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.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e100–240V AC, 50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC ±1%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current\u003c\/td\u003e\n\u003ctd\u003e5A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Rating\u003c\/td\u003e\n\u003ctd\u003e25W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003e5.5mm × 2.1mm barrel plug, centre positive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection\u003c\/td\u003e\n\u003ctd\u003eOver-current, over-voltage, short-circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eA home automation hub using a Raspberry Pi or ESP32, powered reliably for 24\/7 operation.\u003c\/li\u003e\n\u003cli\u003eA desktop LED matrix display driven by an Arduino Mega, drawing up to 5A for vibrant patterns.\u003c\/li\u003e\n\u003cli\u003eA multi-motor robot platform where motor drivers and a controller run off a single 5V rail.\u003c\/li\u003e\n\u003cli\u003eA USB charging station for multiple devices when paired with a step-down module.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery 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.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Raspberry Pi?\u003c\/summary\u003e\u003cp\u003eYes, 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I use this to power multiple devices at once?\u003c\/summary\u003e\u003cp\u003eAbsolutely. 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDoes this PSU come with an AC power cord?\u003c\/summary\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
