Compact AC/DC power supplies

Farnell element14 has launched the RAC48/OF series from Recom, a range of compact AC/DC open frame power supplies with universal AC inputs - from 90 to 265Vac - and fully protected DC outputs that are trimmable to compensate for voltage drops on the output connections.

Typical applications of the RAC48/OF range include industry controls, test and measurement systems and energy-efficient products.

The device operates across a temperature range of -20 to 50°C at full-load and up to 70°C with derating. No-load power consumption is claimed to be less than 0.5W and output voltage accuracy at 24Vdc is said to be ±1%. With a universal input voltage range, the series has a class II power supply and is compact, with a volume of 101.6 x 50.8 x 30mm. The power supplies meet CB, UL, and CE certifications and conform to ErP.
