Hobbywing UBEC-8A (Large Current BEC)

  • Description
  • Shipping&Payment
  • Return Policies

The 8A-UBEC is a switching-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 switching-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.

2  Features  Features

2.1 Designed with an advanced switching-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.
