5. Setup and Installation

The HGLRC BEC 5-12V Power Module offers flexible connection options. Always ensure power is disconnected from your system before making any connections.

5.1. Input Power Connection

1. Identify Input Terminals: Locate the input terminals on the BEC module, typically labeled "BAT" or "IN". These are designed for your main power source (e.g., LiPo battery).
2. Connect Input Cable: Solder or connect the provided input cable to your power source. Ensure correct polarity: positive (+) to positive, negative (-) to negative. The module supports 8.4V to 28V input.

5.2. Output Power Connection

1. Identify Output Terminals: Locate the output terminals, typically labeled "OUT+" and "OUT-".
2. Connect Output Cable: Connect the provided output cable to the device you wish to power. Ensure correct polarity.
3. Select Output Voltage: The module supports both 5V and 12V output. The specific method for switching between these voltages is usually indicated on the module itself or through a jumper/solder pad. Refer to the markings on your specific module for voltage selection.

5.3. Remote Control Connection (Optional)

If your module supports remote control functionality, connect the designated "RX" or control signal pin to an available channel on your RC receiver or flight controller. This allows you to remotely switch the BEC module on or off.

6. Operating Instructions

Once the module is correctly installed and connected, follow these steps for operation:

1. Power On: Connect your main power source (e.g., LiPo battery) to the input terminals of the BEC module.
2. Verify Output: Use a multimeter to verify that the output voltage matches your desired setting (5V or 12V) before connecting sensitive components.
3. Remote Control (if applicable): If you have connected the module to an RC channel, use your remote controller to activate or deactivate the BEC output as needed. Consult your flight controller or RC receiver manual for channel assignment and configuration.
4. Monitor Performance: During operation, ensure the module does not overheat. While designed for stable performance, excessive load or poor ventilation can affect its efficiency.

7. Maintenance

The HGLRC BEC 5-12V Power Module is designed for durability, but proper maintenance can extend its lifespan and ensure reliable operation:

• Regular Inspection: Periodically inspect the module and its connections for any signs of wear, corrosion, or loose wiring.
• Cleaning: Keep the module free from dust, dirt, and debris. Use a soft, dry brush or compressed air for cleaning. Avoid using liquid cleaners.
• Environmental Protection: Operate and store the module in a dry environment, away from direct sunlight and extreme temperatures.
• Secure Mounting: Ensure the module is securely mounted to prevent vibrations or physical stress on its components and connections.
