Emerson Network Power Announces New Triple-Output 45 Watt Power Supplies with Medical and IT Equipment Safety Approvals


Carlsbad, Calif. (11 December, 2012) – Emerson Network Power, a business of Emerson (NYSE:EMR) and the global leader in enabling Business-Critical Continuity™, today announced two new triple-output open-frame ac-dc power supplies, the NPT43-M and the NPT44-M. Extending Emerson’s successful NPT40-M series, these new models are suitable for a wide range of IT equipment, medical, light industrial, instrumentation and process systems, as well as low-power dental and laboratory equipment.

NPT40-M series power supplies are rated for 45 watts power output with convection cooling and up to 55 watts with forced air cooling. The NPT43-M offers 5, 15 and -15Vdc regulated outputs while the NPT44-M offers 5, 12 and 24 Vdc regulated outputs.

The expanded NPT40-M series carries a comprehensive set of worldwide IT equipment (ITE) and non-patient contact and non-patient critical medical safety approvals. These power supplies can accommodate operating temperatures from minus 20 to 50 degrees Celsius at full power and as high as 80 degrees Celsius with de-rating. They feature an industry standard 2 x 4 inch (51 x 102 mm) footprint, and a height of less than 1 inch (25 mm), making them ideal for 1U high portable and rack-mounting equipment.

Emerson Network Power’s NPT40-M series has a wide-range universal input capable of accommodating any ac voltage in the range 90 to 264 Vac. It can also operate from any dc input in the range 127 to 300 Vdc, enabling it to be used virtually anywhere in the world. The NPT42-M power supply requires less than 74 W of input power, and inrush current is less than 50 A peak at 230 Vac input.

Emerson Network Power’s NPT40-M series power supplies fully comply with the international EN 61000-3-2 standard for harmonic emissions. They feature built-in EMI filters (CISPR 22 Class B) and meet rigorous international EMC standards, including FCC Class B, EN 55022 class B and VDE 0878PT3 Class B for conducted noise. Key safety design aspects include fuses in both the line and neutral connections, and a safety-ground leakage current which does not exceed 275 µA. Safety approvals include TUV/UL/CSA 60950 and 60601-1, CB certificate, CE mark (LVD) and CQC mark.

All three outputs on Emerson Network Power’s NPT40-M series power supplies are fully protected against short-circuit conditions. The main output is also protected against overvoltage conditions, and primary-side total power monitoring protects the overall power supply against overload. The power supply delivers a very high demonstrated mean time between failures (MTBF) of 550,000 hours at full load and under 25 degrees Celsius ambient operating conditions.

An optional LPX50 enclosure kit is available for applications that require the power supplies to have maximum component protection.

Emerson Network Power’s NPT40-M series triple-output power supplies are available now.
