ITEM NAME:DC-DC Buck Converter Step-down Power Module 7-32V to 0.8-28V 12A 300W Ad EVI Descriptio n Description: Input voltage: 7-32V Output voltage: continuously adjustable (0.8-28V) Fixed output: any choice between 0.8-28V Output current: up to 12A Constant current range: 0.2-12A (adjustable) Turning lamp current: constant current value * (0.1), the lamp current is linked with the constant current value, for example, the constant current value is 3A, and the lamp current is set to 0.1 times of the constant current (0.1*3A=0.3A). When the current value is adjusted to 2A, the lamp current is 0.1 times of the constant current (0.1*2A=0.2A). The lowest voltage difference: 1V Output power: The maximum power is about 300W. If the power tube temperature exceeds 65 degrees, please add a fan. Conversion efficiency: up to about 95% Working frequency: 300KHZ Output ripple: 20M bandwidth Input 24V output 12V 5A ripple around 50mV (no noise) Operating temperature: industrial grade (-40 Â ° C to +85 Â ° C) Load regulation rate: Â ±1% (constant voltage) Voltage regulation rate: Â ±1% Constant current accuracy and temperature: In actual test, the temperature on the module changes from 25 degrees to 60 degrees, and the constant current value changes less than 5% (constant current value 5A) Dynamic response speed: 5% 200uS Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) close to the input potentiometer for voltage regulation (CV), near the output potentiometer for current regulation (CC) Indicator light: Two-color indicator light, the indicator light is red during charging, the charging completion indicator is green (no load is green) The indicator without constant current is red. Output short circuit protection: yes, constant current Input reverse connection protection: none Output prevents backflow: none Wiring method: terminal block Battery charging How to use: 1. Determine the float voltage and charge current of the rechargeable battery you need, t.Output power: The maximum power is about 300W. Output current: up to 12A. Input 24V output 12V 5A ripple around 50mV (no noise). Constant current accuracy and temperature: In actual test, the temperature on the module changes from 25 degrees to 60 degrees, and the constant current value changes less than 5% (constant current value 5A).
