Description

LED power indicator.

Module is easy to use, very intuitive.Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; Thevoltmeter can be turned off by another button.

Module using”12A one piece of high quality inductor”, input current can be reached at 7A, similar products on the market are used in ordinary 5A inductor, performance parameters vacuity, we must pay attention!

Special precision voltmeter can also be manually calibrated.

Performance parameters
1.Input voltage range：3-35VDC(Note: the input voltage is less than 4V, voltmeter failure)
2.Input current：7A
3.Output voltage range：3.5-35VDC(please to ensure that output voltage above on input voltage)
4.Output current: 6A (max)
5.Output power: 75W (when the input and output voltages greater than 16V up to 100W)
6.Conversion efficiency: 96% (max)
7.Voltmeter range: 4 to 40V, error ±0.1V
8.Short circuit protection: yes(limit current 14A). (Note: connected to high-power load, just switched on the impact of current very general meeting current limiting self-locking protection, it is recommended to be switched on firstly, and then access the load).
9.Input reverse polarity protection: None (if required, high current diode in series with the input)
10.L*W*H = 67*42*12mm
11.Weight:38g
application

1. DIY a regulated power supply, 5V input can be output 5-35V adjustable.

2. The power supply for your electronic equipment. For example, 3.7V lithium boost to 5V for mobile power; 7.4V or 12V boost to the laptop power supply to 19V.

3.As the vehicle power supply for your laptop, PDA or a variety of digital products supply.

Voltmeter manual calibration method

If you feel voltmeter accuracy to meet the requirements, you do not need to perform the following operations.

(1) Output voltage calibration steps

Step 1,adjust the right button so that “OUT” LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release,voltmeter and “OUT” LED flashes in synchronization so that you enter the output voltage calibration mode.

Step 2,press the right button (normal speed),the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press.

Step 3,press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save.

(2) Input voltage calibration steps

Step 1,adjust the right button so that “IN” LED lighted, the voltmeter shows the value of input voltage; press the right button for more than 2 seconds, release,voltmeter and “IN” LED flashes in synchronization so that you enter the input voltage calibration mode.

Steps 2 and 3, consistent with the output voltage calibration method.
