RECOM Introduces Ultra Compact 20W AC-DC Power Module

Only months after the launch of the new 4W Class, RECOM introduced the RAC20-SB, described as a highly efficient solution in the medium power range of up to 20W. This ultra-compact converter measures only 52.4 x 27.2 x 23.5mm, and is supplied in the same housing as the popular 10W model and is also pin-compatible with the equally popular 5W model.

The converters are designed for use on universal mains with input voltages of 90 - 264Vac and are available with output voltages of 3.3, 5.0, 12, 15 and 24V. All the models attain an unusually low no load consumption of under 500mW. These not only meet the EU’s "green power" policies for 2010, but also those planned for 2013.

Compared to its predecessor, the power density of the module has been increased by 120% to 0.6W/cm³. Efficiency varies according to output voltage limits, reaching a peak of 86% at 24V. In free air convection, the ambient temperature operating range of the converters is between -40 to +70°C. The RAC20-SB family is also fitted with an integrated "Class B" filter. All models are isolated to 3000Vdc minimum and exhibit a MTBF of 250,000 hours to MIL-HDBK-217F specifications.
