RAC20-SB AC/DC converter

Recom Power Inc. rolls the RAC20-SB 20W AC/DC converter in the medium power range of up to 20W.

This ultracompact converter measures only 52.4mm x 27.2mm x 23.5mm, and is supplied in the same housing as the company's 10W model, and is also pin-compatible with their 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-, 12-, 15- and 24V. All the models attain an unusually low no load consumption of under 500mW. These meet the EU's "green power" policies for 2010, as well as those planned for 2013.

Compared to its predecessor, the power density of the module has been increased by 120 percent to 0.6W/cm3. Efficiency varies according to output voltage limits, reaching a peak of 86 percent at 24V. In free air convection, the ambient temperature operating range of the converters is between -40C to +70C. The RAC20-SB family is also fitted with an integrated "Class B" filter. All models are isolated to 3,000Vdc minimum and exhibit a MTBF of 250,000 hours to MIL-HDBK-217F specifications.
