We have our own R&D patent and professional production factory. Standard and strict quality control is our aim. NANKADF dc power supplies have always been upgraded and innovated in the field of expertise. Whether you are an engineer in a specialised field or an electrical enthusiast, it is the perfect partner for you. NANKADF dc power supply uses high-quality built-in circuit board and a sturdy, anti-drop shell. Accurate encoder adjustment meets the high requirements of professional electricians. Multi-layer safety protection, simple and convenient operation, it is also the best choice for beginners and amateurs. Precision encoder knobs allow for quick adjustment of voltage and current parameters, enabling greater efficiency and more precise control. Parameters can be set directly without disconnecting the load. The output lock prevents damage to the load caused by forgetting to turn off the output If a short circuit occurs in the load or power supply, the power supply will automatically stop outputting power and sound an alarm. When the operating temperature of the switching power supply reaches a certain level, the cooling fan will automatically activate. ## 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 | |---------------|-------| | Amperage | 10 A | | Asin | B09P1CJV42 | | Best Sellers Rank | #6,732 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #5 in Lab Power Supplies #6 in Life Science Supplies | | Brand | NANKADF | | Built In Media | DC POWER SUPPLY，Output cable, power cord, manual | | Color | Black（Memory Presets） | | Connector Type Used On Cable | usb | | Customer Reviews | 4.6 4.6 out of 5 stars (1,142) 4.6 out of 5 stars | | Enclosure Material | Shell | | Form Factor | benchtop | | Item Dimensions | 5.31 x 7.68 x 10.43 inches | | Item Weight | 2.5 pounds | | Manufacturer | NANKADF | | Maximum Power | 300 watts | | Mfr Part Number | NPY2 | | Model Number | 0-30v 0-10a | | Output Current | 10 A | | Output Voltage | 30 volts_of_direct_current | | Output Wattage | 300 watts | | Specification Met | OCP | | Upc | 752895666402 | ## Product Details - **Brand:** NANKADF - **Color:** Black - **Material:** Shell - **Item Weight:** 2.5 Pounds - **Connector Type:** usb ## Images ![DC Power Supply, 30V 10A 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/71C6m2dNT7L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Should have bought one years ago -highly recommended. *by on Reviewed in the United States April 28, 2026* Easy to use, it has internal amp limit settings for LED and shorts. It is light, easy to set up. I used mine to test 200 PITA christmas lights quickly. That really saved time and money. No noise, very accurate and compact. ### ⭐⭐⭐⭐⭐ Great affordable test bench power supply *by on Reviewed in the United States July 31, 2026* This item works really well. It is a great affordable work bench power supply. It's incredibly straightforward to use, and is easy to connect to. The power provided has been stable in the times that I've used it, so I like this device. ### ⭐⭐⭐⭐⭐ A Huge Upgrade Over the Tiny Cheap Power Supplies I Started With *by on Reviewed in the United States May 27, 2026* The Encoder Knob Feels Much Better Than ButtonsI didn’t think I’d care much about the adjustment style, but the encoder knob makes changing values fast and smooth. It feels way less annoying than repeatedly pressing tiny buttons to move voltage up and down.Output Enable Button Is More Useful Than I ExpectedThis ended up becoming one of my favorite features. I can set voltage/current first, then enable output when I’m ready instead of connecting live power immediately.That feels a lot safer when working on unknown boards.USB Quick Charge Is Actually HandyI originally thought the USB ports were kind of a gimmick, but I’ve used them more than expected for:PhonesUSB-powered toolsSmall development boardsNice bonus without needing another charger on the bench.Feels More Powerful Than Most Beginner Supplies10A gives enough headroom that I don’t constantly hit current limits during normal electronics work. It feels much more capable than the tiny beginner units I started with.djustment style, but the encoder knob makes changing values fast and smooth. It feels way less annoying than repeatedly pressing tiny buttons to move voltage up and down. ## Frequently Bought Together - NANKADF DC Power Supply, 30V 10A 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 0-10a) - REXQualis Electronics Component Fun Kit w/Power Supply Module, Jumper Wire, 830 tie-Points Breadboard, Precision Potentiometer,Resistor Compatible with Arduino, Raspberry Pi, STM32 - AstroAI Digital Multimeter Tester 2000 Counts with DC AC Voltmeter and Ohm Volt Amp Meter; Measures Voltage, Current, Resistance, Continuity and Diode, Blue --- ## 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.de/products/406555773-dc-power-supply-30v-10a-bench-power-supply-with-memory](https://www.desertcart.de/products/406555773-dc-power-supply-30v-10a-bench-power-supply-with-memory) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-09-01*
