Compact 60W Power Supplies from Emerson
Convection cooled power supply.
Carlsbad, CA — Emerson Network Power has added to its portfolio of NPS6x-M series 60W convection-cooled open-frame AC-DC power supplies. The new NPS62-M has a 5VDC output and can deliver up to 11A, while the NPS65-M has a 24VDC output and can deliver up to 2.5A. The output voltage of each power supply can be adjusted by ±20 percent.

These 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 275µA when operating from their maximum input voltage. Both models have a compact 2 x 4-in. (51 x 102mm) footprint and a height of just 1-in. (25.4mm), which makes them suitable 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 provide a wide universal input voltage range of 90 to 264VAC and are also capable of operating from a 127 to 300VDC input. They have a maximum input power requirement of less than 74W, and a no-load power consumption of less than 300mW.

NPS62-M and NPS65-M power supplies have a full load operating temperature range of zero to 50°C, and can be used at up to 80°C with suitable derating. They both provide tight regulation, maintaining the output voltage to within ±2 percent for all standard line and load conditions, and have optional remote sense capabilities to compensate for a 0.5V drop in the output cables. The power supplies are comprehensively protected against fault conditions and have a high demonstrated MTBF of more than 550,000 hours.
