SYNTHIAM 24 Volt Adjustable Power Supply Instructions

SYNTHIAM 24 Volt Adjustable Power Supply

Product Information

Welcome to this instructional guide on how to create an adjustable 0-24 volt power supply using a PC power supply unit (PSU). This is an improvement over previous tutorials for converting a PC power supply into a bench 12-volt supply. With this adjustable version, you can easily test equipment of various voltages without the need for hunting down an AC adapter and potentially cutting it up only to discover it doesn’t provide the voltage you require.

Adjustable Power Supply
The adjustable power supply is a versatile device that allows you to convert a PC power supply into a bench power supply with a voltage range of 0 to 24 volts. This improvement over previous tutorials makes it easier to test equipment of different voltages without the need for additional adapters.

Step 1

This step is about enhancing the previous tutorial that involved converting a PC power supply to a bench 12-volt supply. The current tutorial will guide you through using the same computer PSU to create an adjustable power supply ranging from 0 to 24 volts.

Materials Needed

1. PC Power Supply
2. Various electronic components (e.g., wires, LEDs, resistors, switch)

Components List

• Two LEDs (1 red, 1 green)
• One switch
• One 200k ohm resistor
• One cement resistor (either 100 ohm J or 120 ohm J; specifics are not critical)
• Eight female connectors
• Two 330 ohm resistors

SpecificationsProduct Usage Instructions

Step 1: Gather Materials
Before starting, make sure you have the following materials:

• PC power supply
• Wire cutters/strippers
• Screwdriver
• Multimeter (for testing)

Step 2: Prepare the Power Supply
Open the PC power supply case using a screwdriver. Take caution and ensure that the power supply is unplugged before proceeding.

Step 3: Locate the Voltage Adjustments
Inside the power supply, you will find a circuit board with various components. Look for the voltage adjustment section, which may consist of potentiometers or resistors.

Step 4: Adjust the Voltage
Using a small screwdriver, carefully adjust the potentiometers or resistors to achieve the desired voltage. Use a multimeter to measure the output voltage and ensure accuracy.

Step 5: Test and Verify
Once you have set the desired voltage, connect the power supply to the device you wish to test. Use a multimeter to verify that the output voltage matches your expectations.

Step 6: Secure and Close
After testing, secure any loose wires and close the power supply case. Ensure that all connections are safe and secure before powering on the device.

FAQ

Can I use any PC power supply for this project?

Yes, most PC power supplies can be used for this project. However, it is recommended to use a power supply with a high wattage rating to ensure sufficient power output.

Can I adjust the voltage while the power supply is connected to a device?

No, it is not recommended to adjust the voltage while the power supply is connected to a device. Always disconnect the power supply before making any adjustments.

How do I know if the power supply is compatible with my device?

Before connecting the power supply to your device, make sure to check the voltage requirements of your device. Ensure that the adjustable voltage range of the power supply covers the required voltage range of your device.

What is the purpose of the adjustable power supply?

The adjustable power supply allows you to test various electronic devices that require different voltages without the need for multiple adapters.

Can I use any PC power supply for this project?

Most standard PC power supplies can be converted following this guide, but the specifications may vary slightly.

Is it safe to modify a PC power supply?

Yes, as long as you follow the instructions carefully and take appropriate safety precautions, such as ensuring the power supply is unplugged and discharged before starting.

Do I need any special tools for this project?

Basic electronic tools such as a soldering iron, wire cutters, and strippers are required.

Instructable – 0 -24 Volt Adjustable Power Supply How To 🙂
Hello guys this is a improment over the past tutorial posted for converting a PC power supply to be a bench 12 volt supply. This tutorial uses the same computer PSU to make a adjustable 0 to 24 volts. This means testing equipment of different voltages will be much easier. Now you don’t need to hunt down a ad adapter and cut it up only to find it’s not really the voltage you needed.
