Instructions for TOP246Y

1. Input Connection:

   • Connect the AC input to the designated terminals on the TOP246Y module. Ensure the input voltage is within the specified range (85VAC to 265VAC).

2. Output Connection:

   • Connect the DC output terminals to your load. The fixed output voltage is 5VDC with a maximum current of 3.5A.

3. Mounting and Heat Dissipation:

   • For optimal performance and longevity, mount the module on a heatsink if operating near maximum load conditions or in high ambient temperatures.

4. Power-On Sequence:

   • Apply the AC input voltage to start the converter. The module will automatically adjust to the correct output voltage and begin supplying power to the load.

5. No-Load Operation:

   • Under no-load conditions, the input power consumption is minimized to approximately 0.1W.

6. Operating Environment:

   • Ensure the operating environment adheres to the specified temperature and humidity ranges to prevent damage and ensure reliable operation.

7. Safety Precautions:

   • Handle with care and observe all electrical safety precautions. Avoid exposing the module to excessive heat, moisture, or mechanical stress.
