Описание товара


Note: This module has a maximum power of 20 W. When you test the output voltage if the output voltage is not higher than the input voltage, adjust the potentiometer clockwise, the output voltage will rise. Remember not to counterclockwise to adjust the use of antihypertensive modules trying to do, must ensure that the output voltage is set higher than the input voltage, so as not to damage the module!
IN + input positive IN - input negative OUT + output positive OUT - output negative
index:
This module has a maximum power of 20W
Input voltage range: 3.5V-35V (must ensure that the set output voltage is higher than the input voltage)
Output voltage range: 5.0V-56V
Enter the maximum current: 3A (according to the power conservation to calculate the rated current output current
Uin * Iin * Efficiency = Uout * Iout)
Input continuous operating current: 2A (ventilation and heat dissipation conditions good output voltage and input voltage ratio can not be greater than 3)
Appearance size: length * width * height 4.3cm * 3.0cm * 1.2cm
Work efficiency tests are as follows:
5V to 12V:
5V output 12V = (11.93 * 0.500) / (5.02 * 1.383) * 100% = 86.3% (due to the test did not consider the actual line output voltage efficiency is better than the test efficiency)
12V to 24V:
12V to 24V = (23.84 * 0.799) / (12.03 * 1.747) * 100% = 90.7% (due to the test did not consider the actual drop in line output efficiency is better than the test efficiency)
Typical application:
1,3.7 to 5V to do mobile charge treasure
2, boost drive LED string (need to increase the appropriate current limiting resistor)
3,7.4V boost 12V applications in the aircraft model camera
Note: High current work will be a lot of heat Please pay attention to strengthen the ventilation and heat.
