HOBBYWING UBEC 3A, MAX 5A 2-6S LIPO 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. Features 1.Uses an advanced switch mode DC-DC regulator IC. 2.The output is powerful enough even working with 4S to 6S Lipo battery. 3.Battery polarity reversal protection. 4.A metal shield and a filter significantly reduce the electromagnetic interference. 5.The working status is shown by an LED, it lights when the UBEC works normally. Specification Weight: 11g Size: 43mm*17mm*7mm Input: 5.5V-26V (2-6S Lipo or 5-18 cells NiMH /NiCd) Continuous output current: 3 Amps Output Voltage: 5V@3A or 6V@3A (Selectable by using a jumper connector)
