Brand New free shipping Hobbywing 5A High Voltage (HV) Switch UBEC,Input 8-42V

Hobbywing High Voltage 5A Switch UBEC, Input Voltage 8-42V

The 5A-HV-UBEC is a switch-mode DC-DC regulator supplied with a 3-10 cells lithium battery pack and outputs a consistent safe power for your receiver, gyro and servos. It is very suitable for big electric RC models. 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 UBEC can significantly reduce the heat emission, it can avoid the loss of control caused by the over-heat problem which is frequently happened with the linear mode UBEC.
