Manuale di istruzioni del regolatore CC-CC a commutazione Hobbywing UBEC-3A

1. Introduzione

The Hobbywing UBEC-3A is a high-efficiency switch-mode DC-DC regulator designed to provide a stable power supply to your receiver, gyroscopes, and servos. It is compatible with 2-6 cell Lithium Polymer (LiPo) battery packs or 5-18 cell Nickel-Metal Hydride (NiMh) / Nickel-Cadmium (NiCd) batteries. This UBEC is particularly suitable for use in RC helicopters and other remote-controlled models requiring a reliable power source independent of the main motor battery.

2 Caratteristiche

• Designed with an advanced switch-mode DC-DC regulator integrated circuit for high efficiency.
• Provides powerful output even when operating with 4 to 6 cell LiPo batteries.
• Includes battery polarity reversal protection to prevent damage from incorrect connections.
• Features a metal shield covering electronic components and a specially designed filter on the output wires to significantly reduce electromagnetic interference (EMI).
• An indicator LED displays the working status, illuminating when the output voltage rientra nel normale intervallo operativo.

3. Configurazione e installazione

Proper installation is crucial for the safe and reliable operation of your UBEC-3A. Please follow these steps carefully:

1. Connessione di ingresso: Connect the input wires of the UBEC (typically red and black, thicker gauge) directly to your main flight battery. Ensure correct polarity: red to positive (+), black to negative (-). The UBEC supports 2-6S LiPo or 5-18 cell NiMh/NiCd batteries.
2. Volume di uscitatage Selezione: Locate the output-voltage select switch on the UBEC unit. This switch allows you to choose between 5V and 6V output. Set the switch to your desired voltage before connecting to your receiver and servos.
3. Connessione di uscita: Connect the output wires of the UBEC (typically a standard servo connector) to an available channel on your receiver. Ensure the polarity matches the receiver's input (signal, positive, negative).
4. EMI Filter Installation: The UBEC-3A includes a ferrite ring on the output wires. For optimal electromagnetic interference reduction, ensure the output wires are passed through this ferrite ring as shown in the product image. This helps to filter out noise that could affect sensitive electronic components.
5. Montaggio: Securely mount the UBEC unit in a location that is protected from physical damage, moisture, and excessive vibration. Ensure adequate airflow if possible, although the UBEC-3A generates minimal heat.

4. Istruzioni per l'uso

Once the UBEC-3A is correctly installed and connected, operation is straightforward:

• Accensione: Connect your main flight battery to the UBEC input. The UBEC will automatically power on.
• Indicatore di stato: Observe the LED indicator on the UBEC unit. If the LED is illuminated, it indicates that the UBEC is functioning correctly and providing stable output voltage.
• Spegni: Disconnect the main flight battery from the UBEC input to power off the unit.

Always ensure that the total current draw of your receiver, servos, and other connected devices does not exceed the continuous output current rating of the UBEC (3 AmpS).

5. Manutenzione

The Hobbywing UBEC-3A is designed for durability and requires minimal maintenance. However, following these guidelines can help ensure its longevity:

• Mantenere pulito e asciutto: Protect the UBEC from dust, dirt, and moisture. Avoid operating it in wet conditions.
• Ispezionare le connessioni: Periodically check all input and output wire connections for signs of wear, corrosion, or loose contacts. Ensure all plugs are securely seated.
• Ispezione fisica: Inspect the UBEC unit for any physical damage, such as cracks in the casing or damaged wires.
• Magazzinaggio: When not in use, store the UBEC in a cool, dry place away from direct sunlight and extreme temperatures.

6. Risoluzione Dei Problemi

If you encounter issues with your UBEC-3A, consider the following troubleshooting steps:

• No Power Output / LED Off:
  • Check the input battery connection. Ensure it is securely connected and fully charged.
  • Verify input battery voltage rientra nell'intervallo specificato (5.5 V-26 V).
  • Check for correct input polarity. The UBEC has polarity reversal protection, but incorrect connection should still be avoided.
  • Inspect output connections to the receiver for proper seating and polarity.
• Intermittent Power / Glitches:
  • Ensure the ferrite ring on the output wires is correctly installed to minimize electromagnetic interference.
  • Controllare che non vi siano collegamenti allentati sia sul lato di ingresso che su quello di uscita.
  • Verify that the total current draw of your connected devices does not exceed the UBEC's continuous current rating. Overloading can cause voltage drops or intermittent operation.
• Volume di uscita erratotage:
  • Confirm the position of the output-voltage select switch.
  • Use a multimeter to measure the actual output voltage to confirm it matches the selected setting.

If problems persist after performing these checks, contact Hobbywing customer support or your retailer for further assistance.
