Applications:
 
This module can be used in the input voltage is higher than the output voltage of the buck area, such as batteries, power transformers, DIY adjustable power supply, 24V car pen the power supply, industrial equipment buck, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V and so on.
 
Features:
 
With a voltmeter display, the voltmeter error ± 0.1V, range 4 ~ 40V. (Note: the input voltage is less than 4V, onboard voltage meter does not work does not show)
 
Large volume 5 * 5 Touch the key switch to measure the input or output voltage, and the indicator shows which terminal voltage is being measured. The initial power-on default digital display shows the input voltage and the input indicator is ON; touching the button, the digital display shows the output voltage, and the output indicator OUT is on. And keep the final setting, even if the power is turned on again
 
The voltmeter can be turned off, long press the switch for more than 1 second and less than 4 seconds, let go can be closed. After the voltage meter is turned off, simply press the switch, you can open the voltmeter.
 
Input and output voltage measurement error quasi-function, long press switch for more than 4 seconds, let go after the voltage measurement error into the quasi-function, then IN light (calibration input), digital tube flashing display positive value (factory parameter is 0.0) , This time short press the button to change the value (range of -0.5 to 0.5, the unit is V), positive sign that up alignment, negative means down calibration. Adjust the input after the more accurate value, press the button for more than 2 seconds, let go after the input error calibration, then OUT light (calibration output), and display the output of the calibration value, adjust the method and input the same, After the output of the more accurate value, long press the button for more than 2 seconds, after the release of the set value and return to the normal display voltage, set the correct value immediately and power loss is not lost. (With this feature, you can meet your higher accuracy requirements)
 
5. With terminal blocks, no soldering iron can also be used easily, and retain the wire connection point
 
(The input voltage must be higher than the output voltage of more than 1v)
 
6. With 150KHz internal oscillation frequency, belonging to the second generation switching voltage regulator, low power consumption, high efficiency
 
7. Input with diode protection, reverse will not burn the module
 
8. With overheating protection and short circuit protection (more than 15W please strengthen the heat)
Input voltage: 2.5V ~ 40V
Output voltage: 1.25V ~ 37V (adjustable)
Output current: 3A (max)
Conversion efficiency: 92% (highest)
Output ripple: <30mV
Switching frequency: 150KHz
Operating temperature: -45 ~ +85
 
Precautions:
The maximum output current can be as high as 3A, the recommended operating current in 2A or so, more than 2A plus heat sink
When the output voltage can not be adjusted, always equal to the input voltage of this problem, please counterclockwise rotation of the potentiometer 10 laps above, and then use the module can be normal adjustment of the voltage. Because the buck module is factory, the default output voltage is about 20V.
