Matek UBEC DUO with Aux Control

Matek UBEC DUO Dual 4A/5~12V & 4A/5V Outputs with Built-in Battery Monitor and Aux Control​

Image icon Manual544.57 KB

We sell a lot of different voltage regulators on Flying Tech, but the Matek UBEC DUO is the one that stands out from them all, simply because it does most things and of course being made by Matek you know it will be reliable.

It provides voltage regulation, noise filtering, voltage monitoring and a RC power on / off function.

The UBEC itself is a 2-6S high-efficiency switching voltage regulator with dual output connectivity, which allows you to power flight tech and additional accessories independently. One output channel is capable of supplying a constant 4Amps at 5V for your RX or Flight Controller. The other channel offers 4Amps with a selectable voltage: output 5V, 6V, 7.2V &12V. This channel also features an inbuilt power switch that is operated by a spare Aux Channel on your radio control. It can be used to power and switch on/off a wide variety of equipment, such as Multi-rotor Gimbals, Video Transmitters, FPV camera systems, HV Servos, navigation/landing lights, bomb drops, etc.

I am using this item to provide power from a 2 cell 6.6v Li-Po reicever pack to a high torgue sali winch servo in a R/C yatcht. Should the out-1 voltage be set at 6v or 7.2v? Fully charged the Li-Po battery has 7.96v.

By admin on

It would depend on the voltage requirements of your servo. If the servo accepts 6V, then 6V would be appropriate.
