Features:

2-1.The UBEC is an advanced switching regulator with over-current and over-heat
protection function, and the maximum efficiency of the system is nearly 90%.
2-2.The small size and the light weight make it very convenient to use.
2-3.The comparison of linear BEC and switch-mode BEC: When using a lithium battery
pack more than 3S, a switch-mode BEC has much higher efficiency than linear BEC.
* For a traditional linear BEC, For example, a 4S lithium battery pack has a typical voltage of
14.8V, in order to let BEC output 5V/1A, the current flow into the BEC is at least 1A, so the
power on BEC is 14.8V* 1A=14.8W. But the useful output power is only 5V*1A=5W, so the
efficiency of the linear mode BEC is just 5W/14.8W=33.8%, the redundant power
14.8W-5W=9.8W changes to heat, which makes the BEC very hot.
* For a switch-mode BEC in the above case, in order to let BEC output 5V/1A,
the current flow into BEC is only 0.38A (actual test data), so the power on
BEC is 14.8V* 0.38A =5.6W, and the efficiency of BEC is 5W/5.6W=89.3%.
2-4. Don’t worry about the polarity of battery pack. If the polarity is not correct, the UBEC
can’t work, but it will not be destroyed. What you need to do is just swap the battery
pack polarity.
2-5. A shield covers almost all the electronic components on PCB, and a ferrite ring is
attached with the output wires to decrease the electromagnetic interference.

How to use UBEC?

3-1. Important hint: Switch mode UBEC may cause some electromagnetic interference to receiver,
Please install the UBEC with a distance at least 5cm away from the receiver.
3-2. When ESC HAS NOT built-in BEC function
No change is needed for the ESC, just connect the input cables of UBEC with the battery, and
plug the output cable (connector) of the UBEC into one spare channel of the receiver.
