APKLVSR Step Down Converter Module, DC-DC Buck Converter Module for 4-40 V to 3.3-24 V, Power Supply Down Module Pack of 4
APKLVSR Step Down Converter Module, DC-DC Buck Converter Module for 4-40 V to 3.3-24 V, Power Supply Down Module Pack of 4
APKLVSR Step Down Converter Module, DC-DC Buck Converter Module for 4-40 V to 3.3-24 V, Power Supply Down Module Pack of 4
- LED digital voltmeter display: Step-down module with the voltmeter display, the voltmeter error is ±0.1 V and the range is between 4 and 40 V. Note: If the input voltage is lower than 4 V, the integrated voltmeter does not work and does not display anything.
- 【Input and Output】: The step down module is wide voltage measurement/input range: DC 2.5-40V; Output voltage: 1.25-37V infinitely adjustable.Output current: 0-3A.The maximum output current can be up to 3A, the recommended working current is approx. 2A, more than 2A plus heat sink
- High quality: high efficiency and low ripple with power indicator. It has current limiting, short circuit and over temperature protection. Even if the output is short circuited, the module will not be blown out and it is safer.
- Easy to use: the step down converter can be switched off, and the switch can be switched off by holding the switch for more than 1 second and less than 4 seconds. Once the voltmeter is off, simply press the switch to turn on the voltmeter.
- Wide range of applications: This DC-DC buck converter module can be used in the buck field where the input voltage is higher than the output voltage, used for booster voltage stabiliser power supply, DIY adjustable mobile power supply, booster charger.

Specifications:
Input voltage: DC 2.5 V - 40 V.
Output voltage: DC 1.25 V - 37 V (adjustable).
●Output Current: 3A (Max)
● Conversion efficiency: 88%
● Size (L x W x H): 61 x 34 x 12 mm.
Operating frequency: 150 kHz.
●Output power: 20W, please increase heat dissipation if it exceeds 15W
How to calibrate?
1. Short press the left "ON/OFF" button to turn on the digital tube voltmeter. Long press the left button (> 1 s, < 4 seconds) to turn off the digital tube voltmeter.
2. Long press the left button (>4 seconds) to start the self-calibration of the voltage measurement (calibration range: -0.5-0.5V, factory setting is 0.0).
The "IN" indicator lights up = the calibration of the input voltage measurement begins.
Then press the right button "Mode" for a long time (> 2 seconds), the indicator "OUT" lights up = the calibration of the output voltage measurement begins.
Tap the left/right button to decrease/increase one unit (since the voltage value of one unit is less than 0.1V,
You need to press the button 1-5 times in a row so that the voltmeter can change by 0.1V).
3. After calibration, long press the right button "Mode" (> 2 seconds) to maintain the set value (no loss in case of power failure) and return to normal voltage display.
Note: :
If the output voltage of the module cannot be adjusted and is always equal to the input voltage, turn the voltage adjustment knob counterclockwise more than 10 revolutions and then use the module to adjust the voltage normally. Because when the downward module leaves the factory, the standard output voltage is about 20V.
