1. 3V When the UBEC output is set to 6V please connect the regulator between the receiver and the above Servos If you are using a servo can work with 6V input the 0 7V regulator is unnecessary2. User Manual of 8A UBEC 1 8 Amps Switching Mode UBEC 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 control caused by the over heat problem which is frequently happened with the linear mode UBEC 2 2 1 2 2 2 3 2 4 2 5 3 3 1 3 2 3 3 3 4 3 5 3 6 3 7 3 8 4 5 5 1 Specification Output 5V 8A or 6V 8A Changeable with an output voltage select switch Input 6V 12 6V 2 3 cells lithium battery pack Size 42mm 39mm 9mm length width height Weight 38g Quiescent current 60mA Features Designed with an advanced switching mode DC DC regulator IC The output current is very large the continuous output current is up to 8A and the burst output current is 15A Output short circuits protection function 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 electromagneti
3. c interference Automatically detects the number of the lithium battery pack 2 cells or 3 cells and shows the battery capacity with 4 indicators LEDs Shows the working status with an indicator LED lights when the output is in normal range 2 output leads to reduce the resistance when connecting the UEBC to the receiver Accessory A step down voltage regulator with 0 7V down from 6 0V to 5 3V Wiring Input j Voltage Indicators 4LEDs Full Mid Low Stop UBEC SA MAX 15A INPUT 6WY 12 6V 2 3 Lipo SERENE RF ae lt enpug toe a Voltage changing Switch Output Indicator Special Notes Although we have tried our best to reduce the electromagnetic interference caused by switching model UBEC it still may cause some interference to the receiver So please install the filter far away from the UBEC s main board and DON T stack the filter on the main board Please put the whole UBEC as far as possible away from the receiver De 5 3 6 2 6 3 6 4 6 5 Doc Ver HW O6DL 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 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
