RECOM has introduced an efficient AC/DC power module solution targeting the medium power range of up to 20 W.
The RAC20-SB ultra-compact converter measures 52.4 x 27.2 x 23.5 mm and is supplied in the same housing as the company's 10-Watt model. The device is also pin-compatible with RECOM's 5 Watt model.
The converters are designed for use on universal mains with input voltages of 90 - 264 VAC and are available with output voltages of 3.3 V, 5.0 V, 12 V, 15 V and 24 V. All the models attain a low no load consumption of under 500 mW. 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 percent to 0.6 W/cm3. Efficiency varies according to output voltage limits, reaching a peak of 86 percent at 24 V. In free air convection, the ambient temperature operating range of the converters is between -40 to +70 degrees C. The RAC20-SB family is also fitted with an integrated "Class B" filter. All models are isolated to 3000 VDC minimum and exhibit a MTBF of 250,000 hours to MIL-HDBK-217F specifications.
