The 3A-UBEC is a switch mode DC/DC regulator, it outputs a consistent safe voltage for the receiver, gyro and servos. It is very suitable for RC helicopter and other RC models especially when the built-in BEC in the speed controller has a very limited output capability. 1 Specification 1.1 Output Voltage: 5V@3A or 6V@3A (Selectable by using a jumper connector) 1.2 Continuous output current: 3 Amps 1.3 Input: 5.5V-26V (2-6S Lipo or 5-18 cells NiMH /NiCd) 1.4 Size: 43mm*17mm*7mm (L*W*H) 1.5 Weight: 11g 2 Features 2.1 Uses an advanced switch mode DC-DC regulator IC. 2.2 The output is powerful enough even working with 4S to 6S Lipo battery. 2.3 Battery polarity reversal protection. 2.4 A metal shield and a filter significantly reduce the electromagnetic interference. 2.5 The working status is shown by an LED, it lights when the UBEC works normally.
