Description

The Premium Line BECs are lightweight and provide the most versatile solution for most power applications.

Reverse polarity protection, as well as TDK input and output capacitors to prevent burnout due to voltage spikes.

The BEC measures the output current and increases the output voltage by a few millivolts depending on the output load. This compensates the voltage drop in the connection from the BEC to the flight controller and to the receiver, and keeps the voltage more stable.

Bright blue power indicator LED.

Inclusive LDO power supply (5.00V /- 0.03V) for the Sensor Boards, Sensor Hub X2, or Sensor Hub X8.

Please connect the minus/black wire of the BEC as close as possible to the main battery, as this is used as the ground reference for the voltage measurements.

The BEC comes without flight controller cable, so please select the correct cable to match your flight controller:

To Sensor Board, Sensor Hub X2, or Sensor Hub X8

1. 050: backup power cable for Pixhawk 2.1 / Molex CLIK-Mate 2.0 6p / L = 150mm

To backup connector of Pixhawk 2.1 or any other equipment

2. 041/042/043: Flight Controller Cable

To flight controller -> This cable need to be purchased separately.

3. 5.0V output cable with wire leads / L = 150mm

5.0V output for telemetry or any other equipment.

4. 12.0V output cable with wire leads / L = 150mm

12.0V output for gimbal or any other equipment.


Why is the output voltage to the flight controller 5.35V and not 5.0V?

Flight controllers such as the Pixhawk have internally a 3-way power selector over an ideal diode chip. The 3 ways are: USB, the power port, and the servo rail. The flight controller can be powered by either one of those power sources. The flight controller is designed to select as the internal power supply whichever power source has a voltage higher by 0.25V to any other power source, as long as this voltage does not exceed 5.70V. To prevent the internal ideal diode from switching too often between different power sources, a slightly higher input voltage (5.35V) is supplied by the BEC.


Mounting

Use double side tape or screw onto the frame by removing the M3 screws and drilling holes into the frame. Reinstall the screws through the frame. The original screws will be too short, so please replace them with longer ones according to the thickness of your frame.
