XP 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.
