In particular I wanted to use it to test a rain gauge with LCD display designed to work off of two AA batteries...sort of 3.5 volts down to 2 volts. I wanted to measure the discharge current drawn by the rain-gauge electronics as a function of voltage as the battery discharged, and describe the LCD display brightness and contrast as a function of voltage level. With my other low-voltage bench supply, dialing in a particular voltage in a real hit or miss operation. The course knob always overshoots, then I find that my desired reading is out of range of the fine knob...so I go back and forth several times to get the reading I'm after. The unit was a dream. You just set the knob to control the digit you want to control and it just steps precisely for each click of the knob. In my case I wanted to test in 0.1 volt increments starting at 3.5 volts and dialing slowly down to 2.0 volts. I just set the voltage at 3.5 volts and the knob for 0.1 volt increments. Each click dropped the voltage exactly 0.1000 volts. Infinitely better that my other power supply. The second thing I like about this supply is the second on-off switch on the output...separate from the power on-off for the unit. Another. 50-year-old very-low voltage supply I have has this feature and I use it all the time. With this feature one can set the voltage and current level while the test unit is plugged in and also turn the test voltages on and off without going thru the transients of turning on-off the power supply. Very helpful. I checked the voltages and current w.r.t. my digital multi meter and the agreement was good. However, don't expect it to accurately measure currents of just a few milliamps. For that I used my digital multimeter. Highly recommended! Review: Got to be one of the best rectifiers - I built my own jewelry plating machine and chose this rectifier because it was in the voltage and amperage range. Plus it’s one of the most aesthetically appealing rectifiers out there. I have clients come into my studio so I built my own jewelry plating machine, but it looks more like a piece of furniture than a tool. I also wanted to rectifier that kind of had a nice aesthetic appeal. This rectifier works amazingly I highly recommend it. It’s so easy to use. I did buy an extra set of leads with banana plugs on them with a little higher gauge wire, but it’s really nice having the output switch right there cause I can turn the output off immediately after I’m done plating a piece of jewelry absolutely fantastic machine would recommend it to everybody. The price is great. You’ll love it. ## Features - Higher Precision and Easier to Set: This DC power supply has a precise encoder knob. The output voltage and output current can be continuously adjustable between 0 and nominal value by using coding knobs. The setting value can be also pre-displayed for easy use and adjustment. And it can display voltage, current and power at the same time - 3 Groups of Memory Storage: Different from general dc power supply, this variable power supply is equipped with three groups of internal memories. You can pre-set 3 groups voltage and current combination that you frequently used and then just recall the memories by pressing the button M1/M2/M3. This is a convienient design to save your time - Output Enable/Disable Button: When using the bench power supply, the output enable/disable button can prevent us from forgetting to turn off the output and causing damage to the load. Just press this button to turn on or turn off the output of the bench power supply. This makes it more convenient and more efficient to use the bench power supply - Reliable and Multiple Protections: This adjustable power supply comes with four powerful protection function including over-voltage, over-current, over-heat, short-circuit. Designed with perfect OVP and OCP short circuit protection, the variable dc power supply will automatically stop output and send a buzzer to alert the user when short-circuited of the load equipment occured. The stability and ripple coefficient of the variable power supply also work excellently - Various Application: The variable dc power supply is compact and lightweight and it only weighs 2.5 lb and measures 7.4 x 3.5 x 5.7 in. It