Zoom
Description
Brand: FBHDZVV
Module nature: non-isolated step-down module
Rectification method: asynchronous rectification
Input voltage: 7V-35V
Output voltage: 1.25V-30V
Output current: adjustable 3A
Conversion efficiency: 92%
Switching frequency: 150KHz
Output ripple: 50mV
Battery charging How to use:
1. Determine the float voltage and charging current of the battery you need to recharge, and the input voltage of the module
2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V
3. Use a multimeter with a 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value
4. The default charging current of the turning light is 0.1 times the charging current (constant current value). If you need to adjust it, please adjust the turning light current potentiometer; (generally no need to adjust)
5. Adjust the constant voltage potentiometer to make the output voltage reach the floating voltage
6. Connect the battery and try charging.
(Steps 1, 2, 3, 4, and 5 connect the module input to power, and the output is unloaded and does not connect to the battery.)

LED constant current driver usage:
1. Determine the operating current and maximum operating voltage you need to drive the LED
2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V
3. Use a multimeter with a 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current
4. Adjust the constant voltage potentiometer to make the output voltage reach the LED working voltage
5. Connect the LED and test the machine
(Steps 1, 2, 3, and 4 connect the module input to the power supply, and the output is unloaded and does not connect to the LED light.)
