Special Explanation
5.1.
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.
5.2.
This UBEC is only designed for using lithium batter pack; we don’t recommend the
use of NiMh / NiCd battery pack.
5.3.
The input polarity must be correct; otherwise the UBEC will be damaged. Please
check the polarity carefully before connecting the battery pack.
6.
How to Use the UBEC?
6.1.
Change the output voltage
The voltage is chosen by an output-voltage select switch.
6.2.
Working status indicator (LED)
The LED shows whether the output is normal or not. It lights when the UBEC has
the normal output. If it doesn’t light, please check the battery connections.
6.3.
Battery capacity indicators (4 LEDs)
○ means the LED lights, ● means the LED does not light
When you are using a 3 cells lithium battery pack, if there is only one LED („STOP“)
lights, that means the voltage is less than 9.9v, please change the battery pack as
soon as possible, otherwise it will be damaged because of over-discharging. For
such a fully-discharged 3S battery pack, if the voltage is less than 9V, please don’t
use it again before it is recharged, otherwise the UBEC may mistakenly consider
this battery as 2 cells, so the power capacity indication function will be confused.
6.4.
Turn on or turn off the output
Set the main switch to the „ON“ position to turn on the output; Set the main switch to
the “OFF“ position to turn off the output.
6.5.
About the 0.7V step-down voltage regulator
Allowing use of Futaba servo models 9241, 9251, 9253, 9254, 9255, 9256 and other
digital servos not capable of handling 6V. This small device can change the voltage
from 6V to 5.3V. When the UBEC output is set to 6V, the step-down voltage regula
tor is useful.
Method: Just connect the regulator inline between the Gyro and the rudder servo
(Or between the receiver and the servo), that’s OK.
If you are using a servo that can accept 6V input, the regulator is not required.
