5A-HV Switch Mode UBEC
1.
Why do you need a high voltage UBEC?
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 such as fixed-wing aircrafts and helicopters which use more than 4
cells lithium battery.
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.

3.
Features:
3.1. Designed with an advanced switch mode DC-DC regulator IC, the max efficiency of the
chip is up to 92%.
3.2. The output current is very large, the continuous output current is up to 5 Amps, and the
burst output current is up to 7.5 Amps.
3.3. With the output short-circuit protection function.
3.4. A metal shield covers almost all the electronic components, and a filter (ferrite ring) is
attached with the output wires to significantly reduce the electromagnetic interference.
3.5. With ultra-wide input voltage from 8V-42V.
3.6. 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.
3.7. Shows the working status with an indicator (LED), it lights when the output is in normal
range.
3.8. It has a switch to turn on or turn off the output.
3.9. Accessory: A step-down voltage regulator with 0.7V down. (from 6.0V to 5.3V)
