Features: The module adopts synchronous rectification technology, which greatly reduces rectification loss at the output terminal, thereby improving conversion efficiency and reducing heating of the power supply itself. Short circuit protection, input reverse polarity protection. Includes aluminum shell for fast heat dissipation. Specification: Rectification mode: synchronous rectification Type: non isolated buck module (BUCK) Output current: 15A (max), ≤10A(continuous) (related to input and output pressure difference, temperature, etc) Output power: 100W(good ventilation and natural heat dissipation), 200W(enhance heat dissipation) Working temperature: -10~+85℃ Operating frequency: 180KHz Short circuit protection: Yes Reverse polarity protection: Yes Wiring: large current terminal, free welding, IN+, IN-, OUT+, OUT- Aluminum shell size: 70*38*31mm / 2.8*1.5*1.2in Weight: Approx. 83g Package list: 1 x Adjustable Step Down Module 1 x Aluminum Shell Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. .
