HOBBYWING UBEC 5V-3A 2-6s

Good profit 5V 6V 3A UBEC fully shielded BEC switching power supply 2s 3S 4S 6s lithium battery

Why use UBEC?

UBEC is an external switching power supply voltage regulator separated frombrushless ESC . It can obtain the DC voltage suitable for the receiver and other equipment from the high input voltage (5.5V-23V) , and it is stable continuously providing an output current up to 3A, as can easily receiver, a gyroscope , a four or more servo power supply, and therefore very suitable for remote control modelhelicopter , and the use of large high-voltage and a plurality of servo fixed-wingaircraft.

* 5V / 6V output can be switched! 
* Reverse power protection polarity protection! 
* LED working status indicator! 
* Full screen + output line magnetic ring effectively eliminate electromagnetic interference!

2.6 advantages compared with the traditional BEC: The 
use of switching power supply BEC and BEC compared with the linear regulator, the advantages are mainly reflected in: When using 3 strings (11.1V) above the battery, you can greatly reduce the BEC Fever, and improve the overall efficiency. 
For example: When using 4 series lithium battery, the voltage is about 14.8V under normal use. 
● Adopts the linear voltage regulation method, to output 5V / 1A current, the power terminal must also input 1A current. So there will be 14.8V × 1A = 14.8W power consumption on the BEC, however, BEC practical useful output is only 5V × 1A = 5W, so the overall efficiency of only 5 / 14.8 = 33.8%, while 9.8W of power is converted into Heat, so it will cause the BEC to overheat and the chip will not work. 
● Using the switching power supply, to output 5V / 1A current, our actual test shows that the power supply end can only input the current of 0.38A, that is, 14.8 V × 0.38A = 5.6W, the overall efficiency is 5 / 5.6 = 89.3%
