This is 5V/6V 3A Switch-Mode Ultimate BEC – Voltage Regulator.
The module is designed with an advanced switch mode DC-DC regulator IC which eliminates the fear of overheating. It offers a powerful output with 5V and 3A.
A metal shield covers almost all the electronic components, and a specially made filter is attached with the output wires to significantly reduce electromagnetic interference. Also, it has output short circuit protection which makes it ideal for RC applications.
