Emerson Network Power, a business of Emerson (NYSE:EMR) has introduced a new 350 Watt bulk power supply in a compact package that is ideally suited for product designs using distributed power architecture. The high-efficiency switching power supply from their Astec Power division is the first model in the new high-density 4 x 7 power supply family. The NTS353 weighs in at 8.3 watts per cubic inch and can deliver up to 350 Watts of total power.
Featuring active power factor correction to minimize input harmonic distortion, the Astec Power NTS353 is a compact 85-264 VAC power supply that is ideal for 1U (1.75-inch) rack installations and other low-profile applications. The unit can deliver its full rated output of 350 Watts with 30 CFM forced air or 200 Watts 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. A built-in Or-ing diode eliminates the need for external circuitry when using the unit in a redundant configuration. For maximum versatility, it is also available with a top cover fan designated by a -CF suffix on the model number.
Only 1.50 inches high, the Astec Power NTS350 has a footprint of only 4 inches by 7 inches and can be set up for lengthwise or crosswise airflow, giving designers layout flexibility. 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 Astec Power NTS353 includes a built-in Class B EMI filter, remote sense, remote inhibit and single-wire parallel on the primary output that enables current-sharing to balance loads. It also has an operating temperature range of zero to 50°C without derating and can function up to 70°C by derating the output 2.5 percent per degree C. It complies with IEC EN61000-3-2 harmonic and IEC EN61000-4-X susceptibility standards.
With a demonstrated mean time between failures (MTBF) of over 550,000 hours at full load in 25°C ambient conditions as well as excellent vibration tolerance, the units are designed for long life and trouble-free operation. They also comply with worldwide safety and performance standards from UL, CSA, VDE, NEMKO, AUSTEL, CB and CE.
