Voltage Boost Circuit with 6A Display

Boost circuit with 6A display and maximum efficiency up to 96.4%. Imported MOS, low resistance, high power, high current, high efficiency, thick PCB. Wide voltage operation up to 35V. This is a user-friendly, cost-saving boost module. SPECIFICATIONS
Input voltage: 3 ~ 35V DC (input voltage less than 4V, the on-board voltmeter display is not accurate)
Input current: 9A (maximum)
Output voltage: 3.5 ~ 35V DC (output voltage is always greater than or equal to input voltage)
Output current: 6A (maximum)
Conversion efficiency: 96.7% (highest)
On-board voltmeter range: 4 ~ 40V, error + -0.1V
Short circuit protection: available (current limit of 14A). Advice: When accessing high power loads, due to the high current increase, use self-locking current limit protection. Turn on the power first and then connect to the load.
Reverse input connection protection: not available
New advantages:
LED indicator light for more intuitive working status.
One button to switch between input and output voltage measurement. (The on-board electronic voltmeter indicator light IN lights up for input voltage and the OUT indicator light lights up for output voltage).
This product introduces the function of self-calibration of displayed voltage value.
Dual-key voltage calibration method: Calibrate the output voltage display Step 1. Adjust the right button to make the OUT indicator light up. At this time, the voltmeter displays the output voltage. Press and hold the right button for more than 2S and release it simultaneously. The voltmeter and the OUT indicator will flash simultaneously, allowing you to enter the output voltage display calibration mode.
Step 2, press the right button once quickly (normal speed), the voltage value will increase by one unit value, press the left button, the voltage value will decrease by one unit value, because the voltage value is less than 0.1V, the minimum display of the voltmeter is 0.1V, so you need to continue to push 1-5 times to see the changes in 0.1V increments.
Step 3: After adjusting the output voltage, press and hold the right button for 2S or more and release it to exit the output voltage display calibration mode. All parameter settings are automatically powered off.
Calibrate the input voltage display
Step 1. Adjust the right button to make the IN indicator light up. At this time, the voltmeter displays the input voltage. Press and hold the right button for more than 2S and release it simultaneously. The voltmeter and the IN indicator will flash simultaneously, allowing you to enter the input voltage display calibration mode.
Steps 2 and 3 correspond to the method of calibrating the output voltage display. This product has been tested more than three times before….
