HiModel U-BEC, 5A Switch-Mode, 3-10S, 5V/6V selectable. brc868
HiModel U-BEC, 5-7A Switch-Mode, 3-10S, 5V/6V selectable.
Just about all ESCs with a built in BEC (Battery Elimination Circuit) will only support 2-3 servos at flight battery voltages of anything higher than 3S (11.1v) Lithium or 12 Cells Ni-xx. This Switch-Mode UBEC is designed to replace the need (and weight) of a receiver battery providing power to run the receiver and several servos. With ultra-wide input voltage from 8V-42V.
Any 'OPTO' or 'OPTO-ISOLATED ESC' will need a receiver battery to power the servos. This UBEC provides power to the receiver (without the need of a receiver battery) as well as supplying power to run several servos. This UBEC is an advanced switching regulator, features over-current and over-heat protection with a switching frequency of 300KHz. The max efficiency of this chip is 92%!
Specifications:
* Output: 5v & 6v (selectable)
* Current: 5A - 7.5A
* Ripple: <50mVp-p
* Switch to turn output on or off
* input voltage: 8V-42V (3-10S lithium battery pack, 5-30 cells Ni-xx)
* Supplied with full instructions
The comparison of a linear BEC and switch-mode BEC: When using a lithium battery pack more than 3S (11.1V), a switch-mode BEC has much higher efficiency than linear BEC (often found in ESCs).
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.
A shield covers almost all the electronic components on PCB, and a ferrite ring is attached with the output wires to decrease any external electromagnetic interference.
This UBEC can also be used on ESCs which have a BEC fitted - you must disable the BEC first, do this by simply removing the 'RED' wire from your ESC 3-lead plug. Then wire in the UBEC to safely power up to 8-10 Standard Size Servos!
A brilliant device which enables the use of several servos without the need of a receiver battery - saving weight and money!
We use these in our display models on 6V with Spektrum radios and can confirm they perform very well in all applications!
