MEAN WELL IRM-05-12 5W AC/DC gegoten voedingsmodule, 12V 0,42A, PCB-montage, zwart

Embedded systems developers and industrial electronics designers often need a compact, reliable power source that fits directly onto a PCB. The MEAN WELL IRM-05-12 delivers exactly that: a fully encapsulated 5-watt AC/DC module that converts universal mains input (85–264 V AC) into a stable 12 V DC output at up to 0.42 A. Its low-profile black housing and through-hole pins make it ideal for space-constrained applications such as IoT gateways, smart sensors, and automation controllers.

Why choose it

This module eliminates the need for external components—just add input filtering and output capacitance, and you have a complete power solution. Its encapsulated design protects against dust, moisture, and vibration, ensuring long-term reliability in harsh environments. The universal input range means one part can be used in products destined for global markets, simplifying inventory and compliance.

Ideal use cases

• Industrial control boards and PLC auxiliary supplies
• IoT devices and smart home hubs
• Sensor networks and data loggers
• Telecom and networking equipment
• Test and measurement instruments

Good to know

The IRM-05-12 is a Class II device (no earth connection required) and meets EN55032 Class B radiated and conducted emissions without additional filtering in most layouts. It is supplied in a black, flame-retardant plastic case and is compatible with automated wave soldering processes. For higher power needs, consider the IRM-10 or IRM-15 series from MEAN WELL.
