had any issues with mine and I don't anticipate any either; NICE POWER is pretty nice! I think this power supply is competitively priced, especially with the current coupon. I certainly recommend this unit, even without the coupon!

The NICE-POWER DC Power Supply is a solid addition to any workbench. With a variable 30V 5A output, it provides precise control for a wide range of projects. The adjustable settings and built-in encoder make it easy to fine-tune the power output, while the output switch, OCP, and OVP features add an extra layer of safety. I also love the inclusion of USB-A and Type-C quick charge ports, which are perfect for charging devices on the fly. It’s a well-built, reliable tool for both professional and hobbyist use!

I currently work in I.T. and have been using this power supply quite often. I work on radios, laptops, AVL's and more. I frequently get hardware to repair with missing or damaged power supplies. This is where this unit comes in and saves the day. I've saved so much time not waiting on a power supply to arrive and can get to work immediately. It not only saves me time, but also money. I can determine whether or not a unit can be repaired and then decide to buy a power supply afterwards, not beforehand, and ending up with multiple PS's sitting on the shelf. I mostly use this on ICOM, Kenwood and Motorola radios. It's very easy to use and dial in the correct watts/amps If you work in electronics, repairs or testing, I would highly recommend getting one of these. If you're just prone to losing your adapters, this can be a one and done unit for you. I'm very happy with this..

This DC power supply exceeded my expectations. I tested it with three loads: powering a 12 V / 30 W heated food bag, float charging a 5.5 A-h UPS battery at 13.6 V / 0.5 A, and powering a cordless power tool work light at 18 V / 1.3 A.The voltage and current displays were accurate to within the combined tolerance of the power supply and my multimeters, see photos.While supplying the heated food bag at 12 V / 2.57 A, I reduced the current limit to 2.5 A. With over-current protection (OCP) disabled, it seamlessly switched from constant-voltage to constant-current mode and reduced the voltage until the supplied current matched the limit exactly. With over-current protection enabled, it sounded an alarm and disabled the output when the current limit was reduced below the current being supplied.Float charging the UPS battery also worked as expected. With the battery initially at 12.6 V and the power supply set to 13.6 V / 0.5 A, it started in constant-current mode while the voltage rose to 13.6 V, then switched to constant-voltage mode as the current dropped.The USB charging ports provide well-regulated power. I measured 4.95 V with no load and 5.05 V while charging my phone at 1.85 A.The power cord is a bit short at just under 4 feet. Fortunately it's a standard IEC 60320 C13 connector (same as most desktop computers) so if you need a longer cable that's an easy find.There is a shrill BEEP upon power-up, and by default, at every digit change. The first thing you'll want to do is to press and hold the "V-Fine" button to turn that off. Unfortunately, it does not remember that setting, and you'll have to do that after every power-up. This isn't enough to subtract a star though. Overall I'm very happy with this power supply.

This is a really great variable power supply from NICE-POWER, I hadn’t heard of the brand before picking it up, but honestly I was pleasantly surprised at the quality of the power supply for the current list price of 50 bucks. The power supply is pretty bare-bones in terms of features, but does have a few fancy features that are nice to have, which at this price point I didn’t even expect to get those. The power supply is fairly well built, heavy enough to stay put on my work bench, and pretty compact so it doesn’t take up half my desk. The power supply has a nice on switch, the terminals are easy to connect to with the included leads. The adjustment knobs feel great and are responsive, and are clicky so you can adjust each digit of voltage or current to your choosing.Testing this out with my multimeter at max voltage of 32V, my meter read 31.7V, so only 0.94% off, for current I saw a 2.1% error compared to my multi-meter, but still not bad at all, and you can always fine tune to account for the error. The power supply has over-voltage and over-current protection if you need that for your loads, and testing it it worked great, the power supply cut off over the set points (these are easily adjustable), the power supply beeps until acknowledged and cuts off power when the alarm is triggered. Continuous current mode and voltage modes work great and has an annunciator light on the screen which is nice.Wish I had this when I was a student, but as an engineer for me it comes in handy if you need to test out devices or mock up a circuit. Overall this power supply looks great, works great, pretty accurate, and is compact, love it so far, definitely recommend checking it out its a great value.
