The following table outlines the key technical details of the POWER SUPPLY 5V 5AMP:

The POWER SUPPLY 5V 5AMP typically has the following connections:

1. Connect the AC Input:

   • Connect the AC-L terminal to the live wire of your AC power source.
   • Connect the AC-N terminal to the neutral wire of your AC power source.
   • Ensure proper insulation and safety precautions when handling AC connections.

2. Connect the DC Output:

   • Connect the +5V terminal to the positive input of your load or circuit.
   • Connect the GND terminal to the ground of your load or circuit.

3. Verify Connections:

   • Double-check all connections to ensure they are secure and correct.
   • Use a multimeter to confirm the output voltage is 5V before connecting sensitive devices.

4. Power On:

   • Plug the power supply into an AC outlet and switch it on.
   • Monitor the output to ensure stable operation.

• Load Requirements: Ensure the total current draw of your connected devices does not exceed 5A.
• Ventilation: Place the power supply in a well-ventilated area to prevent overheating.
• Polarity: Always observe correct polarity when connecting the DC output to your circuit.
• Safety: Avoid touching the AC terminals while the power supply is connected to mains power.

The POWER SUPPLY 5V 5AMP can be used to power an Arduino UNO via its 5V pin. Below is an example of how to connect it:

1. Connect the +5V terminal of the power supply to the 5V pin on the Arduino UNO.
2. Connect the GND terminal of the power supply to the GND pin on the Arduino UNO.

// Example code to blink an LED connected to pin 13 of the Arduino UNO
// Ensure the Arduino is powered by the POWER SUPPLY 5V 5AMP

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. No Output Voltage:

   • Cause: AC input is not connected or is faulty.
   • Solution: Verify the AC input connections and ensure the power source is active.

2. Output Voltage is Not 5V:

   • Cause: Overload or short circuit on the output.
   • Solution: Disconnect the load and check for short circuits. Ensure the total load does not exceed 5A.

3. Power Supply Overheats:

   • Cause: Insufficient ventilation or excessive load.
   • Solution: Ensure proper airflow around the power supply and reduce the load if necessary.

4. Intermittent Operation:

   • Cause: Loose connections or unstable AC input.
   • Solution: Check all connections and ensure the AC input voltage is stable.

Q: Can I use this power supply to charge USB devices?
A: Yes, but you will need a USB breakout board or adapter to connect the 5V output to a USB port.

Q: Is this power supply suitable for outdoor use?
A: No, this power supply is not weatherproof and should only be used in dry, indoor environments.

Q: What happens if I exceed the 5A current limit?
A: The power supply's overload protection will activate, shutting down the output to prevent damage.

Q: Can I use this power supply with a Raspberry Pi?
A: Yes, the 5V 5A output is sufficient to power a Raspberry Pi and its peripherals. Ensure proper connections to the Pi's power input.
