Achieves class-B compliance and holds 2MOPP medical certification up to 4000m altitude, making them ideal for IoT applications as well

An improved industrial and medically-approved AC-DC power supply series, the RACM40-K has been introduced that can achieve 90 per cent efficiency across wide line and load range. Despite having an ultra-compact size, it can operate up to 60 degrees Celsius at full load and to 85 degrees Celsius with airflow or derating. Full load is also available across the line range, 90 – 264VAC.

The RACM40-K series holds 2MOPP medical certification up to 4000m altitude and is suitable for B and BF applications. 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. 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.

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.

Various mounting options are available: 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 available. The potted version with additional mechanical fixings for stability has inverted pinning compared with the /OF/PCB version.

“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,” said Michael Schrutka, AC-DC Product Manager at RECOM.

Rated at 40W in a tiny 1.6” x 3” footprint for open frame versions and 1.8” x 3.2” for potted versions, samples are now available from all authorised distributors or directly from RECOM.
