Product Brief Introduction

The input voltage is DC 3V~32V (boost below 5V works normally, but the digital tube does not work), and the optimal operating voltage range is DC 5~32V;

Output voltage DC 5V~35V;

Built in 4A high-efficiency MOSFET switch, achieving a maximum efficiency of 94;

The ultra-high switching frequency of 400KHZ can achieve very good results with small capacity filtering capacitors, with smaller ripple and volume.

Equipped with input/output indicator lights

Equipped with a voltmeter display and calibratable. We have adopted a more advanced voltage microprocessor, with a voltmeter error of ± 0.05V and a range of 0-35V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)

Touch the button to switch between measuring input or output voltage, and there is an indicator light to display which voltage is being measured, and save the settings, even if the power is turned off and restarted.

The voltmeter can be turned off, and when it is not needed to display, simply touch the right button for more than 3 seconds to easily achieve it (the input and output indicator lights will be turned off at the same time).

With wiring terminals, it can be easily used without a soldering iron, and the soldering wire connection points are retained.

Equipped with overheat protection and short circuit protection functions

Product Parameter

Module nature: non isolated boost (BOOST)

Rectification method: asynchronous rectification

Input current: 4A (maximum), unloaded 18mA (5V input, 8V output, unloaded less than 18mA). The higher the voltage, the greater the no-load current

Conversion efficiency:<94 (the greater the pressure difference, the lower the efficiency)

Switching frequency: 400KHz

Output ripple: 50mV (the higher the voltage, the greater the current, and the larger the ripple)

Product Note

1. Pay attention to wiring according to the diagram and do not make mistakes.

2. This document only represents the product parameters at the time of editing, and any changes in the future will not be notified separately.

3. This module is a boost module, and the output voltage will not be less than the input voltage.

Manual calibration method for onboard voltmeter:

When the onboard voltmeter displays the output voltage, press and hold the button on the right side for 2 seconds before releasing it. The voltmeter and output voltage indicator light "OUT" will flash synchronously, entering the output voltage adjustment mode; Similarly, when the voltmeter displays the input voltage, press and hold the button on the right side for 2 seconds and then release it. The voltmeter and input voltage indicator light "IN" will flash synchronously, entering the input voltage adjustment mode; After entering the voltage adjustment mode, there is a range adjustment of -5~5, and each press of the button changes one unit (equivalent to a range adjustment of 0~0.3V, and each press of the button changes about 0.025V voltage); Press and hold the right button for more than 4 seconds to turn off the digital display.

After the voltage adjustment is completed, press and hold the button on the right side for 2 seconds and then release it to exit the voltage calibration mode. All parameter settings will automatically power off and save.

3. Note: With this adjustment method, you only need to calibrate once to obtain accurate voltage values across the entire voltage range. This function is designed to meet your higher precision requirements, so please feel free to use it.
