Low-Cost 5V 1A Power Supply for All Your Electronics Projects
Introduction to the 5V 1A Power Supply
The 5V 1A Power Supply is a reliable and cost-effective solution for powering a variety of electronic devices. Whether you’re working with mobile phone chargers, microcontroller power supplies, portable amplifiers, small DC motors, LED light circuits, or Bluetooth/Wi-Fi modules, this power supply is the perfect choice for your project requirements. It delivers a stable 5V output, ensuring efficient performance for all your low-power devices.
How the 5V 1A Power Supply Circuit Works
This simple circuit works by stepping down the AC voltage (from either 220V or 240V) to a low 5V AC using a transformer. The circuit includes four diodes acting as a rectifier, which converts the AC voltage to DC voltage. The resulting DC output makes it ideal for powering devices that require a 5V input supply, such as microcontrollers and small electronics.
Circuit Board Usage and Setup
The circuit board for this power supply features four pins – two input pins and two output pins. Here’s how to use it:
- Input Connections:
- Connect the input pins of the board to a 220V or 240V AC power supply.
- Ensure the wiring is correctly connected to the input supply terminals (green-marked in the image) to avoid any mishaps.
- Output Connections:
- The output terminals are connected to the device you wish to power. The red pin serves as the positive output terminal, while the black pin is the negative output terminal.
- The output can be taken from the capacitor’s end and one leg of the diode.
- Safety:
- Important: Ensure the circuit is powered off when wiring. Do not touch the circuit when it is powered on to avoid electrical shock. To ensure safety, it is advisable to place the circuit in an insulated box.
- Double-check the wiring connections to avoid damage to the circuit.
