Why use UBEC?
UBEC is an external switching power supply regulator that is separate from brushless ESC. It can obtain DC voltage suitable for operation of receivers and other devices from a high input voltage (5.5V - 23V) and is stable. With up to 3A of output current, it can easily power receivers, gyroscopes, and more than four servos, making it ideal for remote model helicopters and large fixed-wing aircraft that use high voltage and multiple servos.

Features

2.1 Adopting the design of switching power supply structure, the frequency of the main control chip of the switching power supply is 300KHz, and it has over-current and over-temperature protection functions, and the chip efficiency is as high as 92%;
2.2 The body is small and light;
2.3 The electronic device is protected by a shield, and the output cable is equipped with a magnetic ring, which greatly reduces electromagnetic interference and ensures the receiver works normally.
2.4 It has the protection function of preventing the polarity of the power supply from being reversed. If the power supply is accidentally connected, it will not cause UBEC damage.
Advantages compared to traditional BEC:
Compared with the BEC with linear regulator, the BEC with switching power supply is mainly reflected in the fact that when three strings (11.1V) or more are used, the BEC heating can be greatly reduced and the overall efficiency can be improved.
For example, when using 4 strings of lithium batteries, the voltage during normal use is about 14.8V.
● Adopting the linear voltage regulation mode, to output 5V/1A current, the power supply terminal must also input 1A current. Therefore, there will be 14.8V × 1A = 14.8W of power consumption on the BEC. However, 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 will not work;
● Use the switching power supply mode to output 5V/1A current. Our actual test shows that the power supply only needs to input 0.38A current, that is, 14.8V×0.38A= 5.6W.
