1. Input voltage: 3-35V DC (Note: if the input voltage is less than 4V, the onboard voltage meter fail) 2. Input current: 9A (max) 3. Output voltage: 3.5-35V DC (this board is a boost board, the output voltage must be equal input voltage) 4. Output current: 6A (max) 5. Output power: 75W, (when both input and output voltages are 20V, it can reach 128W) Conversion efficiency: 96.7% Output ripple: 24mV (TYP) Onboard voltage meter range: 4-40V, error +-0.1V Short circuit protection: Yes (limited current 14A). Warm reminder: When connecting to a high-power load, the current be limited and self-locked due to the large impact current at the beginning of the startup. It is recommended to start the machine first and then connect the load. Color: Blue Material: plastic Package Contents: 1 x DC-DC 100W boost module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
