The display part of WWZMDiB adopts a more advanced voltmeter microprocessor, and the booster part adopts a booster controller imported from the United States. By using the on-resistance of the power MOSFET to save the current detection resistor, the efficiency is maximized, and the efficiency is as high as 96.4%. Imported high-power low-resistance MOS tube, large package, high current, high-efficiency Schottky, and ultra-wide and thick PCB traces are the guarantee of high-power, high-efficiency, and low-temperature rise. Ultra-wide voltage operation, when the input and output voltages are above 20V, the output power can be 128W. Long-life switching power supply high-frequency, high-capacity, low-resistance (low ESR) aluminum electrolytic capacitors make the output ripple lower. The chips used in the module are imported with original materials, and the performance is stable.

Added advantages:
1. Onboard LED working indicator, the working status is more intuitive.
2. One key to switch the digital tube on and off, one key to switch the measurement of input and output voltage. (The on-board voltage indicator "IN" lights up to display the input voltage, and "OUT" lights up to display the output voltage).
3. This product is launched, the voltage display value program self-correction function! There will be no problem with the voltmeter.

1. Performance parameters:
1.1. Input voltage: 3~35V DC (Note: If the input voltage is less than 4V, the on-board voltmeter will fail)
1.2. Input current: 9A (max)
1.3. Output voltage: 3.5~35V DC (this board is a booster board, the output voltage should be >= input voltage)
1.4. Output current: 6A (max)
1.5. Output power: 75W, (128W when the input and output voltages are greater than 20V)
1.6. Conversion efficiency: 96.7% (high)
1.7. Output ripple: 24mV (TYP)
1.8. On-board voltmeter range: 4~40V, error +-0.1V
1.9. Short circuit protection: yes (limited current 14A). Reminder: When connecting to a high-power load, the current limiting self-locking protection will occur due to the large inrush current at the beginning of the power-on. It is recommended to turn on the power first, and then connect to the load.
1.10. Input reverse connection protection: none (if necessary, please connect a high-current diode in series with the input).
1.11, length x width x height = 67*43*12MM (excluding copper pillars)

2.1 Double-key combination correction voltage method:
2.11 Step 1. Adjust the right button to make the "OUT" indicator light, and the voltmeter will display the output voltage; press and hold the right button for more than 2 seconds and then release, the voltmeter and the "OUT" indicator will flash synchronously, so you have entered the output voltage display calibration model.
2.12 Step 2. Short press the right button (at normal speed) once, the voltage value will increase by one unit of voltage value; short press the left button, the voltage value will decrease by one unit of voltage value; since the voltage value of one unit is less than 0.1 V, the small display of the voltmeter is 0.1V, so you need to press 1-5 times continuously to see that the voltmeter has changed by 0.1V. Specifically, the voltmeter will change by 0.1V by pressing the button several times in a row, depending on the current displayed voltage, the current display The higher the voltage, the fewer pressings.
2.13 Step 3. After adjusting the output voltage, press and hold the right button for more than 2S and then release it to exit the output voltage display calibration mode. All parameter settings are automatically saved after power-off.

2.2 Input voltage display calibration
2.21 Step 1. Adjust the right button to make the "IN" indicator light, and the voltmeter displays the input voltage; press and hold the right button for more than 2S and release it, the voltmeter and the "IN" indicator light flash simultaneously, so you have entered the input voltage display calibration model.
Steps 2 and 3 are the same as the output voltage display calibration method.

3. Scope of application:
3.1. DIY a regulated power supply, the input is 5V, and the output can be adjusted from 5-35V.
3.2. To supply power to your electronic equipment, you can set the output value according to your system voltage. For example, 3.7V lithium battery rises to 5V as a mobile power supply, and 7.4V or 12V rises 19 to power notebooks.
3.3. As a vehicle power supply, power supply for your notebook computer, PDA or various digital products.
