Suitable for industrial control, instrumentation and consumer devices requiring stable 5 V supply.

## Long description

MEAN WELL MPM-20-5 is a compact 20 W AC-DC power adapter with a universal input range of 90–264 V and a fixed 5 V DC output rated at 4 A. Encapsulated for protection and designed for PCB through-hole mounting, the unit provides reinforced isolation with two MOPP channels suitable for medical and industrial applications. Its small footprint and low weight make it appropriate for embedded systems, instrumentation and low-power electronic devices that require a reliable, regulated 5 V supply.
Advantages
The adapter delivers a stable 5 V output at up to 4 A with universal AC input compatibility, reducing the need for multiple regional variants. Encapsulation and PCB through-hole format simplify mechanical integration and provide protection against environmental contaminants. Two MOPP isolation barriers enhance safety for systems requiring medical-grade insulation, and the compact dimensions and light weight enable implementation in space-constrained designs.
Suitable for
 Embedded systems and single-board computers requiring stabilized 5 V supply
 Industrial control and instrumentation modules with PCB-mounted power needs
 Medical devices and equipment where reinforced isolation is required
 Consumer electronics and peripherals with low-power DC requirements

How to use
Mount the module onto the circuit board using the specified through-hole footprint and solder the pins according to the manufacturer’s recommended soldering profile. Connect the AC input to the designated input terminals ensuring correct mains wiring and adherence to local safety regulations. Route the 5 V DC output to the load with appropriate decoupling and filtering as recommended for the connected circuitry. Verify proper cooling and avoid obstructing any heat-dissipating surfaces during operation.
Usage recommendations
Use the adapter within its rated input and output specifications and provide adequate PCB clearance and thermal management. For medical or safety-critical applications, follow applicable standards and validation procedures. Add input surge protection and output decoupling as needed to improve transient performance and longevity.
