Description

XL6009 LED display Boost Module DC-DC 4A Power Module    Input voltage: 4.5V 32VThe output voltage: 5V~ 35V (adjustable)Output current: 4A (max)Conversion efficiency:    92% (highest)Output ripple: 30mVOn-off level: 400KHzOperating temperature: -45°C +85°CProduct Size: 66*36*14MMFeatures:    1. With voltmeter display, voltmeter error  ±0.1V, range 5 ~ 35V. (Note: the input voltage is lower than 4.5V, the on-board voltmeter does not work and does not display)    2. Large size 5*5 touch the button to switch the measurement input or output voltage, and there is an indicator light to show which terminal voltage is being measured. The first boot, the default digital tube displays the input voltage, and the input indicator IN is on; touch the button, the digital tube displays the output voltage, and the output indicator OUT is on. And keep the settings, even after power off and on again    3. The voltmeter can be turned off, press and hold the switch for more than 1 second and less than 4 seconds, and release it to turn off. After the voltmeter is turned off, just short press the switch to turn on the voltmeter.    4. Input and output voltage measurement error calibration function, press and hold the switch for more than 4 seconds, and then enter the voltage measurement error calibration function after letting go. At this time, the IN light is on (calibration input terminal), and the digital tube flashes to display the correct value (the factory parameter is 0.0), at this time, short press the button to change this value (the value range is -0.5 to 0.5, the unit is V), a positive number means upward calibration, and a negative number means downward calibration. After adjusting the calibration value of the input end, press and hold the button for more than 2 seconds, and then let go to the error calibration of the output end. At this time, the OUT light is on (calibrating the output end), and the calibration value of the output end is displayed. The adjustment method is the same as that of the input end. After the calibration value of the output terminal, press and hold the button for more than 2 seconds. After letting go, the set value will be saved and the voltage will return to normal display. The set calibration value will take effect immediately and will not be lost after power failure. (With this function, you can meet your higher precision requirements)    5. With terminals, it is easy to use without a soldering iron, and the soldering wire connection points are reserved    (The input voltage must be more than 1v higher than the output voltage)    6. The output current can be as high as 3A, the recommended working current is about 2A, if it exceeds 2A, add a heat sink    7. The internal oscillation frequency of 400KHz is adopted, which belongs to the second generation switching voltage regulator, with low power consumption and high efficiency.    Precautions:    1. When the power usage exceeds 20W, it is recommended to add heat sinks to enhance heat dissipation;    2. Some customers report that the output voltage of the module cannot be adjusted and is always equal to the input voltage. When you encounter this kind of problem, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally.    Applications:         This module can be used in the boost field where the output voltage is higher than the input voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V car notebook power supplies, industrial equipment step-down, 9 to 12V, 12V to 18V, 18V to 24V, etc.
