Parameters: Input voltage range: DC 5.3-32V (limit 35V; the lowest input 4V can achieve buck, but less than 5.3V input voltage, current measurement is inaccurate) Output voltage range: DC 1.2-32V (must ensure that the input voltage is higher than the output voltage, the minimum voltage difference is 0.8V) Output current: 8A for long-term stable work, strengthen the heat dissipation can reach 12A Output power: natural cooling 120W (within 8A), enhance cooling can reach 160W Voltage display: resolution 0.05V, range 0-32V Current display: resolution 0.01A, range 0-12A Conversion efficiency: about 96% Working current: 25mA or so Soft start: Yes (high power with load module may fail to start) Input reverse connection protection: yes Output stop current from feeding back: none (if you charge the battery, first power the module then connect to the battery, and ensure that the battery voltage is lower than the output voltage) Short circuit protection: yes Dimension: 82x 52x 32mm Attentions: 1. Module input IN- cannot short circuit with output OUT-, otherwise constant current function will be invalid. 2. Please make sure that the power of the power supply is greater than the power required by the output load. Please reduce the power when the module is extremely hot.
