Description
- 1. Module has IN/OUT, ON/OFF two buttons: IN/OUT button switches input voltage and output voltage display, long press can switch output current output power display; ON/OFF button control output ON or OFF, long press can Set the default output state of the next power-on to be ON or OFF. 3.2.CC is the current setting potentiometer, clockwise rotation, can increase the set current, when the load current reaches the set current, enter the constant current state, the CC constant current indicator
- 2. How to use: 4.1. Use as a normal buck module with overcurrent protection Adjust the CV constant voltage device so that the output voltage reaches the voltage you want. Firstly rotate the CC current adjustment potentiometer counterclockwise for more than 10 turns, then use the multimeter 10A or 20A current file to measure the output short-circuit current , adjust the CC constant current potential clockwise. The output curre
- 3. Use as a battery charger Modules without constant current function cannot be used to charge the battery. Because the voltage difference between the battery and the charger that consumes electricity is too large, the charging current is too large, causing damage to the battery. Therefore, the battery should be used at the beginning. Stream charging, when the charging reaches a certain level, it automatically switches back to constant voltage charging. Determine the float voltage and ch
- 4. Use as a high power LED constant current drive module Determine the operating current and operating voltage that you need to drive the LEDs; Under no-load conditions, the multimeter measures the output voltage, and adjusts the constant voltage position device to make the output voltage reach the LED working voltage; Firstly rotate the CC current adjustment potentiometer counterclockwise for more than 10 turns, then use the multimeter 10A or 20A current file to measure the out
- 5. Note: 5.1. Module input IN-disable and output OUT-short, otherwise the constant current function will be invalid. 5.2. Please ensure that the power of the power supply is greater than the power required by the output load. When the module is hot, please reduce the power usage!
