Carlsbad, Calif.—Emerson Network Power's Astec expanded NTS Series line of 350-watt bulk AC/DC switching power supplies include new 54-volt output configurations for front-end and distributed power applications.
The high-density NTS359 models, in a compact 4-inch by 7-inch footprint, operate at 85 percent efficiency. The convection-cooled configuration provides 200 watts for 1U (1.75-inch high) rack-mount chassis and other low-profile applications, while the fan-cooled option supplies the full rated output up to +50°C with 30 CFM forced air. For added flexibility, the units can be set up for lengthwise or crosswise airflow.
The universal input modules feature active power-factor-correction. A built-in OR-ing diode eliminates the need for external circuitry when using the device in a redundant configuration. The units also include a 12-volt, 1-amp auxiliary output, 5-volt, 2-amp standby output as well as overload, over-voltage, and thermal protection.
The NTS359 models incorporate built-in Class B EMI filtering, remote sense, remote inhibit and single-wire parallelling on the primary output that enables current-sharing to balance loads. The supplies are rated for operation over 0 to +50°C without derating (and up to +70°C, derated at 2.5 percent per °C. They comply with IEC EN61000-3-2 harmonic and IEC EN61000-4-X susceptibility standards.
