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.

 
 
 
 

*This UBEC is an advanced switching regulator, provides over-current and over-heat protection function, and the

witching frequency is 300KHz.The max efficiency of this chip is 92%

 

*The smallest size and the lightest weight.

 

*Compare linear BEC with switch-mode BEC: When using a lithium battery pack more than 3s, a switch-mode BEC

has much higher efficiency than linear BEC.

 

*For a traditional linear BEC: For example?a 4s lithium battery pack has a typical voltage of 14.8V, in order to let

BEC outputs 5V/1A, the current flow into BEC is at least 1A, so the power on BEC is 14.8V* 1A=14.8W. But the

useful output power is only 5V*1A=5W, so the efficiency of BEC is 5W/14.8W=33.8%, the redundant power

14.8W-5W=9.8W changes to heat, which makes the BEC very hot.

 

*For a switch-mode BEC: In the above case, in order to let BEC outputs 5V/1A, the current flow into BEC is only

0.38A (actual test data), so the power on BEC is 14.8V* 0.38V=5.6W, and the efficiency of BEC is 5W/5.6=89.3%
