The module adopts a step rectification scheme with extremely high efficiency, with a maximum efficiency of up to 95% Output voltage and current are continuously adjustable The input voltage can reach up to 75V, the output voltage can reach up to 60V, and the maximum current is 25A (when the input is 75V). Module parameters: Module name: 600w step-down constant voltage constant current adjustable power module Module nature: non-isolated step-down module (BUCK) Input voltage: 12-75V Output voltage range: 2.5-60V (must meet the step-down conditions, IN input multiplied by 0.8) Output minimum voltage: 2.5V Output maximum voltage: approximately equal to input voltage x 0.8 (for example, if the input is 40V, 40V x 0.8 = 32V, the maximum output voltage is 32V.) Output constant current: 1-25A (continuous Adjustable,) Maximum output power: 600W (the working environment must be well ventilated) Maximum continuous working power: 500W (under ventilated environment) Maximum continuous working current: 25A (under ventilated environment) Cooling method: air cooling Input undervoltage protection: no Input overvoltage protection: no (overvoltage prohibited) Working temperature: -10-+65 ℃ Working frequency: 80KHz Conversion efficiency: up to 95% (efficiency is related to input and output voltage, current, and pressure difference) Short circuit protection: yes (constant current protection) Note:Due to different production batches, there are differences in the components of the product, but it does not affect the use.
