  • Enables effective operation over a wide temperature range, with and without forced cooling
  • Comes with protection against sudden current and voltage fluctuations

RECOM has announced the extension of its open-frame AC-DC power supply range with the addition of the RACM60-K Series. The low-profile 5cm x 7cm (2 inches x 3 inches) design features 90 per cent efficiency across its load range and enables full-power operation from -40 degrees Celsius to +55 degrees Celsius without forced cooling, and up to +85 degrees Celsius with derated or forced air. Input range is from 80VAC to 264VAC and outputs available are 5V, 12V, 15V, 24V, 36V and 48V.

The products are suitable for a wide range of applications with EN 62368-1, IEC 61558-1/-2-16 and IEC/EN 60335-1 certifications for ITE/audio-visual, industrial and household use respectively up to 5000m operating altitude.

Providing wide electrical safety

The RACM60-K series features full protection against short-circuits, output over-voltage, over-current and over-temperature and has a line and neutral fusing for medical applications. No-load input current is only 100mW typical at 230VAC.

According to Steve Roberts, Innovations Manager at RECOM, “The high efficiency of these products, right down to 10 per cent load is a major advantage when the application is space-constrained and only convection cooling is available.”

Medical safety and EMC certifications meet ANSI/AAMI/IEC/CSA 60601-1, for 2xMOPP with the isolation of 4kVAC/1 minute suitable for B and BF applications up to 4000m operating altitude. Class B EMC standards are also met in installation class II or class I PELV with grounded output.

Various mounting options are available: Molex connectors for wired installation, wave-solder pins for direct PCB mount with built-in stand-offs and a 5cm x 10cm (2 inches x 4 inches) footprint for legacy design compatibility.
