HiModel U-BEC, 8-15A Switch-Mode, 2-3S, 5V/6V selectable. brc217
HiModel U-BEC, 8-15A Switch-Mode, 2-3S, 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 Nixx. 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 percent!
Designed with an advanced switch-mode DC-DC regulator IC, the max efficiency of the chip is up to 95 percent. The output current is very large, the continuous output current is up to 8A, and the burst output current is 15A. With the output short-circuit protection function and the over-heat protection. The UBEC features a large heatsink with metal shield which covers almost all the electronic components, and a specially made filter is attached with the output wires to significantly reduce any electromagnetic interference.
The UBEC automatically detects the number of cells within the lithium battery pack (2 cells or 3 cells), and shows the battery capacity with 4 indicators (LED).
Specifications:
* Output: 5V/8A or 6V/8A (Changeable)
* Input: 6V-12.6V (2-3S lithium battery pack)
* Size: L42 x W39 x H9mm/1.65 x 1.54 x 0.35 in
* Weight: 34g (1.2oz)
* Quiescent current: 60mA
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.
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 10-15 Standard Size Servos!
A brilliant device which enables the use of several servos without the need of a receiver battery - saving weight and money!
