MEAN WELL IRM-02 Series 3.3V 600mA 2W AC-DC Power Supply Module
MEAN WELL IRM-02 2W AC-DC module: 85VAC to 305VAC input, 3.3VDC output up to 600mA. PCB-mount with overload and short circuit protection.
The MEAN WELL IRM-02 Series 3.3V 600mA 2W AC-DC Power Supply Module converts a universal 85VAC to 305VAC input into a fixed 3.3VDC output of up to 600mA. It is an encapsulated, single-output module designed for powering low-voltage electronics.
Overview
The IRM-02 Series is a compact 2W miniature AC to DC power supply module. Its wide input range allows it to operate across a broad range of mains conditions without the need for external voltage selection, making it suitable for use in various international markets. The module provides a stable, fixed 3.3VDC output at up to 600mA, with a maximum output of 2W. Its PCB-mount design is protected in a resin casing that measures 30 mm (W) x 40 mm (H) x 25 mm (D) and weighs 24.6 g.
Key Features
- Universal input: Operates from 85VAC to 305VAC.
- Fixed output: Provides 3.3VDC at up to 600mA (2W maximum).
- High efficiency: Achieves up to 70% efficiency, minimising heat generation and power loss.
- Low standby consumption: No-load power usage is less than 0.75W.
- Protection: Integrated short circuit, overload and overvoltage protection circuits.
- EMI compliance: Meets EN55032 Class B EMI standards without requiring additional filtering components.
- Built-in filtering: Incorporates EMI filtering components for cleaner power output.
- Cooling: Relies on free air convection, so no fan is required.
- Safety insulation: Features Class II (double) insulation.
Applications
The module suits low-voltage electronics that require a stable 3.3VDC supply, and designs that need a universal 85VAC to 305VAC input. Its compact, encapsulated PCB-mount format makes it straightforward to integrate into space-constrained designs.
