We are a manufacturer of electronic components, electronic modules for a large number of products.We are the factory!With more than 10 years of PCB development experience, the product quality is good, the price is excellent.A large number of wholesale sales of global buyers, welcome to purchase.
Module performance and characteristics:
●With power indicator
●With voltmeter display and the voltmeter can be self-calibrated. A more advanced voltage microprocessor is adopted, the error of the voltmeter 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)
●Touch the button to switch between measuring input or output voltage, and there is an indicator light to show which voltage is being measured, and the setting is saved, even if the power is turned off and on again.
●The voltmeter can be turned off, and it can be easily realized by touching the button on the left when it is not needed.
●With terminal blocks, it is convenient to use without soldering iron, and the connection points of welding wires are reserved.
●Input voltage 4.0~38V. (The input voltage must be more than 1.5v higher than the output voltage)
●Adjustable output voltage range 1.25V～36V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
●The output current can reach 5A, and it is recommended to use it within 4.5A.
●The output power can reach 75W.
●High conversion efficiency, up to 96% (efficiency is related to input, output voltage, current, and pressure difference)
●Load regulation rate S(I)≤0.8%, voltage regulation rate S(u)≤0.8%
●With overheating protection and short circuit protection function
Self-calibration method of on-board voltmeter:
1. When the on-board voltmeter displays the output voltage, press and hold the button on the right for 2 seconds and then release it. The voltmeter and the output voltage indicator "OUT" flash simultaneously, and then enter the output voltage adjustment mode; similarly, display on the voltmeter When inputting voltage, press and hold the button on the right side for 2 seconds and then release, the voltmeter and input voltage indicator "IN" will flash simultaneously, and then enter the input voltage adjustment mode;
2. Tap the right button to increase the voltage by one unit, and tap the left button to decrease the voltage by one unit; since the voltage value of a unit is less than 0.1V, you need to press 1-5 times to see the voltmeter Changed by 0.1V, the specific number of consecutive keystrokes depends on the currently displayed voltage value. The higher the currently displayed voltage, the fewer the number of times to press;
3. After the voltage adjustment is completed, press and hold the right button for 2 seconds and then release it. At this time, you can exit the voltage calibration mode, and all parameter settings will be automatically saved after power-off.
