UBEC-8A (Large Current BEC)


User Manual


A step-down voltage regulator wire (6V to 5.3V)  


The 8A-UBEC is a switch-mode DC-DC regulator supplied with a 2-3 cells lithium battery pack and it outputs a consistent safe voltage for your receiver, gyro and servos. It is very suitable for nitro powered RC helicopter (bigger than 30 class) and big fixed-wing aircraft.

Compared with the linear mode UBEC, the overall efficiency of the switch-mode BEC is much higher, so it can extend the working time of the receiver battery pack, and because a switch mode UBEC can significantly reduce the heat emission, it can avoid the loss of control caused by the over-heat problem which is frequently happened with the linear mode UBEC.
