Instructions for Use:

1. Input Connection:

   • Connect the AC input to the designated pins on the TOP247Y.
   • Ensure the input voltage is within the specified range (180VAC to 375VAC).

2. Output Connection:

   • Connect the load to the output terminals.
   • The output voltage is fixed at 5VDC and can supply up to 7A.

3. Thermal Management:

   • Ensure adequate ventilation or cooling to keep the operating temperature within the specified range (-40°C to 85°C).
   • Avoid placing the device in environments with high humidity or where condensation may occur.

4. Electrical Safety:

   • Before connecting or disconnecting any wires, ensure the power is turned off.
   • Ensure the insulation resistance and dielectric strength meet the specified values to prevent electrical hazards.

5. Storage:

   • Store the device in a dry environment with temperatures between -40°C and 125°C.
   • Avoid exposure to corrosive substances.

6. Testing:

   • Test the device under no-load conditions first to verify proper operation.
   • Measure the no-load input power to ensure it is within the specified limit (0.15W).

7. Maintenance:

   • Regularly inspect the device for signs of wear or damage.
   • Replace any damaged components immediately to avoid performance issues or safety hazards.
