User Guide
Introduction about the UBEC
- “- + S”：“-”represents the “GND wire”, “+” represents “Voltage Output”, and “S” represents “Signal Input & Output”.
- Signal input pins must correspond to signal output pins. That’s “CH1” corresponds to “CH1”,“CH2” corresponds to “CH2”,
- When only connecting to the “-/+” pins, all the 8 channels can function as the BEC output.
- The LED indicator indicates the work status of the UBEC:
The red LED turns on solid indicates the main input is normal, The blue LED turns on solid indicates the backup input is normal, and green LED turns on solid indicates the UBEC output is normal. - The external switch used for turning on/off the UBEC.
- The external switch is used for turning on/off the UBEC output, the main power and backup power supply will be disconnected once the external switch is of
Change the Output Voltage
You can change the BEC output voltage to 5.2 / 6.0V / 7.4V / 8.4V / 9V / 12V via the 5-in-1 DIP switch on the UBEC (as shown below):
5.2V Output: Please slide the switches (#1 #2 #3 #4 #5) to OFF
6.0V Output: Please slide the switches (#1 #2 #3 #4) to OFF, switch #5 to ON.
7.4V Output: Please slide the switches (#1 #2 #3) to OFF, switch #4 to ON, and switch #5 to ON or OFF(it doesn’t matter).
8.4V Output: Please slide the switches (#1 #2) to OFF, switch #3 to ON, and switch (#4 #5) to ON or OFF(it doesn’t matter).
9.0V Output: Please slide the switches #1 to OFF, switch #2 to ON, and switch (#3 #4 #5) to ON or OFF(it doesn’t matter).
12V Output: Please slide the switch #1 to ON, and switch (#2 #3 #4 #5) to ON or OFF(it doesn’t matter).
Remark:
1.From left to right (as shown in the picture), they are switch #1, switch #2, and switch # 3，switch # 4，switch # 5. 2.When the main power supply and the backup power supply are connected to the unit, please do not set the UBEC voltage much lower than the voltage of the backup power supply (i.e. setting the UBEC voltage to 5V, but connecting a 2S LiPo battery with the voltage of over 5V as the backup power supply).
Otherwise, the voltage of the backup power supply may damage the connected electronic device when the main power supply is broken.
Connection Diagram
When functioning purely as an UBEC for one-channel
output: The Red/Black JR connector can be
connected to relevant devices like receiver,
flight control for providing voltage output & current output.
When functioning purely as an UBEC for multi-channel
parallel output: The Red/Black JR connectors can
be connected to relevant devices like receiver,
flight control for providing (up to) 8-channel
parallel voltage output & current output.
When the unit is used for connecting the gyro and servos on a helicopter.
Other Information
- When your brushless ESC has no built-in BEC, then there is no need to make any change to the ESC, you only need to connect the input end of the UBEC to the battery pack in parallel and plug the output end (of the UBEC) into any unoccupied channel on the receiver.
- When your brushless ESC has a built-in BEC, then you need to disconnect the BEC output of the brushless ESC. That’s removing the Red wire from the cable which is used for connecting the brushless ESC to the receiver, and then connect the input end of the main power supply of the UBEC to the battery pack in parallel and plug the output end (of the main power supply of the UBEC) into any unoccupied channel on the receiver.
