Emerson Launches Power Supplies with Medical and IT Equipment Safety Approvals

July 15, 2010 by Jeff Shepard

Emerson Network Power launched the NPS20-M series open-frame power supplies. With a compact 2 by 4 inch footprint and a height of 1 inch, the NPS20-M series supports up to 25W with convection cooling and up to 40W with forced air cooling.

Backed by a comprehensive set of worldwide IT equipment (ITE) and non-patient contact and non-patient critical medical safety approvals, the power supplies are well suited for use in light industrial, instrumentation and process systems, as well as low-power dental, medical and laboratory equipment. The NPS20-M power supplies can operate at full load in temperatures ranging from zero to 50°C (-20°C start up) and, with de-rating, up to 80°C.

Under normal operating conditions, Emerson Network Power’s NPS20-M power supplies require less than 49W of input power and consume less than 300mW of power under no-load conditions. They have an average efficiency of 87% and meet a variety of rigorous efficiency standards, including Energy Star 2.0, California Energy Commission (CeC) and International Efficiency Level V.

Available in five models with outputs ranging from 5 to 48V, NPS20-M power supplies accept a wide universal input voltage range of 90 to 264Vac (127 to 300Vdc). All models have plus or minus 20% user output voltage adjustment and remote sense. They are comprehensively protected against overload and overvoltage conditions and deliver a demonstrated mean time between failures (MTBF) of more than 550,000 hours. An optional enclosure kit (LPX50) is also available to ensure maximum component protection.

All NPS20-M power supplies feature built-in EMI filters (CISPR 22 Class B) and meet rigorous EN55022-B and VDE0878PT3-B conducted noise standards. Safety approvals include UL/ TUV/CSA/NEMKO 60950/60601-1, CE Mark LVD certification, CQC Mark, and CB certification.

Available now, Emerson Network Power’s NPS20-M power supply series is priced starting at $19.00 per unit in production quantities.
