Featuring advanced software protections and enhanced cooling, it ensures safe, precise, and reliable power regulation for professional and hobbyist applications alike. ## Description Note: After the product triggers the protection mechanism, the output will automatically turn off, the LCD screen will display the protection code, and press any key to exit the protection interface ## Features - Product Highlights one: ① LCD can display input/output voltage, output current/output power/output capacity/output time; ② Digital control adjustment, accurate and fast, step-down output, output voltage 0-50.00V can be adjusted arbitrarily, limited current 0-20.00A can be adjusted arbitrarily; ③ The output terminal will not burn when it is poured backward; ④ The module can be set to be turned on/off by default; - Product Highlights two: ⑤ Has a variety of software protection mechanisms, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output will be automatically turned off; ⑥ Using synchronous rectification technology, high conversion efficiency: more than 90% efficiency; ⑦ Enlarge the heat sink and install a fan to enhance heat dissipation. - Soft start:There are protection mechanisms: ①Input under-voltage protection (5.8-50V adjustable, default 5.8V) ②Output overvoltage protection (0-51.00V adjustable, default 51V) ③Output overcurrent protection (0-20.00A adjustable, default 20.10A) ④Timeout protection (0-100h adjustable, default off) ⑤Overcapacity protection (0-999.9Ah adjustable, default off) - This product is a digitally controlled adjustable step-down module. The LCD can display parameters such as input, output voltage, output current, and power, and the output voltage and current can be adjusted arbitrarily. The module also has a variety of software protection mechanisms. When the parameter exceeds the protection reading value, the output will be automatically turned off, making the use more worry-free. - Note: After the product triggers the protection mechanism, the output will automatically turn off, the LCD screen will display the protection code, and press any key to exit the protection interface ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0B38GYF74 | | Best Sellers Rank | #430,903 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #1,973 in Power Converters | | Brand | EC Buying | | Color | gray | | Customer Reviews | 4.3 4.3 out of 5 stars (76) 4.3 out of 5 stars | | Input Voltage | 6 volts | | Item Dimensions | 0.59 inches | | Item Type Name | power-converters | | Item Weight | 220 g | | Manufacturer | EC Buying | | Mfr Part Number | G34 | | Model Number | WZ5012L | | Number Of Items | 1 | | Number Of Outlets | 1 | | Output Voltage | 50 volts | | Plug Type | Type B | | Warranty Description | no | ## Product Details - **Brand:** EC Buying - **Color:** gray - **Input Voltage:** 6 volts - **Item Weight:** 220 g - **Item dimensions L x W x H:** 0.59 inches ## Images ![EC Buying CNC Buck Adjustable Power Supply Module, Adjustable Buck Converter ... - Image 1](https://m.media-amazon.com/images/I/61pcrBl-+vL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A well-designed buck converter *by on Reviewed in the United States June 24, 2025* Works as advertised and more. The conversion efficiency is quite high and the mosfets stay quite cool under load. Absolutely worth the price. I am using mine in a homemade power station, with a peak battery voltage of 50.4 V and an output of 12.4 V. The amp-hour measurement function is especially helpful. Overall this is a great product and seems quite well designed. ### ⭐⭐⭐⭐⭐ Ebike battery to laptop charger! *by on Reviewed in the United States January 14, 2023* This thing is great! I'm using it to convert a 36 volt e-bike battery down to 19.5 volts at 10 amps to directly charge my laptop via the DC port. So far it works absolutely wonders! It barely gets hot, the fan kicks on minimally - this may be because the voltage I'm converting is 36 only to 19.5 not a huge difference.Either way I'm blown away by the performance to cost ratio.For those of you also looking to make a high WHr DIY portable power banks to escape the remote life home office every now and then this buck converter is critical. Outlet anxiety is a thing of the past lol. Buy it you won't regret it, and if you do Amazon return policy is great 🤣 ### ⭐⭐⭐⭐⭐ It will do everything you need. DONT HOOK IT UP BACKWARDS. *by on Reviewed in the United States July 25, 2023* I use mine for controlled power supply into various dc things, works great. The UI is a little clunky but functional enough. I had a mishap and connected it backwards, fried the input diode and the input 20a smd fuse. Waiting on the new parts(ordered separately) to see if it's still alive. Will report backUpdate(5aug23)Parts finally arrived, ss10100 smd diode and the smd 20a fuses. Replaced both with little hassle and it revived! Intent now being ill be integrating this into a different build to provide local power that's usable at the voltages I need. Took a big hit and still runs ## Frequently Bought Together - EC Buying CNC Buck Adjustable Power Supply Module, Adjustable Buck Converter 50V 20A 1000W Voltage and Ammeter DC Voltage Regulator, LCD Display/DC Converter/DC CNC Power Supply/DC Converter Gray - Otdorpatio 2Packs Junction Box IP65 Waterproof ABS Plastic Electrical Project Case Power Junction Boxes, Project Box with Fixed Ear Black 3.94x2.68x1.97 inch(100x 68 x50 mm) --- ## 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.bo/products/455365847-ec-buying-cnc-buck-adjustable-power-supply-module-adjustable-buck](https://www.desertcart.bo/products/455365847-ec-buying-cnc-buck-adjustable-power-supply-module-adjustable-buck) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-08-16*
