Design with Power Supply Transformer 230 V to 12 V in Cirkit DesignerThe URAQT 200W-12 Power Supply Transformer is a robust and reliable device designed to step down high voltage AC (230 V) to a safer, lower voltage AC (12 V). This transformer is commonly used in electronic circuits to provide a stable power source for low-voltage devices. Its high efficiency and durable construction make it suitable for a wide range of applications, including home appliances, industrial equipment, and DIY electronics projects.
This circuit is a basic AC to DC power supply that steps down 220V AC to a lower voltage using a transformer, rectifies it to DC using a bridge rectifier made of diodes, and smooths the output with an electrolytic capacitor. A rocker switch is used to turn the power supply on and off.

This circuit is designed to convert 240V AC power to both 12V and 24V DC outputs using multiple SMPS units. Terminal blocks are used to organize and distribute the power, while a 120V outlet provides additional AC power access. The circuit is likely used for powering various electronic devices that require different voltage levels.

This circuit converts a 240V AC power source to a 12V DC output using a 12V adapter. The 240V AC power source is connected to a stopkontak, which then supplies the 12V adapter with the necessary AC voltage to produce a 12V DC output.

The transformer has four terminals for input and output connections. The table below describes each terminal:
| Terminal | Label | Description |
|---|---|---|
| 1 | L | Live wire input (230 V AC) |
| 2 | N | Neutral wire input (230 V AC) |
| 3 | 12V~ | 12 V AC output (positive terminal) |
| 4 | 12V~ | 12 V AC output (negative terminal) |
Note: The output terminals (3 and 4) provide an alternating current (AC) voltage of 12 V. Polarity is not fixed for AC outputs.
If you need to power an Arduino UNO, you must first convert the 12 V AC output to 12 V DC using a rectifier circuit. Below is an example of how to connect the transformer to an Arduino UNO:
// Example Arduino code to blink an LED
// Connect an LED to pin 13 with a 220-ohm resistor
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: Ensure the rectified DC voltage is within the Arduino's input voltage range (7-12 V recommended).

Q: Can this transformer be used outdoors?
A: No, the transformer is not weatherproof. Use it in a dry, indoor environment.
Q: Can I use this transformer to power DC devices directly?
A: No, the transformer outputs 12 V AC. You need a rectifier circuit to convert it to DC.
Q: What happens if I connect the output terminals in reverse?
A: Since the output is AC, polarity does not matter. However, ensure proper connections when converting to DC.
Q: Is the transformer compatible with 110 V AC input?
A: No, the transformer is designed for 230 V AC input only. Using 110 V AC will result in reduced output voltage.
