Description

This high-performance BEC module is engineered to provide clean, regulated power to sensitive digital FPV and telemetry systems like the SIYI HM30 Air Unit. Its wide input voltage compatibility makes it suitable for multirotor platforms ranging from standard 4S freestyle builds to high-voltage 12S+ heavy-lift and industrial drones.

The module features robust construction and high-efficiency switching circuitry to minimize thermal load and ensure stable 12V rail performance under varying flight loads. This stability is critical for preventing video dropouts and system resets during aggressive maneuvers or high-current draw scenarios.

Key Features

  • Ultra-Wide Input Voltage Support for maximum build flexibility.
  • High-Current 10A Continuous Output for powering multiple subsystems.
  • High-Efficiency Switching Regulator (≥90%) reduces heat generation and extends flight time.
  • Robust XT60 Input Connector ensures secure, high-current power connections.
  • Compact and Lightweight Design optimizes space and weight within the airframe.
  • Durable PCB Construction with conformal coating for resistance to vibration and minor moisture.

Applications

  • Powering the SIYI HM30 digital HD FPV/telemetry air unit on heavy-lift mapping and inspection drones.
  • Providing clean 12V power to digital video systems on high-voltage (6S-12S+) long-range FPV platforms.
  • Integrating into industrial UAV builds requiring stable power for auxiliary payloads alongside the HM30 unit.

Frequently Asked Questions

What is the maximum input voltage this BEC module can handle?

The SIYI BEC Module is rated for a maximum input voltage equivalent to an 18S LiPo battery pack, which is approximately 67.2 volts. It is designed to step down this high voltage to a stable 12V output for powering the HM30 Air Unit and other compatible accessories.

Can this module power devices other than the SIYI HM30 Air Unit?

Yes, provided the device operates at 12V and does not exceed the module's 10A continuous current limit (50W max power). It is suitable for powering other FPV video transmitters, cameras, or telemetry systems that require a clean 12V supply. Always verify your device's voltage and current requirements before connection.

How should I connect this BEC module to my drone's power system?

Connect the module's XT60 input connector directly to your main flight battery leads or power distribution board (PDB). The output should be wired to your HM30 Air Unit's power input. Ensure all connections are secure and properly insulated. The module should be mounted in a location with adequate airflow to aid in heat dissipation during high-load operation.
