상품특징
20A 300W DC Step Down Buck Converter, Input Voltage: DC 6-40V, Output Voltage: DC 1. 2-35V, Adjustable constant voltage constant current for DIY stabilized voltage supply, vehicle power, mobile power, battery charging, LED driver etc.Output Current: 20A (max), Constant Current Range: 0. 2-20A ( continuously adjustable ), Transfer Efficiency: 96% (MAX)With two large heat sink, LED indicator, output short-circuit instantaneous protection, more stable and reliable to use.Adopting 75V / 80A large current dual MOS tube designed step-down board, large current 30A connection screw terminals, more convenient to install.Output voltage should be lower than input voltage, Recommended Minimum Voltage Difference: 3V. When there is a big difference between the input voltage and the output voltage, please reduce power and current.
상품설명
Feature: Module Name: 20A 300W DC Step Down Buck Converter Input Voltage: DC 6-40V, Optimum input voltage 10-40V Output Voltage: DC 1. 2-35V ( continuously adjustable ), Recommended below 32V for long time work Minimum Voltage Difference: 3V, output voltage should be lower than input voltage Output Current: 20A (max), Recommended below 15A for long time work Constant Current Range: 0. 2-20A ( continuously adjustable ) Transfer Efficiency: 96% (MAX) Output Ripple: About 50mV Switching Frequency: 150KHz Work Temperature: -40 degree to + 75 degree Celsius, please strengthen the heat dissipation or reduce the value if exceeds 65 degree. CV Potentiometer: Increase voltage clockwise, decrease voltage counterclockwise CC Potentiometer: Increase current clockwise, decrease current counterclockwise Output Short-circuit Protection: Yes, (Instantaneous protection) Constant Current (The current constant current value should not short-circuit for a long time) Output Anti-Perfusion: NO, For load with built-in electric or inductive negative load requires additional diodes Connection Mode: Terminals Module Size: 60x53x27mm/2. 36x2. 08x1. 06 inch Output voltage/current regulation method: 1. Adjust CV potentiometer according to your battery or LED, and set the output voltage to the value you need. 2. Turn the CC potentiometer clockwise for about 30 turns, set the output current to the minimum, connect the LED, and adjust the CC potentiometer to the current you need. If it is used for battery charging, after the battery is discharged, then connect to the output, and adjust CC potentiometer to the current you need. (the more residual battery power, the lower charging current). Package Include: 1pcs 20A 300W DC Step Down Constant Voltage Constant Current Buck Converter
