Hobbywing 5A UBEC 3-10S
Hobbywing 10A UBEC 2-6S
The UBEC is an external switching mode DC-DC regulator; it draws the DC voltage from 3-10S Lipo battery, drops it to a voltage level that is suitable for receivers and other electronic devices, and keep providing the stable current output up to 5Amp. As the UBEC has such a powerful output capability, so it is particularly applicable for large helicopters and fixed-wing aircraft that use 7S or above Lipos.
Part Number 86010020
Quiescent Current: 20mA
Input Voltage: 8- 42V (3-10S LiPo)
Size: 48x27x9mm (LxWxH)
Why do you need a high voltage UBEC?
The 5A-HV-UBEC is a switch-mode DC-DC regulator when used with a 3S to 10S Lipo battery pack the unit outputs a consistent safe power for your receiver, gyro and servos. It is best suited to big
electric RC models such as fixed-wing aircraft and helicopters which use more than 4 cells lithium battery.
Using this UBEC, the receiver can obtain the power supply directly from the main battery pack, so the additional battery pack for receiver is unnecessary.
Compared with the linear mode UBEC, the overall efficiency of the switch-mode UBEC is much higher, so it can extend the working time of the receiver battery pack, and because a switch mode
A UBEC can significantly reduce the heat emission, it can also avoid the loss of control caused by over-heating which is frequently happens using the linear mode UBEC.
