How to Use DC 24V 25A 600W: Examples, Pinouts, and Specs

The NUOFUWEI S-24-600 is a high-performance direct current (DC) power supply unit designed to deliver a stable 24V output with a maximum current of 25A, providing up to 600W of power. This power supply is ideal for powering high-current devices, industrial equipment, LED lighting systems, and other electronic circuits requiring a reliable DC power source.

• Industrial automation systems
• High-power LED lighting arrays
• CNC machines and 3D printers
• Motor drivers and robotics
• Laboratory testing and prototyping
• Battery charging systems

The following table outlines the key technical details of the NUOFUWEI S-24-600 power supply:

The NUOFUWEI S-24-600 features screw terminal connections for input and output. The pin configuration is as follows:

• Voltage Adjustment Knob: A small potentiometer near the output terminals allows fine-tuning of the output voltage (±10%).

1. Input Connection:

   • Ensure the input voltage selector switch is set to the correct position (110V or 220V) based on your AC mains supply.
   • Connect the live (L), neutral (N), and ground (GND) wires to the input terminals securely.

2. Output Connection:

   • Connect the V+ and V- terminals to your load or circuit. Use appropriate gauge wires to handle the high current (25A max).

3. Voltage Adjustment:

   • If necessary, use a small screwdriver to adjust the voltage potentiometer to fine-tune the output voltage.

4. Power On:

   • After verifying all connections, power on the unit by supplying AC input. The built-in fan will activate to maintain optimal operating temperature.

• Load Requirements: Ensure the connected load does not exceed the maximum power rating of 600W or the current limit of 25A.
• Ventilation: Install the power supply in a well-ventilated area to prevent overheating. Do not block the fan or ventilation holes.
• Safety: Always disconnect the power supply from the AC mains before making any wiring changes.
• Wire Gauge: Use wires rated for at least 25A for the output connections to avoid overheating or voltage drops.
• Fusing: Consider adding an external fuse or circuit breaker on the input side for additional protection.

The NUOFUWEI S-24-600 can be used to power an Arduino UNO and other peripherals. Below is an example of how to connect the power supply to an Arduino UNO:

1. Set the output voltage to 24V using the adjustment knob.
2. Use a DC-DC step-down converter to reduce the 24V output to 5V for the Arduino UNO.
3. Connect the step-down converter's input to the V+ and V- terminals of the power supply.
4. Connect the step-down converter's 5V output to the Arduino UNO's 5V pin and GND.

// Example code to blink an LED connected to pin 13 of the Arduino UNO
// Ensure the Arduino is powered via the step-down converter (5V input).

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:

   • Verify that the input voltage selector switch is set correctly (110V or 220V).
   • Check the AC input connections (L, N, and GND) for proper wiring.
   • Ensure the load is connected securely to the output terminals.

2. Overheating:

   • Ensure the power supply is installed in a well-ventilated area.
   • Check for obstructions blocking the cooling fan or ventilation holes.
   • Reduce the load if it exceeds the maximum power rating.

3. Voltage Fluctuations:

   • Use the voltage adjustment knob to stabilize the output voltage.
   • Verify that the input AC voltage is stable and within the specified range.

4. Fan Not Working:

   • The fan operates based on temperature. If the unit is not hot, the fan may not activate.
   • If the fan fails to operate under load, contact the manufacturer for support.

Q1: Can I use this power supply to charge batteries?
A1: Yes, but ensure the battery charging voltage and current are within the power supply's specifications. Use a charge controller for optimal performance and safety.

Q2: Is the output voltage adjustable?
A2: Yes, the output voltage can be adjusted within ±10% of 24V using the built-in potentiometer.

Q3: Can I connect multiple devices to the output?
A3: Yes, as long as the total current draw does not exceed 25A and the total power does not exceed 600W.

Q4: Does the power supply have built-in protection?
A4: Yes, it includes overvoltage, overcurrent, and short-circuit protection.
