DC-DC Adjustable Step-down Power Module with Voltage Indicator 5A High Power 75W,Default NO5245

Features:

1. low ripple 5A high power high efficiency step-down module.

2. With power indicator.

3. On-board voltmeter, voltmeter can be self-calibrated, there will never be a problem with voltmeter inaccuracy.

4. With power indicator. 

5. With voltmeter display and voltmeter can be self-calibrated. A more advanced voltage microprocessor is used, the voltmeter error is ±0.05V, and the range is 0~40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)

6. Touches the button to switch the measurement input or output voltage, and the indicator light shows which voltage is being measured, and save the settings, even if it is powered off and then on.

7. The voltmeter can be turned off, and it can be easily achieved by tapping the left button when it is not needed.

8. With terminal block, no soldering iron can be used easily, and the wire bonding point is retained.

9. Input voltage 4.0~38V. (The input voltage must be 1.5v higher than the output voltage)

10. Adjustable output voltage range is continuously adjustable from 1.25V to 36V. (The input voltage must be 1.5V higher than the output voltage)

11. The output current can up to 5A, it is recommended to use within 4.5A.

12. The output power can up to 75W.

13. High conversion efficiency, up to 96% (efficiency related to input, output voltage, current, voltage difference)

14. Load regulation S (I) ≤ 0.8%, voltage regulation S (u) ≤ 0.8%

15. With overheat protection and short circuit protection.

Onboard voltmeter self-calibration method:

1. When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds to release, the voltmeter and the output voltage indicator "OUT" flash synchronously. At this time, the output voltage adjustment mode is entered; similarly, the voltmeter is displayed. When inputting the voltage, long press the right button for 2 seconds and then release, the voltmeter and the input voltage indicator "IN" flash synchronously, then enter the input voltage adjustment mode;

2. Tap the right button to increase the voltage by one unit. Tap the left button to lower the voltage by one unit. Since the voltage of one unit is less than 0.1V, you need to press 1-5 times to see the voltmeter. Changed by 0.1V, the specific continuous button press depends on the currently displayed voltage value, the higher the current display voltage, the fewer the number of presses;

3. After the voltage adjustment is completed, long press the right button for 2 seconds and then release, then the voltage calibration mode can be exited, and all parameter settings are automatically powered down.

Note:

The method only needs to be calibrated once to get accurate voltage value over the entire voltage range. It is designed to meet your high precision requirements, please be assured of using.
