Usage:

1. Connection:
   • Connect the primary winding terminals to the 230V AC mains supply.
   • Connect the secondary winding terminals to the load or circuit requiring 9V AC.
   • The center tap (0V) can be used for creating a dual power supply (±9V) or for grounding purposes.
2. Mounting:
   • Securely mount the transformer using the appropriate hardware and ensure it is protected from mechanical stress and vibration.
3. Safety:
   • Ensure all connections are properly insulated and secure to prevent electrical hazards.
   • Do not exceed the rated current of 300mA to avoid overheating and potential damage.

Caution:

• Handle the transformer carefully to avoid physical damage.
• Ensure the primary voltage matches the rated 230V AC to prevent damage.
• Avoid short-circuiting the secondary windings to prevent overheating and damage.
• Ensure proper ventilation to avoid overheating during operation.
