A series of medical-grade AC/DC power supplies offer full performance at elevated ambient temperature levels, for example in enclosures where forced cooling is not possible because of hygiene, safety, contamination or acoustic noise. RECOM’s RACM series contains 40, 65 and 100W modules which offer continuous output power with free air convection cooling.

All power supplies are CE marked and 3^rd Edition UL/IEC/EN60601-1 medical certified with 2MOPP/ 250VAC, low leakage (75µA) and BF-rated, trimmable 5-48VDC output voltages.

The RACM series offers an efficiency of up to 93%, low power dissipation and tight regulation over a wide range of output load and input voltage variations. No load power consumption is below 0.3W, ensuring that they conform to the ErP Ecodesign Directive.

The space-saving models are 7.62x5.08cm and are available in open-frame and metal-enclosed designs (100W only available in metal enclosure). The metal-enclosed design is shielded for conducted cooling and operator protection. All models operate from -40 up to 85°C. These Class II power supplies have 4kVAC reinforced isolation between input and output and 1.5kVAC between input/output and EMC ground. All modules comply with EN60601-1-2 Medical EMC, FCC18 and EN55011 Class B EMC standards without external filtering and come with a five year warranty.

These power supplies also conform to IEC60068-2-x for shock and vibration, making them usable for building into portable medical equipment for emergency services, outpatient clinics and home health care. All units are certified for operation up to 5000m altitude without derating, meaning that they can also be used in air ambulances or high-altitude clinics.
