Features:

Designed with an advanced switch mode DC-DC regulator IC.
The output is powerful even working with 2 to 6 cells Lipo battery.
Battery polarity reversal protection.
A metal shield covers almost all the electronic components, and a specially made filter is attached with the output wires to significantly reduce the electromagnetic interference.
The working status is shown by an indicator (LED), lights when the output is in normal range.

Description:

The 3A-UBEC is a switch-mode DC-DC regulator supplied with a 2-6 cells
Lithium battery pack (or 5-18 cells NiMh /NiCd battery).
It ouput a consistent safe voltage for your receiver, gyro and servos.
It is very suitable for RC helicopter.
Compared with the linear mode UBEC, the overall efficiency of the switch-mode UBEC is higher.
