1. Input Connection: Connect the AC-L and AC-N pins to the live and neutral wires of the AC power source, respectively. Ensure proper insulation and safety precautions when handling AC voltage.
2. Output Connection: Connect the DC+ and DC- pins to the load or device requiring 5V DC power. Verify the polarity to avoid damage to the connected device.
3. Mounting: Secure the module in a well-ventilated area to prevent overheating. Avoid placing it near heat-sensitive components.
4. Testing: Before connecting the module to your final circuit, test it with a multimeter to confirm the output voltage and ensure proper operation.

• Safety First: Always handle the module with care when working with AC voltage. Use proper insulation and avoid touching live connections.
• Load Requirements: Ensure the connected load does not exceed the module's maximum output current of 0.6A.
• Ventilation: Operate the module in a well-ventilated environment to maintain optimal performance and prevent overheating.
• Isolation: If used in sensitive applications, consider adding additional isolation between the AC input and the rest of the circuit.

The HLK LD2410B can be used to power an Arduino UNO by providing a stable 5V DC output. Below is an example of how to connect the module to an Arduino UNO:

1. Connect the AC-L and AC-N pins to the AC power source.
2. Connect the DC+ pin to the Arduino's 5V pin.
3. Connect the DC- pin to the Arduino's GND pin.

// Example Arduino code to blink an LED using power from the HLK LD2410B
// Ensure the HLK LD2410B is properly connected to the Arduino UNO

int ledPin = 13; // Pin connected to the onboard LED

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

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

Q: Can the HLK LD2410B be used with a 12V device?
A: No, the HLK LD2410B provides a fixed 5V DC output. It is not suitable for devices requiring 12V.

Q: Is the module safe to use in outdoor environments?
A: The HLK LD2410B is not weatherproof. If used outdoors, it must be enclosed in a weatherproof housing.

Q: Can I use this module to power multiple devices?
A: Yes, as long as the total current draw does not exceed 0.6A.

Q: Does the module require additional components for operation?
A: No, the HLK LD2410B is a self-contained power supply module. However, you may add fuses or filters for additional protection and noise reduction.
