How to Use Convertisseur AC/DC LM100-23B12R2: Examples, Pinouts, and Specs

The LM100-23B12R2 is an AC/DC power converter manufactured by Mornsun. This component is designed to transform alternating current (AC) to direct current (DC) with a specific output voltage and current rating. It is suitable for a wide range of electronic applications, including industrial automation, instrumentation, and consumer electronics.

• Industrial Automation: Powering control systems and sensors.
• Instrumentation: Providing stable DC power for measurement devices.
• Consumer Electronics: Supplying power to various household electronic devices.
• Embedded Systems: Powering microcontrollers and other digital circuits.

1. Connection to AC Source:

   • Connect the AC(L) pin to the live wire of the AC source.
   • Connect the AC(N) pin to the neutral wire of the AC source.

2. DC Output Connection:

   • Connect the +Vout pin to the positive terminal of the load.
   • Connect the -Vout pin to the negative terminal (ground) of the load.

3. Frame Ground:

   • Connect the FG pin to the chassis or earth ground for safety.

• Heat Dissipation: Ensure adequate ventilation or heat sinking to maintain the operating temperature within the specified range.
• Overload Protection: Use appropriate fuses or circuit breakers to protect against overcurrent conditions.
• Isolation: Maintain proper isolation between the AC input and DC output to prevent electrical hazards.
• Mounting: Securely mount the converter to avoid mechanical stress and vibrations.

1. No Output Voltage:

   • Possible Cause: No AC input or incorrect wiring.
   • Solution: Verify the AC input connections and ensure the AC source is active.

2. Overheating:

   • Possible Cause: Inadequate ventilation or excessive load.
   • Solution: Improve ventilation, reduce the load, or add a heat sink.

3. Output Voltage Fluctuations:

   • Possible Cause: Unstable AC input or load variations.
   • Solution: Ensure a stable AC input and check for consistent load conditions.

• Check Connections: Ensure all connections are secure and correct.
• Measure Input and Output: Use a multimeter to measure the AC input and DC output voltages.
• Inspect for Damage: Look for any visible signs of damage or overheating on the converter.
• Consult Datasheet: Refer to the manufacturer's datasheet for detailed specifications and guidelines.

If you are using the LM100-23B12R2 to power an Arduino UNO, here is a simple example code to blink an LED:

// Pin 13 has an LED connected on most Arduino boards.
const int ledPin = 13;

// The setup function runs once when you press reset or power the board.
void setup() {
  // Initialize the digital pin as an output.
  pinMode(ledPin, OUTPUT);
}

// The loop function runs over and over again forever.
void loop() {
  digitalWrite(ledPin, HIGH);   // Turn the LED on (HIGH is the voltage level).
  delay(1000);                  // Wait for a second.
  digitalWrite(ledPin, LOW);    // Turn the LED off by making the voltage LOW.
  delay(1000);                  // Wait for a second.
}

This code will blink the LED connected to pin 13 of the Arduino UNO, powered by the LM100-23B12R2 AC/DC converter.
