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 ), and it outputs 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. Features - Brand: Hobbywing.- Color: as shown in the pictures.- Material: durable hard PCB board.- and 3A UBEC 5V 6V Max 5A Lowest RF Noise BEC Voltage Regulator- Designed with an advanced switch mode DC-DC regulator IC.- The output is powerful even working with 4 to 6 cells Lipo battery.- 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.
