The Hobbywing 5A-HV-UBEC is a
switch-mode DC-DC regulator supplied with a 3-10 cells lithium battery pack and
outputs a consistent safe power for your receiver, gyro and servos. It is very
suitable for big electric RC models. Using this UBEC, the receiver can obtain
the power supply directly from the main battery pack, so the additional battery
pack for receiver is unnecessary.
Compared with the linear mode UBEC, the overall efficiency of the switch-mode
UBEC is much higher, so it can extend the working time of the receiver battery
pack, and because a switch 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.

BEC User Manual:
Features
-
Hobbywing 5A-HV High Voltage
UBEC 3-10S LiPo Input w/step-down voltage regulator
-
Designed with an advanced
switch mode DC-DC regulator IC, the max efficiency of the chip is up to 92%
-
The output current is very
large
-
With the output short-circuit
protection function
-
A metal shield covers almost
all the electronic components, and a filter is attached with the output
wires to significantly reduce the electromagnetic interference
-
With ultra-wide input voltage
from 8V-42V
-
Safe power on with the
polarity protection function. If the input polarity is not correct, the UBEC
can't work, but it will not be damaged. What you need to do is just swapping
the battery pack's polarity
-
Shows the working status with
an indicator (LED), lights when the output is in normal range
-
It has a switch to turn on or
turn off the output
