How to Use 180W 36V 5A SMPS (WX-DC2416): Examples, Pinouts, and Specs

The 180W 36V 5A SMPS (WX-DC2416) is a high-efficiency Switching Mode Power Supply (SMPS) designed to convert AC mains power into a stable DC output of 36V at 5A. With a total power output of 180W, this SMPS is ideal for powering medium to high-power electronic devices and systems. Its compact design, high efficiency, and reliable performance make it suitable for a wide range of applications.

• Industrial automation systems
• LED lighting systems
• CNC machines and 3D printers
• Battery charging circuits
• Audio amplifiers
• Laboratory equipment

The following table outlines the key technical details of the WX-DC2416 SMPS:

The WX-DC2416 SMPS has input and output terminals for AC and DC connections. The pin configuration is as follows:

1. Input Connection:

   • Connect the AC mains power to the input terminals labeled L (Live), N (Neutral), and GND (Earth).
   • Ensure proper insulation and secure connections to avoid electrical hazards.

2. Output Connection:

   • Connect the load to the output terminals labeled V+ (Positive) and V- (Negative).
   • Verify that the load does not exceed the maximum output current of 5A.

3. Power On:

   • After verifying all connections, switch on the AC mains power. The SMPS will provide a stable 36V DC output.

4. Adjustments (if applicable):

   • Some versions of the WX-DC2416 may include a potentiometer for fine-tuning the output voltage. Adjust carefully if needed.

• Load Compatibility: Ensure the connected load operates within the SMPS's output voltage and current ratings.
• Ventilation: Install the SMPS in a well-ventilated area to prevent overheating.
• Safety: Avoid touching the SMPS while it is powered on, as high voltages are present on the input side.
• Fusing: Use an appropriate fuse on the input side to protect against overcurrent conditions.
• Polarity: Double-check the polarity of the output connections to avoid damaging the connected load.

The WX-DC2416 can be used to power an Arduino UNO and other peripherals. Below is an example circuit and code to control an LED using the SMPS as the power source.

1. Connect the SMPS output terminals (V+ and V-) to a DC barrel jack or directly to the Arduino's Vin and GND pins.
2. Connect an LED and a 220-ohm resistor to one of the Arduino's digital pins (e.g., pin 13).

// This code blinks an LED connected to pin 13 of the Arduino UNO.
// Ensure the SMPS provides a stable 36V DC to the Arduino's Vin pin
// through a voltage regulator or step-down module if required.

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
}

Note: The Arduino UNO operates at 5V. If using the WX-DC2416 directly, a step-down converter (e.g., LM2596) is required to reduce the 36V output to 5V.

1. Can I use this SMPS to charge a 36V battery?

   • Yes, but ensure the battery charging current does not exceed 5A. Use a charge controller for optimal performance.

2. Is the SMPS suitable for outdoor use?

   • No, the WX-DC2416 is not weatherproof. Use it in a dry, indoor environment.

3. Can I adjust the output voltage?

   • Some versions of the WX-DC2416 include a potentiometer for minor voltage adjustments. Check your specific unit.

4. What happens if the load exceeds 5A?

   • The SMPS includes overload protection and will shut down to prevent damage. Reduce the load and restart the SMPS.
