Featuring an intuitive encoder knob, USB fast charging port, and comprehensive safety protections, it’s engineered for professional-grade lab work and electronics projects. Its lightweight, benchtop form factor and dual voltage input make it the ultimate versatile tool for engineers and makers who demand accuracy and reliability. ## Description Product Description NANKADF series laboratory switching power supply is a full-featured, simple and beautiful design of easy to operate power supply. The small body is made of high-quality components, the power supply itself has short-circuit protection, over-voltage protection, over-current protection, over-temperature protection and other perfect protection mechanisms, ideal for the majority of electronic enthusiasts and beginners to use. HD display Voltage, current, power three-line LED high-definition display The display has a protective film (you need to check it yourself because of the tight fit with the screen) Encoder adjustment knob Unlike the analog regulation of ordinary DC power supply, this power supply is regulated by encoder. It will make it easier and faster for you to set the power supply parameters. Power supply size and weight The size of the product is only: 5.9in*3.54in*7.48in Bare weight only: 2.64lbs The small size and mass of this power supply will not take up too much space on your workbench. Output on/off switch The power supply is configured with an output on/off switch. The setting of this button turns the output of the power supply on or off. And in case of short-circuit alarm, pressing can release the alarm and enter the off output state. USB fast charging This model supports an independent USB fast charging port with a built-in fast charging protocol chip and a maximum output power of up to 18W to provide fast charging for cell phones, PADs, charging pads and other devices with fast charging protocol. The output power is automatically adjusted according to the fast charging protocol supported by the device being charged, and will be output at standard 5V when used by devices that do not have fast charging capabilities. Regulated output This power supply can accurately set the voltage and current you need, and it can automatically calculate the output power based on the output voltage and current, while displaying the voltage, current, and calculated power on the screen. 110V/220V Automatic Matching Different from the power supply with ordinary single voltage input type. This power supply has 110V/220V dual voltage input, which allows you to use in different country locations. The bench power supply requires no manual configuration. It will automatically select the appropriate input voltage setting. What you get You will get.

However, with new STEM Solar Energy Monitoring IoT boards, which I am designing, it is sometimes required to replicate a Solar Panel string, using a controlled variable DC supply in the lab. For this a ~40 to 120V DC power supply is required. Purchased this adjustable 0-120V DC Power Supply and upon its fast next day delivery, it has been pressed into service. Works very well. Output is accurate and easy to change voltage and current limits. More importantly, the power supply has a mains ON/OFF plus a DC Output On/OFF. So you can easily set the required voltage and just turn on the output when needed. This is a safety must for High Voltage DC supplies and good to see this on the PSU. Have checked the DC output on the scope, put on a Solar Invertor and also into a DC-DC SMPS and it works perfectly - clean enough for my lab testing. Would recommend, if you need a high voltage DC power supply for some projects. You just need to ensure you have the right voltage set BEFORE turning the DC output on! ** IMPORTANT. 75-120V DC is Dangerous and can cause Electric Shock and Muscular Inhibition! Please RESPECT this Power Supply Output and be careful!! ** ## Features - High Precision and Small Size: The power supply adopts 4-digit LED display, voltage display 0.01V, current display 0.001A. voltage, current, power three windows display (0-120V/0-3A adjustable). Weighing only 2.47 pounds, the size (7.48 x 3.54 x 5.9 inches) is easy to carry. - Digital Adjustment: This power supply is encoder adjustment, it can be pre-set to the parameters you need and through the OUTPUT button to turn on or off the output of the power supply (when you trigger the OCP protection can press the OUTPUT button to lift the protection state) - USB Fast Charging Interface: the power supply is configured with 18W fast charging interface, supporting a variety of fast charging protocols. Automatically adapted to the fast charging protocol of the device being charged. The USB can save your workbench space and power your electronics. - CC/CV Automatic Switching: constant voltage and constant current values can be preset by coding knob, and automatically switch CC/CV state according to the load state. The product has OVP, OCP, SCP, temperature-controlled heat dissipation and other perfect protection mechanisms to effectively extend the service life of the product. - OCP Short Circuit Protection Function: press the CURRENT code switch for 3 seconds (can turn on or off the short circuit protection alarm function). ocp enabled, when the external load short circuit or overcurrent power supply will stop output and sound an alarm (can effectively protect the tested products) you can get (power supply x 1, British standard AC power supply x 1, output crocodile clip load cable x 1, product User's Manual x1) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B11H2LJQ | | Amperage | 3 Amps | | Best Sellers Rank | 616 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 1 in Industrial Power Supply | | Brand | NANKADF | | Brand Name | NANKADF | | Colour | black | | Connector Types | USB, Crocodile Clip | | Connector type | USB, Crocodile Clip | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 117 Reviews | | Enclosure Material | PE_(Polyethylene), PLA_(Polylactic_Acid), PS_(Polystyrene) | | Form Factor | Benchtop | | Input Voltage | 115 Volts | | Input voltage | 115 Volts | | Item Weight | 1.54 Kilograms | | Item weight | 1.54 Kilograms | | Manufacturer | NANKADF | | Manufacturer Part Number | WPS-10H | | Material | PE_(Polyethylene), PLA_(Polylactic_Acid), PS_(Polystyrene) | | Maximum Power | 360 Watts | | Model Number | WPS1203H | | Output Current | 3 Amps | | Output Wattage | 360 Watts | | Specification Met | CE, RoHS | | UPC | 780279579758 | | Unit Count | 1.0 count | ## Product Details - **Brand:** NANKADF - **Colour:** black - **Connector type:** USB, Crocodile Clip - **Item weight:** 1.54 Kilograms - **Material:** PE_(Polyethylene), PLA_(Polylactic_Acid), PS_(Polystyrene) ## Images ![DC power supply (0-120V,0-3A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supplies, output on/off/encoder knob - Image 1](https://m.media-amazon.com/images/I/71atLaLbmiL.jpg) ![DC power supply (0-120V,0-3A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supplies, output on/off/encoder knob - Image 2](https://m.media-amazon.com/images/I/71hUx56HIrL.jpg) ![DC power supply (0-120V,0-3A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supplies, output on/off/encoder knob - Image 3](https://m.media-amazon.com/images/I/71OoLRyEJxL.jpg) ![DC power supply (0-120V,0-3A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supplies, output on/off/encoder knob - Image 4](https://m.media-amazon.com/images/I/7163QUKOQ-L.jpg) ![DC power supply (0-120V,0-3A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supplies, output on/off/encoder knob - Image 5](https://m.media-amazon.com/images/I/816aGdwZuJL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by N***M on 7 June 2026* Good quality ### ⭐⭐⭐⭐⭐ Electronics Bench 0-120V DC PSU - Perfik for Electronic Lab R&D projects *by D***. on 24 April 2023* As an Electronics Engineer, I have accumulated a vast range of test equipment over the years.
