Instructions for Use:

1. Input Connection:

   • Connect the input terminals to the AC power supply (85-265 VAC).
   • Ensure proper isolation and safety measures to avoid electrical hazards.

2. Output Connection:

   • Connect the output terminals to the load requiring 5V DC at up to 0.5A.
   • Verify the polarity before connecting to avoid damage to the load.

3. Thermal Management:

   • Ensure adequate ventilation or cooling to prevent the device from exceeding 150掳C.
   • Avoid operating in environments with temperatures below -40掳C or above 85掳C for extended periods.

4. Power-On Sequence:

   • The device will start up within 150ms when the input voltage is applied.
   • Monitor the output voltage to ensure it stabilizes at 5V.

5. Protection Features:

   • The device includes thermal shutdown protection, which activates if the temperature exceeds 150掳C.
   • Once the temperature returns to a safe level, the device will automatically restart.

6. Efficiency:

   • The typical efficiency of 85% is achieved under full load conditions at 230VAC input.
   • Efficiency may vary at different input voltages and load conditions.

7. Storage:

   • Store the device in a dry, cool place with temperatures between -40掳C and 150掳C.
   • Avoid exposure to excessive humidity and corrosive environments.

8. Handling:

   • Handle the device with care to avoid mechanical damage.
   • Follow ESD (Electrostatic Discharge) precautions to prevent damage to the internal components.
