Adjustable DC/DC converter module, 4-40V step-down voltage regulator

Product Information

1. Press the button to switch between input and output voltage measurement. The indicator light shows the measured voltage and saves the last setting, even if the voltmeter is switched off and on again.
2. The voltmeter can be switched off by holding the switch for more than 1 second and less than 4 seconds.
3. Thanks to the terminal block, no soldering iron is required and the wire connection remains intact. The input voltage is 4.0 to 40 V (the input voltage must be at least 1 V higher than the output voltage).
4. The output voltage range is continuously adjustable from 1.25 V to 37 V (the input voltage must be at least 1 V higher than the output voltage).
5. The maximum output current is 3 A, the typical stable operating current is 2 A.

Functions:
With voltmeter display, voltmeter error ± 0.1 V, measuring range 0 to 40 V.
Pressing the button switches between input and output voltage measurement; the indicator light shows the measured voltage and saves the last setting, even after the voltmeter is switched off and on again. The voltmeter can be switched off by holding the switch for more than 1 second and less than 4 seconds. Thanks to the terminal block, no soldering iron is required, and the wire connection points remain intact. The input voltage is 4.0 to 40 V (the input voltage must be at least 1 V higher than the output voltage). The output voltage range is continuously adjustable from 1.25 V to 37 V (the input voltage must be at least 1 V higher than the output voltage). The maximum output current is 3 A, the typical stable operating current is 2 A. With an internal oscillation frequency of 150 kHz, it belongs to the second generation of switching regulators and is characterized by low power consumption and high efficiency.

Operating instructions:
Input and output voltage measurement error calibration function: Press and hold the switch for more than 4 seconds. After activating the calibration function, the indicator light (calibration input) will illuminate and the digital display will flash to show the correction value (default value: 0.0). Press the button to change this value (range: -0.5 ~ 0.5 V). A positive value (A) indicates an increase, a negative value a decrease. After setting the final comparison value, press and hold the button for more than 2 seconds, then release it. The output indicator will light up (calibration output), and the output calibration value will be displayed. The setting method is the same as for the input. After setting the output comparison value, press and hold the button for more than 2 seconds. Releasing the button saves the set value, and the display returns to normal. The adjusted correction value is applied immediately without any loss of performance.
Note:
The built-in voltmeter will not function and will not display any readings if the input voltage is below 4 V.
