Open frame AC/DCs offer high efficiency

RECOM adds the RACM60-K series to its range of open-frame AC/DC power supplies. The low-profile 2" x 3" design provides 90% efficiency over its load range, allowing full-power operation from -40C to +55C without forced cooling, and up to +85C with derating or forced air. Input range is a universal 80-264VAC and outputs offered are 5V, 12V, 15V, 24V, 36V and 48V.

The parts are ideal for an extensive 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. Medical safety and EMC certifications meet ANSI/AAMI/IEC/CSA 60601-1 for 2x MOPP with an isolation of4kVAC/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.

The series offers full protection against short-circuits, output over-voltage, over-current and over-temperature and provides line and neutral fusing for medical applications. No-load input current is just 100mW typical at 230VAC.

Various mounting options are offered including Molex connectors for wired installation, wave-solder pins for direct PCB mount with built-in stand-offs and a 2" x 4" footprint for legacy design compatibility. A cover is available for the 2" x 4" option.

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