8-15A Switch-Mode UBEC w/Ferite Ring Input: 6V-12.6V 8A con /15A brust

Product Information

The 8A large current UBEC is specially designed for fuel-powered RC models. With a 2-3S Lipo battery pack, it has the powerful output to drive all the equipments on your model.

1. Specification:


1.1. Output: 5V/6V selectable, 8A con /15A brust

1.2. Input: 6V-12.6V (2-3s lithium battery pack)

1.3. Size: 42mm*39mm*9mm (length*width*high)

1.4. Weight: 34g

2. Features:

2.1. The 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%

2.2. The smallest size and the lightest weight.

2.3. Don¡¦t worry about the polarity of battery pack, if the polarity is not correct, the UBEC can¡¦t work, but it will not be destroyed. What you need to do is just swap the battery pack polarity.

2.4. A shield covers almost all the electronic components on PCB, and a ferrite ring is attached with the output wires to decrease the electromagnetic interference,



2.5. Compare linear BEC with switch-mode BEC: the switch-mode BEC has much higher efficiency than linear BEC.

2.5.1. For a traditional linear BEC: For example¡Aa 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.

2.5.2. 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/5.6W=89.3%.

3. Other functions:

Battery polarity protection: Over-heat protection; Output wires short-circuit protection; Working status indicator(LED); Battery volume indicators;
