Adjustable 4-40V DC/DC step-down voltage regulator, high-efficiency converter module, stable output, wide input voltage range

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 device 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. The current clamp eliminates the need for a soldering iron, and the connection point is preserved. 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 adjustable output voltage range is between 1.25 V and 37 V and is continuously adjustable (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. Technical Specifications: Features: With voltmeter display, measurement error ±0.1 V, measuring range 0–40 V. The input and output voltage measurement can be switched by pressing the button. The indicator light shows the measured voltage and saves the last setting even after switching off and on again. The voltmeter can be switched off by holding the switch for more than 1 second and less than 4 seconds. With terminal block, no soldering iron is required; the wire connection points are preserved. 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) illuminates and the digital display flashes to show the correction value (factory setting: 0.0). Press the button to change this value (value range: -0.5 to 0.5, unit: V). A positive value indicates an increase, a negative value a decrease. After setting the reference value for the input voltage range, press and hold the button for more than 2 seconds, then release it. The output indicator (calibration output) illuminates and displays the output calibration value. The setting method is the same as for the input. After setting the output reference value, press and hold the button for more than 2 seconds. After releasing the button, the set value is saved and the display returns to normal. The adjusted correction value takes effect immediately and there is no power interruption.
Note:
The built-in voltmeter will not function and will not display any readings if the input voltage is below 4 V.
