External Power Supplies Reach 92% Efficiency

Wed, 04/06/2011 - 7:26am
External Power Supplies Reach 92% EfficiencyXP Power launched their AHM series of highly efficient external AC-DC power supplies aimed at a broad range of medical and IT applications. The series comprises five single-output ranges of 85, 100, 150, 180, or 250 Watt output, and provides the popular nominal outputs from +12 to + 48 VDC. All units are convection cooled, removing the need for any internal forced air flow. Not only does this make the units more reliable, but maintains their quiet operation. This being especially important for healthcare equipment sited close to a patient.

These Energy Efficiency Level V rated units are highly efficient, typically 92%, and meet the stringent requirements of global energy efficiency standards both in terms of average power efficiency and less than 0.5 W no-load power consumption. By selecting the AHM series, manufacturers will ensure their products comply with standards such as EISA2007, CEC2008, and the European ErP Directive. In addition, the units meet the internationally recognized safety approval standards for medical equipment IEC/UL/EN/CSA 60601-1 and IT and commercial equipment IEC/UL/EN/CSA 60950-1. They also conform to the medical EMC standard, IEC60601-1-2:2007, meeting level B radiated/conducted emissions to EN55011/22 and the relevant EN61000 immunity standards.
