5.76 6.97 VAT included
Rated 5/5 (1 Vote)
Model: BSC-CCB35V
- Operating voltage: 4 to 38V (At least 1.5V higher than the output)
- Output: 1.25 to 35V
- Size: 60 x 37 x18 mm
- Max current: 5A
- Uses the DC-DC converter XL4015

Press the button (right) to switch voltage to measure, between the input voltage and output voltage. There are 2 LEDs to indicate which voltage is measuring by the voltage meter. And it has a Power indicator LED (GREEN). You can change the input or output voltage measurement by Short press the button on the right side ,and also can close the voltage meter by pressing the button on the left side.

This module can be also calibrated manually as following method:
1. Power up the module with a stable and accurate power supply , such as a 5V power supply, then shot press the button on the right side to select which one do you need to adjust (input or output), and long pressing (press time > 2S) the button(right) makes the module enter the calibration model, after releasing the button, the related LED would blink to indicate which voltage is now calibrating, and the numeric display blinks the correction value.
2. Short press the button to change the correction value, Short press the button on the right side, voltage increases one unit, Short press the button on the left side, voltage reduce one unit, for example, if your power supply is 5V, but the result of voltage meter is 4.8, you need to set the value to 5V.
3. Long press button on the right side(press time aprox. 2S), to store the voltage correction value.
4. Calibrate the output voltage in the same way above; The correction value will be stored in nonvolatile memory.
Tips: You can contrarotate to the potentiometer more than 10 circles at first. Because of the default output voltage of this module is 20V.
