Szín: 1db - 5V / 12V 2S~6S RC UBEC 5V 3A legalacsonyabb RF zaj BEC teljes árnyékolás zavarásgátló kapcsoló szabályozó

The full name of UBEC is Ultra Battery Elimination Circuit, which separates
the built-in BEC from the Electronic Speed Controller (ESC) and becomes an
independent external voltage stabilizer to provide greater output power for the
load, so it is also called external BEC. UBEC works in the mode of switching
power supply (Switch Mode), compared with the linear mode (Linear Mode), it has
higher efficiency, and its own heat generation is small, so as to prolong the
service time of the battery pack.
The main reason for UBEC use is that the voltage of the input power supply
exceeds the allowable range of the electronic speed controller (ESC) on-board
BEC; or the current demanded by the load exceeds the allowable output range of
the electronic speed controller (ESC) on-board BEC.
The UBEC can obtain a DC voltage suitable for the operation of the receiver
and other equipment from the 2S-6S lithium battery pack, and can stably provide
an output current of up to 3A to power the receiver, FPV and multiple servos and
other equipment, so it is very Suitable for fixed wing and FPV use. With this
device, the power required by the receiver can be obtained directly from the
power supply, eliminating the need for a separate receiver battery pack.
How to use: 5V/12V switching voltage output: select by jumper cap. The jumper
is inserted into the two pins of pin1 and pin2 to select 5V output, and inserted
into the two pins of pin2 and pin3 to select 12V (YL6S3A01) output, please refer
to the picture; if the jumper cap is missing, the UBEC default output is 12V
(YL6S3A01).
Special instructions:
1. Although various measures have been taken to reduce electromagnetic
interference, the UBEC in switching voltage regulation mode cannot completely
avoid a small amount of electromagnetic interference during operation; in order
to ensure the normal operation of the receiver, please use the output filter
magnetic ring and The distance of the UBEC main control board should be as far
away as possible (the magnetic ring should not be superimposed on the main
control board), and the entire UBEC should be kept as far away as possible from
the receiver.
2. The positive and negative of the input power cannot be reversed, otherwise
the UBEC will be burned and cannot be repaired.
