Hobbywing BEC 3A UBEC ESC for 2-6s

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. Why do you need UBEC? The UBEC is a switch-mode DC regulator separated from ESC (ESC---Electronic Speed Controller for brushless/brushed motor), it will take high-voltage (5.5V to 26V) power from your battery pack and convert it to a consistent safe voltage for your receiver, gyro and servos. For traditional speed controller with a built-in BEC, it will very likely have only a limited ability to supply power to your receiver and servos without overheating. If you are using a high-voltage battery pack or have heavy servo load, you should consult the ESC specifications to determine what the stated recommendations or limitations are. In general, if you are using a 4 cells lithium battery pack, or more than a 12 cells Nickel based battery pack, you should consider using an UBEC because in such a case the built-in BEC of the ESC can support only 2 servos, which means it is not suitable for RC helicopter and big aircraft. Features Uses an advanced switch mode DC-DC regulator IC. The output is powerful enough even working with 4S to 6S Lipo battery. Battery polarity reversal protection. A metal shield and a filter significantly reduce the electromagnetic interference. The working status is shown by an LED, it lights when the UBEC works normally Specification Output Voltage: 5V/3A or 6V/3A (Selectable by using a jumper connector) Continuous output current: 3 Amps Input: 5.5V-26V (2-6S Lipo or 5-18 cells NiMH /NiCd) Size: 43mm*17mm*7mm (L*W*H) Weight: 11g Typical Applications: RC Helicopter with more than 4 servos. RC models with big-torque servos need large current supply
