12V to 5V Power Supply with LED Indicator and Push Switch

This circuit is a 12V to 5V regulated power supply with an LED indicator. It uses a 5408 diode for reverse polarity protection, an LM340T5 7805 voltage regulator to step down the voltage to 5V, and a push switch to control the LED indicator. The circuit also includes capacitors for filtering and a resistor to limit the current through the LED.

Dual 5V Power Supply Distribution Circuit with Toggle Switch Control

This circuit consists of two 5V 5A power supplies connected to an AC wall plug point, providing DC output through a 12-way connector. The ground connections from both power supplies are interconnected and also connected to the ground pins of two toggle switches. The DC outputs from the power supplies are separately connected to different pins on the 12-way connector, with each power supply output being switchable via one of the toggle switches.

Usage Instructions

How to Use the HDR-15-24 in a Circuit

1. Mounting: Secure the HDR-15-24 module onto a DIN rail in your enclosure or panel.
2. Input Connection:
   • Connect the AC live wire to the L terminal.
   • Connect the AC neutral wire to the N terminal.
   • Optionally, connect the Earth Ground wire to the Ground (GND) terminal for safety.
3. Output Connection:
   • Connect the +V terminal to the positive input of your load.
   • Connect the -V terminal to the negative input of your load.
4. Power On: Once all connections are secure, supply AC power to the module. The module will convert the AC input to a stable 5V DC output.

Important Considerations and Best Practices

• Ensure the input voltage is within the specified range (85-264 VAC).
• Do not exceed the maximum output current of 2.4A to avoid triggering the overload protection.
• Use appropriately rated wires for both input and output connections.
• For safety, always disconnect the power supply before making any wiring changes.
• If using the HDR-15-24 with sensitive electronics, consider adding a capacitor across the output terminals to reduce noise.

Example: Using HDR-15-24 with an Arduino UNO

The HDR-15-24 can be used to power an Arduino UNO directly via its 5V pin. Below is an example circuit and Arduino code:

Circuit Diagram

1. Connect the +V terminal of the HDR-15-24 to the 5V pin of the Arduino UNO.
2. Connect the -V terminal of the HDR-15-24 to the GND pin of the Arduino UNO.

Arduino Code

// Example code to blink an LED connected to pin 13 of the Arduino UNO
// Ensure the HDR-15-24 is providing a stable 5V to the Arduino

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
}

Troubleshooting and FAQs
