Applications
The IRM-01-3.3 is used in industrial sensors, smart meters, and building automation controllers that require a compact on-board 3.3 V power supply directly from AC mains without a separate external adapter. Its 1 W output is sufficient for powering microcontrollers, wireless communication modules, and low-power sensors in distributed IoT nodes. Engineers choose this module to simplify PCB design by eliminating discrete AC-DC conversion circuits while meeting safety isolation requirements.

Frequently Asked Questions
What is the output voltage and power rating of the Mean Well IRM-01-3.3?
The IRM-01-3.3 provides a regulated 3.3 V DC output with a maximum output power of 1 W, delivering up to approximately 303 mA of load current. It accepts a universal AC input from 85 VAC to 264 VAC, making it suitable for worldwide deployment without transformer changes or external voltage selection.
In which embedded and IoT applications is the IRM-01-3.3 power module typically used?
This module is commonly used in smart building sensors, energy meters, fire alarm panels, and industrial IoT nodes where a compact, isolated 3.3 V supply must be derived directly from 100–240 VAC mains. The 1 W rating is sufficient for powering 32-bit microcontrollers, low-power wireless radios such as Zigbee or LoRa modules, and analog sensing front-ends.
How does IRM-01-3.3 simplify PCB design compared to a discrete AC-DC conversion approach?
By integrating the full AC-DC conversion chain — including rectification, isolation transformer, switching controller, and output regulation — into a single PCB-mount module, the IRM-01-3.3 eliminates approximately 20–30 discrete components required in a custom design. This reduces PCB area, shortens design time, and simplifies safety certification because the module already carries UL and CE approvals for reinforced isolation up to 3 kVAC.
