5V 4A AC-DC Power Supply Module

Integrate a 5 V DC supply into a properly designed electronics assembly. This AC-DC board provides the power-conversion stage as a module, rather than a finished enclosed plug-in adapter.

✅ Add a dedicated 5 V rail to the build - The module converts its specified input into a 5 V DC output.

✅ Plan around the stated output capacity - The described 4 A, 20 W rating gives the supply stage a defined design reference.

Design the Power Stage as Part of the Assembly

An embedded project needs a supply matched to its voltage and load. This module provides one conversion stage, while the finished product still needs the correct connections, mounting, enclosure and protection around the board.

The input includes hazardous voltages and must be integrated by a qualified person. Check the exact board documentation, isolation requirements and derating before use. Component-level protection functions do not replace safe construction of the finished equipment.
