Tiny versatile AC/DC power supplies boast medical certification

09-11-2020 | Recom International | Power

RECOM has expanded its range of industrial and medically-approved AC/DC power supplies rated at 40W in a tiny 1.6” x 3” footprint for open frame versions and 1.8” x 3.2” for potted versions. The RACM40-K series generally attains 90% efficiency over a comprehensive line and load range and notwithstanding the ultra-compact size, works up to 60C at full load and to 85C with airflow or derating. Full load is also obtainable across the line range, 90–264VAC. Single outputs available are 5V, 12V, 15V, 18V, 24V, 36V and 48V, with full protection against short circuit, overload and over-voltage. No-load consumption is below 0.1W at 240VAC.


The series holds 2MOPP medical certification up to 4000m altitude and is appropriate for B and BF applications. Further certifications are IEC/EN 62368-1 for audio-visual/IT, IEC 61558-1 for industrial, IEC/EN 61010 for test and measurement and IEC/EN 60335 for household appliances. In-built EMC filtering accomplishes ‘Class B’ compliance with a good margin and satisfies the requirements of medical EMC standard IEC/EN 60601-1-2 4th edition.


Various mounting options are offered: the open frame part can be mounted on stand-offs with Molex connectors for input and output, or the /PCB option incorporates pins for direct PCB mounting. For backwards-compatibility, a 2” x 3” footprint version is provided on request. The potted version with extra mechanical fixings for stability has inverted pinning compared with the /OF/PCB version.


According to Michael Schrutka, AD/DC product manager at RECOM: “These tiny power supplies are ideal for cost- and space-sensitive applications from industrial, consumer, IT and all the way to patient-connect medical. The high efficiency and standby losses also make them ideal for IoT applications.”
