The step down regulator can apply to constant output current. - With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. The efficiency can be up to 95%,(measured at 20A, converting 24V to 12V). - It is designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. Wiring is convenient with these large current 30A screw terminals. - The buck module has 2 heat sink that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current. - Application: Motors, audio, monitor, LED car display, air conditioner, fans, solar energy, photovoltaic energy, DVD, LED lights, pumps, industrial equipment appliances, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B51D7TWR | | Brand | iHaospace | | Current Rating | 20 Amps | | Customer Reviews | 3.6 3.6 out of 5 stars (28) | | Item Dimensions D x W x H | 2.7D x 5.3W x 2.7H centimetres | | Item Weight | 0.17 Kilograms | | Manufacturer | iHaospace | | Manufacturer Part Number | 300W | | Minimum Frequency | 50 Hz | | Model Number | 300W | | Power Source | Solar Powered | | Product Warranty | 1 Months | | Specification Met | Ma | ## Product Details - **Brand:** iHaospace - **Current rating:** 20 Amps - **Power source:** Solar Powered - **Product dimensions:** 2.7D x 5.3W x 2.7H centimetres - **Specification met:** Ma ## Images ![2 Pcs Constant Current CC CV Buck Converter Module DC 6-40V to 1.2-36V 20A 300W Adjustable Step Down Voltage Regulator Power Supply Module with Short Circuit Protection Function - Image 1](https://m.media-amazon.com/images/I/71cJ1wFOb9L.jpg) ![2 Pcs Constant Current CC CV Buck Converter Module DC 6-40V to 1.2-36V 20A 300W Adjustable Step Down Voltage Regulator Power Supply Module with Short Circuit Protection Function - Image 2](https://m.media-amazon.com/images/I/61BFAWvzAVL.jpg) ![2 Pcs Constant Current CC CV Buck Converter Module DC 6-40V to 1.2-36V 20A 300W Adjustable Step Down Voltage Regulator Power Supply Module with Short Circuit Protection Function - Image 3](https://m.media-amazon.com/images/I/61biurvp7VL.jpg) ![2 Pcs Constant Current CC CV Buck Converter Module DC 6-40V to 1.2-36V 20A 300W Adjustable Step Down Voltage Regulator Power Supply Module with Short Circuit Protection Function - Image 4](https://m.media-amazon.com/images/I/61NhaCoYlLL.jpg) ![2 Pcs Constant Current CC CV Buck Converter Module DC 6-40V to 1.2-36V 20A 300W Adjustable Step Down Voltage Regulator Power Supply Module with Short Circuit Protection Function - Image 5](https://m.media-amazon.com/images/I/61pLp17pAdS.jpg) --- ## 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.pl/products/505297887-2-pcs-constant-current-cc-cv-buck-converter-module-dc](https://www.desertcart.pl/products/505297887-2-pcs-constant-current-cc-cv-buck-converter-module-dc) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-09*