also supports a variety of fast charging protocols. The adjustable power supply can be widely used in mobile phone maintenance, computer maintenance, battery charging, aging testing, laboratories, school teaching and production line as well as other requirements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09MVSJHY9 | | Amperage | 5 A | | Best Sellers Rank | #2,898 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Life Science Supplies #2 in Lab Power Supplies | | Brand | NANKADF | | Built-In Media | DC POWER SUPPLY，Output cable, power cord, manual | | Color | Black（Memory Presets） | | Connector Type | usb | | Connector Type Used on Cable | usb | | Customer Reviews | 4.3 out of 5 stars 174 Reviews | | Enclosure Material | Aluminum | | Form Factor | Compact | | Item Weight | 2.5 pounds | | Manufacturer | NANKADF | | Material | Aluminum | | Maximum Power | 150 watts | | Mfr Part Number | NPY2 | | Model Number | 0-30v 0-5a | | Number of Items | 1 | | Output Current | 5 A | | Output Voltage | 30 volts | | Output Wattage | 150 watts | | Specification Met | FCC, RoHS | | UPC | 752895666389 | ## Product Details - **Brand:** NANKADF - **Color:** Black（Memory Presets） - **Connector Type:** usb - **Item Weight:** 2.5 pounds - **Material:** Aluminum ## Images ![DC Power Supply, 30V 5A Bench Power Supply with Memory Storage & Recall，Variable Power Suppy with Encoder Adjustment Knob, 5V/3.6A USB Quick-Charge & OCP Short Circuit Alarm - Image 1](https://m.media-amazon.com/images/I/7136Y7th9vL.jpg) ![DC Power Supply, 30V 5A Bench Power Supply with Memory Storage & Recall，Variable Power Suppy with Encoder Adjustment Knob, 5V/3.6A USB Quick-Charge & OCP Short Circuit Alarm - Image 2](https://m.media-amazon.com/images/I/71CbPxQUnFL.jpg) ![DC Power Supply, 30V 5A Bench Power Supply with Memory Storage & Recall，Variable Power Suppy with Encoder Adjustment Knob, 5V/3.6A USB Quick-Charge & OCP Short Circuit Alarm - Image 3](https://m.media-amazon.com/images/I/71y-pkwLmYL.jpg) ![DC Power Supply, 30V 5A Bench Power Supply with Memory Storage & Recall，Variable Power Suppy with Encoder Adjustment Knob, 5V/3.6A USB Quick-Charge & OCP Short Circuit Alarm - Image 4](https://m.media-amazon.com/images/I/71FRjTg2tYL.jpg) ![DC Power Supply, 30V 5A Bench Power Supply with Memory Storage & Recall，Variable Power Suppy with Encoder Adjustment Knob, 5V/3.6A USB Quick-Charge & OCP Short Circuit Alarm - Image 5](https://m.media-amazon.com/images/I/71NzBEfj6FL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little Power Supply with Wonderful Voltage & Current Selection knobs *by R***S on September 14, 2024* I need a second low-voltage supply at our ranch for use in bench testing electronics at typical electronics supply voltages levels, sort of 1.5 volts to 18 volts.

Still working well. I don't use the USB charger or programmable features. I do use the 3 memory buttons on the front panel. Very convenient setting my frequently used voltages. The metal casing is like added bonus. The voltage reading seems accurate. The current is not accurate when at low values which is why I didn't give it 5 stars. I had an ammeter set-up and measuring 9.3mA but the power supply display shows 4mA. Would be nice if it was more accurate. Overall, happy with the product. Didn't see any electrical noise issues and very reliable. Using for over 2 years and still working well. ## Frequently Bought Together - NANKADF DC Power Supply, Bench Power Supply with Memory Storage & Recall，Variable Power Suppy with Encoder Adjustment Knob, 5V/3.6A USB Quick-Charge & OCP Short Circuit Alarm (0-30v 0-5a) - REXQualis Electronics Component Fun Kit w/Power Supply Module, Jumper Wire, 830 tie-Points Breadboard, Precision Potentiometer,Resistor Compatible with Arduino, Raspberry Pi, STM32 - FNIRSI 1014D Oscilloscope 2 in 1 Digital Oscilloscope DDS Signal Generator, 100X High Voltage Probe, 2 Channels 100Mhz Bandwidth 1GSa/s Sampling Rate Built-in 1GB Storage Space --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/424587076-dc-power-supply-30v-5a-bench-power-supply-with-memory](https://www.desertcart.co/products/424587076-dc-power-supply-30v-5a-bench-power-supply-with-memory) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-10-07*
