The HDR-15-5 is straightforward to use in a variety of applications. Follow the steps below to integrate it into your circuit:

1. Secure the HDR-15-5 onto a DIN rail (TS-35/7.5 or TS-35/15) in your control panel or enclosure.
2. Ensure the power supply is mounted in a well-ventilated area to prevent overheating.

1. Connect the AC line (L) and neutral (N) wires to the input terminals of the HDR-15-5.
2. Ensure the input voltage is within the specified range (85-264 VAC).

1. Connect the +V terminal to the positive rail of your circuit.
2. Connect the -V terminal to the ground rail of your circuit.
3. Verify that the connected load does not exceed the maximum output current of 2.4A.

1. After all connections are secure, power on the AC input.
2. Use a multimeter to verify the output voltage is 5V DC before connecting sensitive devices.

• Load Regulation: Ensure the connected load is within the power supply's rated capacity to avoid triggering overload protection.
• Ventilation: Maintain adequate airflow around the power supply to prevent overheating.
• Safety: Always disconnect the AC input before making any wiring changes.
• Polarity: Double-check the polarity of the output connections to avoid damaging connected devices.

The HDR-15-5 can be used to power an Arduino UNO and other peripherals. Below is an example wiring setup:

1. Connect the +V terminal of the HDR-15-5 to the Arduino's 5V pin.
2. Connect the -V terminal of the HDR-15-5 to the Arduino's GND pin.
3. Ensure the total current draw of the Arduino and peripherals does not exceed 2.4A.

Here is a simple Arduino sketch to blink an LED when powered by the HDR-15-5:

// Blink an LED connected to pin 13
// Ensure the HDR-15-5 is providing a stable 5V to the Arduino UNO

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: Input AC voltage is not connected or is out of range.
   • Solution: Verify the AC input connections and ensure the voltage is within 85-264 VAC.

2. Overload Protection Triggered

   • Cause: The connected load exceeds the maximum output current of 2.4A.
   • Solution: Reduce the load to within the rated capacity.

3. Overheating

   • Cause: Insufficient ventilation or operation in a high-temperature environment.
   • Solution: Improve airflow around the power supply and ensure ambient temperature is within -30°C to +70°C.

4. Output Voltage Fluctuations

   • Cause: Unstable input voltage or excessive load changes.
   • Solution: Stabilize the input voltage and avoid rapid load changes.

Q1: Can the HDR-15-5 be used with DC input?
A1: Yes, the HDR-15-5 supports DC input in the range of 120-370 VDC.

Q2: Is the HDR-15-5 suitable for outdoor use?
A2: No, the HDR-15-5 is not weatherproof and should only be used in indoor environments.

Q3: What happens if the load exceeds 2.4A?
A3: The power supply's overload protection will activate, shutting down the output to protect the device.

Q4: Can I use the HDR-15-5 to charge batteries?
A4: The HDR-15-5 is not designed for direct battery charging. Use a dedicated battery charger for this purpose.

By following this documentation, you can safely and effectively use the HDR-15-5 in your projects.
