XP Power launched its AHM Series of 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-W 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. These Energy Efficiency Level V rated units feature efficiency typically 92 percent, 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, according to the company. The power supplies help address 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.
