8A Switching-Mode UBEC
1.
Why do you need UBEC?
The 8A-UBEC is a switching-mode DC-DC regulator supplied with a 2-3 cells lithium battery
pack and outputs a consistent safe voltage for your receiver, gyro and servos. It is very suitable
for nitro powered RC helicopter (above 30 class) and big fixed-wing aircraft.
Compared with the linear mode UBEC, the overall efficiency of the switching-mode BEC is
much higher, so it can extend the working time of the receiver battery pack, and because a
switching- mode UBEC can significantly reduce the heat emission, it can avoid the loss of con
-
trol caused by the over-heat problem which is frequently happened with the linear mode UBEC.

3.4.
A metal shield covers almost all the electronic components, and a specially made
filter (ferrite ring) is attached with the output wires to significantly reduce the electro
magnetic interference.

Shows the working status with an indicator (LED), lights when the output is in normal
range.
3.7.
2 output leads to reduce the resistance when connecting the UEBC to the receiver.
