How to Use Phoenix QUINT4-PS/1AC/5DC/5/PT: Examples, Pinouts, and Specs

The Phoenix QUINT4-PS/1AC/5DC/5/PT (Manufacturer Part ID: 2904595) is a compact and highly efficient industrial power supply unit designed to convert AC input to a stable DC output. With its robust design, wide input voltage range, and advanced protection features, this power supply is ideal for demanding industrial environments. It ensures reliable operation of connected devices and systems, even under challenging conditions.

• Industrial automation systems
• PLCs (Programmable Logic Controllers) and control panels
• Sensors and actuators in factory environments
• Communication and networking equipment
• LED lighting systems
• Any application requiring a stable 5V DC power source

The Phoenix QUINT4-PS/1AC/5DC/5/PT features screw terminal connections for input and output. Below is the pin configuration:

1. Mounting: Secure the power supply unit onto a DIN rail or a flat surface using the provided mounting clips.
2. Input Connection:
   • Connect the AC input wires to the L (Live) and N (Neutral) terminals.
   • Ensure the PE (Protective Earth) terminal is properly grounded for safety.
3. Output Connection:
   • Connect the + terminal to the positive input of your load.
   • Connect the - terminal to the ground or negative input of your load.
4. Power On:
   • After verifying all connections, switch on the AC power supply.
   • Check the LED indicators: the "DC OK" LED should light up, indicating proper operation.

• Input Voltage: Ensure the input voltage is within the specified range (100–240 V AC). Operating outside this range may damage the unit.
• Load Capacity: Do not exceed the maximum output current of 5 A. Overloading may trigger the protection mechanism.
• Ventilation: Install the unit in a well-ventilated area to prevent overheating. Avoid enclosing it in tight spaces without airflow.
• Wiring: Use appropriately rated wires for both input and output connections to handle the current safely.
• Polarity: Double-check the polarity of the output connections to avoid damaging connected devices.

The Phoenix QUINT4-PS/1AC/5DC/5/PT can be used to power an Arduino UNO. Below is an example wiring and code snippet:

1. Connect the + terminal of the power supply to the Arduino's 5V pin.
2. Connect the - terminal of the power supply to the Arduino's GND pin.

// Example code to blink an LED connected to pin 13 on the Arduino UNO
// Ensure the Arduino is powered by the Phoenix QUINT4-PS/1AC/5DC/5/PT

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 this power supply be used with 12 V DC input?

   • No, the unit is designed for AC input only. Using DC input may damage the device.

2. What happens if the load exceeds 5 A?

   • The power supply will activate its overload protection, shutting down the output. Once the overload is removed, it will automatically restart.

3. Is the unit suitable for outdoor use?

   • No, the power supply is not weatherproof. It should be installed in a dry, indoor environment.

4. Can I use this power supply to charge batteries?

   • While technically possible, it is not recommended unless the battery charging circuit includes proper current and voltage regulation.

By following this documentation, users can safely and effectively integrate the Phoenix QUINT4-PS/1AC/5DC/5/PT into their industrial or hobbyist projects.
