UBEC

Whats a UBEC's.

UBEC stands for Ultimate Battery Eliminator Circuit. This device converts a higher input voltage to a lower consistent voltage. Making it safer to run receivers and servos at a lower voltages. 
Compared to older BEC's that were linear and not that efficient. A UBEC uses switch-mode technology which is more efficient.

We Have three to choose from it just depending on your input voltages and the required output. This comes down to what is needed for your application.

The Hi-Model 8 Amps. 5V / 6V Switch-Mode UBEC is very popular when you wish to replace a NiMh RX pack and exchange to a higher voltage Lipo pack. It has a set of LED light which illuminate as a visual representation of the packs voltage. This allows the user to stop operation when voltages are low. Especially important for lithium packs.

There is a switch that allows the output voltage to be selected from either 5V or 6V. Next to the switch is your output leads. This is your converted voltage supply. It has an filter which is an ferrite ring that helps eliminate any EMI (Electromagnetic interference). But the PCB is also surround in shield which helps eliminate any interference as well. This shielding helps reduce noise when a RC receiver is used.
