How to Use HDR 5V/15W/2.4A: Examples, Pinouts, and Specs

The HDR-15-24 by Mean Well is a high-density power supply module designed to deliver a stable 5V DC output with a maximum power rating of 15W and a current capacity of 2.4A. This compact and efficient module is ideal for powering a wide range of electronic devices, including microcontrollers, sensors, and small appliances. Its robust design ensures reliable performance in both industrial and consumer applications.

• Powering microcontroller boards (e.g., Arduino, Raspberry Pi)
• Supplying power to sensors and actuators in IoT systems
• Driving small DC motors or LED strips
• Industrial control systems and automation
• General-purpose DC power supply for electronic projects

The HDR-15-24 module features screw terminal connections for input and output. Below is the pin configuration:

1. Mounting: Secure the HDR-15-24 module onto a DIN rail in your enclosure or panel.
2. Input Connection:
   • Connect the AC live wire to the L terminal.
   • Connect the AC neutral wire to the N terminal.
   • Optionally, connect the Earth Ground wire to the Ground (GND) terminal for safety.
3. Output Connection:
   • Connect the +V terminal to the positive input of your load.
   • Connect the -V terminal to the negative input of your load.
4. Power On: Once all connections are secure, supply AC power to the module. The module will convert the AC input to a stable 5V DC output.

• Ensure the input voltage is within the specified range (85-264 VAC).
• Do not exceed the maximum output current of 2.4A to avoid triggering the overload protection.
• Use appropriately rated wires for both input and output connections.
• For safety, always disconnect the power supply before making any wiring changes.
• If using the HDR-15-24 with sensitive electronics, consider adding a capacitor across the output terminals to reduce noise.

The HDR-15-24 can be used to power an Arduino UNO directly via its 5V pin. Below is an example circuit and Arduino code:

1. Connect the +V terminal of the HDR-15-24 to the 5V pin of the Arduino UNO.
2. Connect the -V terminal of the HDR-15-24 to the GND pin of the Arduino UNO.

// Example code to blink an LED connected to pin 13 of the Arduino UNO
// Ensure the HDR-15-24 is providing a stable 5V to the Arduino

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. Can the HDR-15-24 power multiple devices simultaneously?

   • Yes, as long as the total current draw does not exceed 2.4A.

2. Is the HDR-15-24 suitable for outdoor use?

   • No, the module is not weatherproof. Use it in a dry, indoor environment.

3. What happens if the load exceeds 2.4A?

   • The overload protection will activate, shutting down the output to protect the module.

4. Can I use the HDR-15-24 with a DC input?

   • Yes, the module supports a DC input range of 120-370 VDC.

By following this documentation, users can effectively integrate the HDR-15-24 into their projects and ensure reliable operation.
