Low-power external power supplies

4 February 2009 Power Electronics / Power Management

XP Power has announced availability of its AEB series of energy-efficient external AC-DC power supplies aimed at desktop and portable applications. The series, comprising 36, 45 and 70 W models, meet current US and European energy efficiency standards concerning energy-using products. The units are highly efficient, typically more than 85%, resulting in little wasted energy.

The compact units, measuring just 110 x 50 x 20 cm for the AEB36, 36 W model, offer a wide range of single output voltage options. The AEB45 and AEB70 models provide +12, +15, +18, +19, +24 or + 48 V d.c. outputs, while the AEB36 offers +5, +9, +12, +13,5, +15, +18, +24 or +48 V d.c. outputs. There are a total of 20 models within the AEB series.

The power supplies offer an extended operating temperature range, up to +60°C with derating and full power output available at +40°C. The units are compliant with UL 609650-1 and EN60950-1:2001 safety standards and the AEB36 and AEB70 meet the requirements of the China Compulsory Certification (CCC). Most of the models comply with standards for a limited power source (LPS). The power supplies also meet the requirements of EN55022 and FCC part 15 C Level B emission standards for conducted and radiated noise. Output protection features include over-voltage, overload and short circuit.
