This component is widely used in powering electronic devices, industrial control systems, LED lighting, and other low-voltage applications. Its compact design and robust performance make it suitable for both professional and hobbyist projects.

• Powering microcontrollers, sensors, and other electronic modules
• Industrial automation and control systems
• LED lighting systems
• Security and surveillance equipment
• DIY electronics projects

Below are the key technical details of the Selec RPS60-12-CE:

The Selec RPS60-12-CE features screw terminals for easy wiring. Below is the pin configuration:

1. Wiring the Input:

   • Connect the L terminal to the live wire of the AC mains.
   • Connect the N terminal to the neutral wire of the AC mains.
   • Ensure proper insulation and secure connections to avoid electrical hazards.

2. Wiring the Output:

   • Connect the +V terminal to the positive input of your load (e.g., a microcontroller or LED strip).
   • Connect the -V terminal to the ground of your load.

3. Powering On:

   • After verifying all connections, plug the power supply into the mains and switch it on.
   • Measure the output voltage using a multimeter to ensure it is 12V DC before connecting sensitive devices.

• Safety First: Always disconnect the power supply from the mains before making any wiring changes.
• Load Requirements: Ensure the total current draw of connected devices does not exceed 5A.
• Ventilation: Install the power supply in a well-ventilated area to prevent overheating.
• Polarity: Double-check the polarity of the output connections to avoid damaging your devices.
• Fusing: Consider adding a fuse on the input side for additional protection.

The Selec RPS60-12-CE can be used to power an Arduino UNO. Below is an example setup:

1. Connect the +V terminal to the Arduino's VIN pin.
2. Connect the -V terminal to the Arduino's GND pin.

Here is a simple Arduino sketch to blink an LED when powered by the Selec RPS60-12-CE:

// Blink an LED connected to pin 13
// Ensure the Arduino is powered via the VIN and GND pins

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: Incorrect wiring or no AC input.
   • Solution: Verify the AC input connections and ensure the mains power is on.

2. Overheating:

   • Cause: Insufficient ventilation or excessive load.
   • Solution: Ensure proper airflow around the power supply and reduce the load to within the 5A limit.

3. Voltage Fluctuations:

   • Cause: Unstable AC input or faulty power supply.
   • Solution: Check the AC input for stability. If the issue persists, replace the power supply.

4. Device Not Powering On:

   • Cause: Incorrect polarity or loose connections.
   • Solution: Double-check the output connections and ensure correct polarity.

Q: Can I use this power supply for a 24V device?
A: No, the Selec RPS60-12-CE provides a fixed 12V output and is not suitable for 24V devices.

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

Q: Can I connect multiple devices to the output?
A: Yes, as long as the total current draw does not exceed 5A.

Q: Does it have short-circuit protection?
A: Yes, the Selec RPS60-12-CE includes built-in short-circuit and overload protection.

By following this documentation, you can safely and effectively use the Selec RPS60-12-CE in your projects.
