1. Item highlights: 1.1 LCD can display input/output voltage, output current/output power/output capacity/output time; 1.2. CNC adjustment, accurate and fast, can lower voltage, output voltage can be adjusted at will from , limit current 0-20.00a can be adjusted at will; 1.3. the output end is poured backward without burning; 1.4. The module can be set to open/close by default; 1.5. Multiple software protection mechanisms are available, and the protection threshold is adjustable.When the working parameters of the module exceed the protection threshold, the output will be automatically closed. 1.6. Using synchronous rectification technology, the conversion efficiency is high: the efficiency is more than 90%. 1.7. Increase heat sink, install fan, strengthen heat dissipation. 2.
