Under normal operating conditions, NPS40-M power supplies require less than 74 W of input power and consume less than 300 milliwatts of power under no-load conditions. They have a high typical full-load efficiency of 87 percent 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 V to 48 V, adjustable by plus or minus 20 percent, NPS40-M power supplies accept a wide universal input voltage range of 90 to 264 Vac (127 to 300 Vdc), enabling them to be used anywhere in the world. The power supplies can operate at full load in temperatures ranging from zero to 50 degrees Celsius and up to 80 degrees Celsius with derating. 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 NPS40-M power supplies feature built-in EMI filters (CISPR 22 Class B) and meet rigorous EN55022-B and FCC part 15 Level B EMC conducted noise standards. Safety approvals include UL/ TUV/CSA/NEMKO 60950/60601-1, CE Mark EMC/LVD certification, CQC Mark and CB certification.
