The 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.
1.1 Output Voltage: 5V or 6V
(Changeable with an output-voltage select jumper )
1.2 Continuous output
current: 5 Amps
1.3 Burst output
current: 7.5 Amps
1.5 Quiescent current:
2.1 Designed with an
advanced switch mode DC-DC regulator IC, the max efficiency of the
chip is up to 92%.
2.2 The output current is very
2.3 With the output short-circuit
2.4 A metal shield covers almost
all the electronic components, and a filter is attached with the
output wires to significantly reduce the electromagnetic
2.5 With ultra-wide input voltage
2.6 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.
2.7 Shows the working status with
an indicator (LED), lights when the output is in normal range.
2.8 It has a switch to turn on or
turn off the output.
2.9 With a step-down voltage
regulator of 0.7V down as an accessory (From 6.0V to 5.3V).
