2.1 Adopting switching power supply structure design, the frequency of switching power supply main control chip is 300KHz, and it has over-current and over-temperature protection functions,its efficiency is as high as 92%;

2.2 small and light;

2.3 The electronic device is protected by the shielding cover, the output line is equipped with a magnetic ring, which greatly reduces electromagnetic interference and ensures the normal operation of the receiver

2.4 It has a protection function to prevent the polarity of the power supply from being reversed. If the power supply is accidentally reversed, it will not cause UBEC damage

Compared with the BEC with linear voltage regulator, the advantages of BEC with switching power supply mode are mainly reflected in: when using more than 3 strings (11.1V) batteries, it can greatly reduce the heating of BEC and improve the overall efficiency.

For example: when using 4 strings of lithium batteries, the voltage is about 14.8V in normal use.

●Using the transmission method of linear voltage stabilization, to output a current of 5V/1A, the power supply terminal must also input a current of 1A. So there will be 14.8V×1A= 14.8W power consumption on BEC, but the actual useful output of BEC is only 5V×1A=5W, so the overall efficiency is only 5/14.8= 33.8%, and the power consumption of 9.8W is converted into Heat, so it will cause the BEC to overheat, and the chip will enter the protection state and cannot work;

●Using the switching power supply mode, to output a current of 5V/1A, our actual test shows that the power supply terminal only needs to input a current of 0.38A, that is, 14.8V×0.38A= 5.6W.
