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 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 much higher. 1 Specification 1.1 Output Voltage: [email protected]
