4. عملیاتي لارښوونې

Once properly installed and wired, the FCHUB-12S V2 provides stable power distribution and regulated outputs for your drone components.

4.1 د بریښنا ویش

The PDB efficiently distributes power from your LiPo battery to up to four ESCs, handling high continuous and burst currents. The integrated current sensor provides accurate current consumption data to your flight controller.

4.2 Regulated Outputs (BECs)

• 5V Output (5V pad): Provides a stable 5.1V DC output with up to 5A continuous current (6A max). This is suitable for powering your flight controller, receiver, GPS, and other 5V components. It features short-circuit tolerance and overcurrent protection.
• 12V Output (12V pad): Provides a stable 12.0V DC output with up to 4A continuous current (5A max), provided the input voltage is 12V or higher. If input voltage د 12V څخه ښکته دی، د تولید حجمtage will match the input. Ideal for powering VTX, cameras, and other 12V accessories.
