LM2596 DC-DC 3A Adjustable Step-down Module LM2596 Constant Current Voltage Regulator High Efficiency Low Heat
Product parameters:
1. Module nature: Non isolated voltage reducing module
2. Rectification method: asynchronous rectification
3. Input voltage: DC7V-35V
4. Output voltage: DC1.25V-30V
5. Output current: maximum 3A (adjustable)
6. Conversion efficiency: 92% (highest)
instructions：
This module is an adjustable voltage reduction module that can change the output voltage by adjusting the voltage potentiometer. The input and output voltage difference is 2V. The IN - (input negative), IN+(input positive), OUT - (output negative), and OUT+(output positive) marked on the module must be connected correctly, otherwise it may cause damage to the module.
1. Battery charging usage method:
① Determine the float charging voltage and charging current of the rechargeable battery you need, as well as the input voltage of the module;
② Adjust the constant voltage potentiometer to adjust the output voltage to around 5V;
③ Measure the output short-circuit current with a multimeter in 10A current mode, and adjust the constant current potentiometer to achieve the predetermined charging current value
④ The default shipment of the charging to lamp power supply is 0.1 times the charging current (constant current value). If adjustment is needed, please adjust the lamp current potentiometer; (Usually does not require adjustment)
⑤ Adjust the constant voltage potentiometer to make the output voltage reach the float charging voltage;
⑥ Connect the battery and try charging.
(Steps 1, 2, 3, 4, and 5 are to connect the module input to the power supply and the output to no load without connecting the battery)
2. Usage of LED constant current driver:
① Determine the operating current and maximum operating voltage required to drive the LED;
② Adjust the constant voltage potentiometer to adjust the output voltage to around 5V.
③ Measure the output short-circuit current with a multimeter in 10A current mode, and adjust the constant current potentiometer to achieve the predetermined LED operating current;
④ Adjust the constant voltage potentiometer to make the output voltage reach the working voltage of the LED;
⑤ Connect the LED and test the machine.
(Steps 1, 2, 3, and 4 are to connect the module input to the power supply, and the output is unloaded without connecting the LED light)
