5A Constant Current LED Driver Module Battery Charging Voltage DC-DC 5-32V to 0.8-30V Power Supply Module for Arduino The module uses high quality imported chips with high efficiency (95% in Z) and low heat generation. Z can reach 5A current, and at the same time, YUAN installs TI's op amp to control the output current, which makes the overall output very stable. This module uses Sanyo low ESR filter capacitor equipped from YUAN, which can make the ripple voltage as low as 50mV! This module uses machine patch and reflow soldering. At the same time, each module undergoes a two-hour aging test before shipment to ensure high reliability. This module is an adjustable buck module. The output voltage can be changed by adjusting the blue adjustable resistor on the module. The input and output differential voltage is 1V and Z can provide 0.8V output. The inputs IN- (negative input), IN+ (positive input), OUT- (negative output) and OUT + (output positive) marked on the module must be connected correctly. Otherwise, the module may be damaged. Module properties: Non-Isolated Buck Module Rectification: Non-synchronous Rectification Input Voltage: 5V-32V Output voltage: 0.8V-30V Output current: adjustable Z Wide 5A Conversion efficiency: 95% (High Z) Switching Frequency: 300KHz Output ripple: 20m bandwidth (50mV) Load regulation: 0.5% Voltage regulation rate: 2.5%Operating temperature: -40C to +85CSize: 51*26.3*14 (Length*Width*Height)(mm)Battery charging How to use:1. Make sure you need charging float voltage and battery charging current, module input voltage.2. Adjust the constant voltage leveler to adjust the output voltage to around 5V.3. Measure the output short-circuit current with the 10A multimeter current meter, and adjust the constant current potentiometer to make the output current reach the predetermined load current value.4. By default, the current of the charging lamp in turn is 0.1 times the charging current (constant current value).5. Adjust the constant voltage leveler so that the output voltage reaches the float voltage.6. Connect the battery and try to charge. (Steps 1, 2, 3, 4, and 5 are for module entry. The output is empty and the battery is not connected.)Package Included:1 x 5A Constant Current Power Supply Control Module DC-DC 5-32V to 0.8-30V Battery Charging Voltage for Arduino ModuleNote: The data are all manual measurement, please allow 1-3cm error, due to the light and display difference, there will be some color difference, depending on the object physical received.
