Specification: Origin: Mainland China Type: Module Condition: New 1. Input Voltage Range: 3.5V-30V (must ensure that the output set voltage is higher than the input voltage) 2. Output Voltage Range: 4.0V-30V 3. Maximum Input Current: 5A (output current under rated conditions is calculated according to power conservation) 4.Uin*Iin*efficiency=Uout*Iout) 5. Continuous Operating Current: 3A (the ratio of output voltage and input voltage under good ventilation and heat dissipation conditions can not be greater than 3) Product Size: 53.00x38.00x12.00mm/2.09x1.5x0.47inch Note: When you test if the output voltage is not higher than the input voltage, please adjust the potentiometer clockwise, the output voltage will rise, please do not adjust counterclockwise so that the module will be damaged or even damaged in the case of high input voltage! Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement.
