40W AC/DC power supplies carry medical certification

Recom has extended its range of industrial and medically-approved AC/DC power supplies, with the introduction of the RACM40-K series. The versatile 40W AC/DC power supplies are rated at 40W and supplied in a small 1.6 x 3.0 inch (40.6 x 76mm) footprint for open frame versions and 1.8 x 3.2 inch (45.7 x 81mm) for potted versions.

The RACM40-K series typically achieves 90 per cent efficiency across a wide line and load range. Despite the compact size, the AC/DC power supplies operate up to 60 degrees C at full load and to 85 degrees C with airflow or derating, says Recom. Full load is also available across the line range, 90 to 264V AC.

Single outputs available are 5.0, 12, 15, 18, 24, 36 and 48V, with full protection against short circuit, overload and over-voltage. No-load consumption is below 0.1W at 240V AC.

The RACM40-K series holds 2x MOPP medical certification up to 4000m altitude and is suitable for B (body) and BF (body floating) applications. Additional 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 achieves Class B compliance with a good margin and meets the requirements of medical EMC standard IEC/EN 60601-1-2 4th edition.

Various mounting options are available. The open frame part can be mounted on stand-offs with Molex connectors for input and output and the PCB option has pins for direct PCB mounting. For backwards-compatibility, a 2.0 x 3.0 inch (50 x 75mm) footprint version is available on request. The potted version has additional mechanical fixings for stability.

According to Michael Schrutka, Recom’s AC/DC product manager: “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.”

Samples are available from all authorised distributors or directly from Recom.
