Connection Structure
To connect the 5V 2A SMPS Power Supply, follow these steps:
1. Connect the AC power source:
Connect the AC power cable to Pin 1 (VCC) and Pin 2 (GND). Ensure the voltage range of the AC power source is within the specified range of 100-240V AC.
2. Connect the load:
Connect the positive terminal of the load to Pin 3 (VOUT+).
Connect the negative terminal of the load to Pin 4 (VOUT-).
3. Ensure proper grounding:
Connect Pin 2 (GND) to the system ground to provide a reference point for the power supply.
4. Leave Pins 5 and 6 unconnected:
Do not connect Pins 5 and 6 to any component or system, as they are not internally connected and should not be used.
Important Notes
Ensure the input voltage is within the specified range to avoid damaging the power supply.
The output voltage is regulated to 5V DC, and the maximum current rating is 2A. Do not exceed the recommended current rating to avoid overheating or damaging the power supply.
Use proper insulation and safety precautions when working with electrical components to avoid electrical shock or injury.
