Emerson Network Power, a business of Emerson and a global
leader in enabling Business-Critical Continuity, has announced the latest
additions to its portfolio of NPS6x-M series 60 W convection cooled open-frame
ac-dc power supplies. The new NPS62-M has a 5 Vdc output and can deliver up to
11 A, while the NPS65-M has a 24 Vdc output and can deliver up to 2.5 A. The
output voltage of each power supply can be adjusted by plus or minus 20
percent.
Emerson Network Power’s latest NPS62-M and NPS65-M power
supplies carry a comprehensive set of worldwide IT equipment (ITE) and non-patient
contact and non-patient critical medical safety approvals. They have a safety
ground leakage current not exceeding 275 µA when operating from their maximum
input voltage. Both models have a compact 2 x 4 inch (51 x 102 mm) footprint
and a height of just 1 inch (26 mm), which makes them ideal for use in light
industrial, instrumentation and process systems, as well as in low-power dental
and laboratory equipment. An optional enclosure kit (LPX50) is available for
maximum protection.
The NPS62-M has a typical full-load efficiency of 80
percent, while the NPS65-M achieves an even higher figure of 87 percent and
meets a variety of rigorous energy efficiency standards, including
International Efficiency Level V and Energy Star 2.0, as well as being California
Energy Commission (CeC) compliant. Both power supplies feature a wide universal
input voltage range of 90 to 264 Vac and are also capable of operating from a
127 to 300 Vdc input. They have a maximum input power requirement of less than
74 W, and a no-load power consumption of less than 300 mW.
NPS62-M and NPS65-M power supplies have a full load
operating temperature range of zero to 50 degrees Celsius, and can be used at
up to 80 degrees Celsius with suitable derating. They both provide tight regulation,
maintaining the output voltage to within plus or minus 2 percent for all
standard line and load conditions, and feature optional remote sense
capabilities to compensate for a 0.5 V drop in the output cables. The power
supplies are comprehensively protected against fault conditions and have a high
demonstrated mean time between failures (MTBF) of more than 550,000 hours.
Emerson Network Power’s NPS62-M and NPS65-M power supplies
feature built-in CISPR 22 Class B EMI filters, and meet the rigorous EN55022
Class B, FCC Class B and VDE0878PT3 Class B conducted noise standards. The
power supplies also comply with the EN61000-3-2 harmonic emissions standard.
International safety approvals include TUV/UL/CSA/NEMKO 60950/60601-1, CE Mark
(LVD) and CB certification.
