Design with SMPS PSU 12V 10A in Cirkit DesignerThe SMPS PSU 12V 10A is a Switch Mode Power Supply designed to efficiently convert AC mains voltage into a stable DC output of 12 volts with a maximum current capacity of 10 amps. This component is widely used in applications requiring reliable and high-current DC power, such as LED lighting systems, industrial automation, CCTV systems, and powering microcontroller-based projects.
Switch Mode Power Supplies are known for their high efficiency, compact size, and ability to handle varying input voltages, making them ideal for both commercial and hobbyist applications.
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 is designed to provide an uninterruptible power supply (UPS) system with a 12V DC output. It includes a 12V 5A power supply connected to an AC source through a toggle switch, which charges a pair of 18650 Li-ion batteries via a voltage regulator (XL4016). The UPS module ensures a continuous power supply to the load by switching between the power supply and the battery bank.

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.

V+ terminal of the SMPS to the VIN pin of the Arduino UNO.V- terminal of the SMPS to the GND pin of the Arduino UNO.Here is a simple Arduino sketch to blink an LED while powered by the SMPS:
// This sketch blinks an LED connected to pin 13 of the Arduino UNO.
// Ensure the SMPS is properly connected to the Arduino's VIN and GND pins.
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

Q: Can I use this SMPS to power a 5V device?
A: No, the SMPS provides a fixed 12V output. To power a 5V device, use a step-down voltage regulator or DC-DC converter.
Q: Is the SMPS suitable for outdoor use?
A: Most SMPS units are not weatherproof. If outdoor use is required, ensure the SMPS is housed in a waterproof enclosure.
Q: What happens if I exceed the 10A current limit?
A: The SMPS is equipped with overload protection and will shut down or reduce output to prevent damage. Reduce the load to restore normal operation.
Q: Can I use this SMPS to charge a 12V battery?
A: While possible, it is not recommended unless the SMPS has a built-in charging circuit. Use a dedicated battery charger for optimal performance and safety.
