5V 5A DC Power Supply | Regulated PSU for Electronics Projects
5V 5A PSU — 25W Regulated Power Supply
The 5V 5A PSU is a compact, regulated switching power supply that delivers a stable 5-volt DC output for prototyping, single-board computers, and high-current applications. With a 5-ampere capacity, it provides ample power for demanding projects while maintaining clean output. Its universal AC input makes it suitable for labs and field use across India.

What You Can Build With This
- A home automation hub using a Raspberry Pi or ESP32, powered reliably for 24/7 operation.
- A desktop LED matrix display driven by an Arduino Mega, drawing up to 5A for vibrant patterns.
- A multi-motor robot platform where motor drivers and a controller run off a single 5V rail.
- A USB charging station for multiple devices when paired with a step-down module.
Compatibility
This supply works with any development board or circuit that accepts a 5V input via a standard 5.5mm barrel jack or screw terminals (adapter may be needed). It is directly compatible with Arduino Uno, Mega, and clones that have a barrel input, as well as Raspberry Pi models when using a micro-USB/Type-C adapter. Ensure your project’s total current draw does not exceed 5A; for modules like high-power LED strips or motors, it provides a clean and steady source.
Wiring Notes
The barrel plug delivers centre-positive voltage; if you cut the connector, the red wire is +5V and black is GND. For bare-wire installations, double-check polarity before powering on. When driving inductive loads such as motors or relays, add a flyback diode across the load to protect the PSU from voltage spikes.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi?
Yes, it works with all Raspberry Pi models. The 5A output easily covers the Pi 4’s peak draw. Use a barrel-to-USB adapter or wire directly to the 5V pins on the GPIO header, taking care to bypass the USB protection circuit.
Can I use this to power multiple devices at once?
Absolutely. You can split the output using a breadboard, terminal block, or custom wiring to run several 5V modules in parallel. The total combined current must not exceed 5A, and it is wise to keep a safe margin to avoid overheating.
Does this PSU come with an AC power cord?
The listing includes the power supply unit only. A standard IEC C13 cable (common “kettle cord”) is required for the AC inlet and is sold separately, though many users already have one from a desktop computer or monitor.
📦 Free Setup Handoff Document Included
