## Description

The TDK-Lambda WMM30CN120-00E is a 30W medical-grade AC/DC external power supply from the WMM30 series, engineered for high-reliability applications in clinical and home healthcare environments. This fixed-output unit provides a regulated 12VDC output at a maximum current of 2.5A. Designed for global versatility, the device accepts a universal input voltage range of 80V AC to 264V AC (47–63Hz) and features a Class II construction, eliminating the requirement for an earth ground connection. The unit is equipped with a standard 2.1mm x 5.5mm x 12mm center-positive barrel connector and utilizes a modular input design, allowing for the attachment of region-specific interchangeable AC plugs (sold separately).

Technically robust, the WMM30CN120-00E meets stringent IEC/ES/EN60601-1 and EN60601-1-11 medical safety standards, featuring 4kV (2xMOPP) input-to-output isolation suitable for B and BF rated equipment. The power supply maintains high efficiency, complying with DoE Level VI and EU Tier 2 energy legislation, with off-load power consumption below 0.075W. Protection features include latching overvoltage protection and hiccup-mode overcurrent protection with auto-recovery. The unit operates within a temperature range of -25°C to +70°C, with linear derating above 40°C, and is housed in a compact 96.7mm x 58mm x 43.25mm enclosure, making it an effective solution for space-constrained medical instrumentation and industrial automation systems.
