The
8A-UBEC is a switch-mode DC-DC regulator supplied with a
2-3 cells lithium battery pack and it outputs a consistent safe voltage
for your receiver, gyro and servos. It is very suitable for nitro powered
RC helicopter (bigger than 30 class) and big fixed-wing aircraft.
Compared with the linear mode UBEC, the overall efficiency of the
switch-mode BEC 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.
1 Specification
1.1 Output Voltage: 5V or 6V
(Changeable with an output-voltage select switch )
2.1 Designed with an advanced switch mode DC-DC regulator IC.
2.2 The output current is very large.
2.3 With the output short-circuit
protection function.
2.4 A metal shield covers almost all
the electronic components, and a filter ring is attached with the output
wires to significantly reduce the electromagnetic interference.
2.5 Automatically detects the number
of the lithium battery pack (2 cells or 3 cells).
2.6 Shows the battery capacity with 4
indicators (LEDs).
2.7 Shows the working status with an
indicator (LED), lights when the output is in normal range.
2.8 There are 2 output leads to
reduce the resistance when connecting the UEBC to the receiver.
