How to Use 24V DC to 12V DC Converter: Examples, Pinouts, and Specs

The 24V DC to 12V DC Converter (Manufacturer: Swengao, Part ID: WG-24S1205) is a compact and efficient device designed to step down a 24V direct current (DC) voltage to a stable 12V DC output. This converter is widely used in power supply applications to ensure compatibility with 12V devices, such as automotive electronics, LED lighting systems, and industrial equipment.

• Automotive Systems: Powering 12V devices in vehicles with 24V electrical systems.
• LED Lighting: Supplying stable 12V power to LED strips and modules.
• Industrial Equipment: Providing 12V power to sensors, controllers, and other devices.
• Battery-Powered Systems: Converting 24V battery output to 12V for auxiliary devices.

The following table outlines the key technical details of the WG-24S1205 converter:

The WG-24S1205 converter has four input/output terminals. The pin configuration is as follows:

1. Connect the Input Terminals:
   • Connect the VIN+ terminal to the positive terminal of the 24V DC power source.
   • Connect the VIN- terminal to the ground (GND) of the 24V DC power source.
2. Connect the Output Terminals:
   • Connect the VOUT+ terminal to the positive input of the 12V device.
   • Connect the VOUT- terminal to the ground (GND) of the 12V device.
3. Verify Connections:
   • Double-check all connections to ensure proper polarity and secure wiring.
4. Power On:
   • Turn on the 24V DC power source. The converter will step down the voltage to 12V DC and supply it to the connected device.

• Input Voltage Range: Ensure the input voltage is within the specified range (18V to 36V DC). Exceeding this range may damage the converter.
• Load Capacity: Do not exceed the maximum output current of 5A or the maximum output power of 60W.
• Heat Dissipation: Install the converter in a well-ventilated area to prevent overheating. Use a heat sink or cooling fan if necessary.
• Polarity: Always observe correct polarity when connecting the input and output terminals. Reversed polarity can damage the converter.
• Protection Features: The converter includes built-in protection against overload, overvoltage, and short circuits. However, avoid intentionally testing these limits.

The WG-24S1205 can be used to power an Arduino UNO from a 24V DC power source. Below is an example circuit and Arduino code:

1. Connect the VIN+ and VIN- terminals of the converter to the 24V DC power source.
2. Connect the VOUT+ terminal to the Arduino UNO's VIN pin.
3. Connect the VOUT- terminal to the Arduino UNO's GND pin.

// Example code to blink an LED connected to pin 13 of the Arduino UNO
// Ensure the Arduino is powered via the WG-24S1205 converter

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output pin
}

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 I use this converter with a 12V input?
   • No, the input voltage must be between 18V and 36V DC for proper operation.
2. What happens if I reverse the input polarity?
   • The converter may be damaged. Always ensure correct polarity when connecting the input terminals.
3. Can I connect multiple devices to the output?
   • Yes, as long as the total current draw does not exceed 5A.

By following this documentation, you can safely and effectively use the Swengao WG-24S1205 24V DC to 12V DC Converter in your projects.
