Product Description :
Specification: Output: 5V 3A Power Input: 5.
5-23V (2S-5S Li-ion Battery Pack or 5-15 cells nickel-metal hydride/nickel-cadmium battery pack) Weight: Approx.
11g Ripple: Less than 50mVp-p (2A/12V) Package includes: 1 x UBEC 3A 5V Receiver Power Supply Advantages compared with traditional BEC: When using more than 3s (11.
1v) batteries, BEC heating can be greatly reduced and overall efficiency can be improved.
For example, when using 4s lithium batteries, the voltage is about 14.
8v in normal use.
Adopting linear voltage regulation mode, the power supply must input 1A current to output 5V/1A current.
Therefore, there will be 14.
8V x 1A = 14.
8W power consumed on BEC.
However, the actual useful output of BEC is only 5V x 1A=5W, so the overall efficiency is only 5/14.
8= 33.
8%.
Besides, the power consumption of 9.
8W will be converted into heat, which will cause BEC overheating and the chip entering the protection state and fail to work.
Adopting switching power supply mode, the actual tests show that there is only need to input 0.
38A current to output 5V/1A current.
The power is 14.
8V x 0.
38A = 5.
6W, so the overall efficiency is 5/5.
6=89.
3%.
