5.Switch Campus Broadcasting Band: Keep press V+ and V- before power ON and then turn ON work power switch. It means enable Campus Broadcasting Band if display C1 on LCD. It means disable Campus Broadcasting Band if display C0 on LCD.Available after restart.

6.Enable backlight mode: Keep press P+ and P- before power ON and then turn ON work power switch. It means keep backlight ON if display B1 on LCD. It means the backlight will turn OFF after 20second if display B0 on LCD(This is the power saving mode). Available after restart.

7.It can output audio from speaker and earphone jack. The speaker of the module does not work when the earphone is connected.

DC-DC Boost Power Supply Module DC 3V-35V to DC 3.5V-50V 6A 100W High Power Digital Display

Product Introduction:

It is a booster board, the output voltage is greater than the input voltage. When the output voltage is less than 4V, the onboard voltmeter will not work.

Feature:

1.It has a digital display to display voltage.

2.Its conversion efficiency is high.

3.It has an output voltage potentiometer to adjust the voltage in time.

4.It has a display switch button to switch between input voltage display and output voltage display.

Parameter:

1.Product Name:Boost Module

2.Input Voltage:DC 3.3~35V

3.Input Current:9A(Max)

4.Output Voltage:DC 3.5~50V

5.Output Current:6A(Max)

6.Output Power:100W (input voltage greater than 12V can reach the maximum output of 100W)

7.Conversion Efficiency:96%(Max)

8.Output Ripple:40mV(TYP)

9.Range of Onboard Voltmeter:3~55V

10.Work Temperature:-25℃~85℃

11.Work Humidity:5%~95%RH

12.Size:68*42*18mm

Instructions for Use:

1.The voltmeter can be turned off.Press and hold the switch for 4 seconds,and then it can be turned off by letting go.

2.Input and output voltage measurement error calibration function,long press the switch for more than 4 seconds,after letting go,it will enter the voltage measurement error calibration function.

3.The digital tube flashes to display the voltage calibration ratio value (range -5V~5V).At this time,short press the button to change this value (cycle between -5V~5V).

4.When the voltage value displayed by the voltmeter is too high,lower the reference value (adjust to a negative number).

5.When the voltage value displayed by the voltmeter is low,increase the reference value (adjust to a positive number).

6.After adjusting to the reference value you want,press and hold the button for more than 2 seconds. After letting go,save the set value and return to the normal display voltage.The set correction value will take effect immediately and will not be lost after power failure.

Thanks for your time! We will have more new arrivals soon!
