Emerson Debuts NTS353 350W Bulk Power Supply

Emerson Network Power, a business of Emerson (St. Louis, MO), introduced its new NTS353 350W bulk power supply in a compact package that is suitable for product designs using distributed power architecture. The NTS353 is the first model in the new high-density 4 x 7 power supply family. The NTS353 weighs in at 8.3W/in³ and can deliver up to 350W of total power.

Featuring active power-factor correction to minimize input harmonic distortion, the NTS353 is a compact 85Vac to 264Vac power supply that is suitable for 1U (1.75in) rack installations and other low-profile applications. The unit can deliver its full rated output of 350W with 30 CFM forced air, or 200W with convection cooling. The device is also suited for use as an ac-dc front-end for dc-dc converters in a wide variety of applications, including telecommunications, networking, test and measurement, single-board computers, and gigabit Ethernet devices.

Measuring 1.50in high, the NTS350 has a footprint of 4in x 7in and can be set up for lengthwise or crosswise airflow. The device also features a 12V/1A auxiliary output and 5V at 2A standby output as well as overload, over-voltage and thermal protection. The NTS353 has an operating temperature range of 0°C to 50°C without derating and can function up to 70°C by derating the output 2.5%/°C. It complies with IEC EN61000-3-2 harmonic and IEC EN61000-4-X susceptibility standards.

With a demonstrated mean time between failures of over 550,000h at full load in 25°C ambient conditions as well as excellent vibration tolerance, the units also comply with worldwide safety and performance standards from UL, CSA, VDE, NEMKO, AUSTEL, CB and CE. Available now, pricing begins at $299 in OEM quantities.
