Doc Ver: HW-06DL-091121
This UBEC is only designed for using lithium battery pack; NiMH / NiCd battery pack is not recommended. The input polarity must be correct;otherwise the UBEC will be damaged. Please check the polarity carefully before connecting the battery pack.

8 Amps Switching-Mode UBEC
1. Why do you need UBEC?
The 8A-UBEC is a switching-mode DC-DCregulator 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, andbecause a switchingmode 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.

How to Use the UBEC?
Change the output voltage The voltage is changed by an output-voltage selection switch. Working status indicator (LED) The LED shows the status of theoutput. It lights when the UBEC has the normal output. If it couldn’t light, please check the battery connections. Battery capacity indicators (4 LEDs)
