Emerson Adds New Models to ADN Series Power Supplies

April 27, 2005 by Jeff Shepard

Emerson Network Power, a business of Emerson (St. Louis, MO), announced the addition of new three-phase models to its ADN Series of DIN-rail switching power supplies from Astec Power (Carlsbad, CA). The new models currently offer power ratings of 120 W to 960 W, all with a nominal output voltage of 24 Vdc and a 20 ms holdup time as well as a 50% brownout tolerance from the selected nominal input voltage.

The compact units, intended to mount conveniently on standardized DIN rails in industrial enclosures, are designed for operation in temperatures as high as 60 °C with no derating and no forced-air cooling requirement. Suitable for factory automation and other industrial applications, the ADN Series models can accommodate the large peak loads needed to run motor-controllers and other devices with high surge current demands.

Featuring an industrial-grade design with high mean time between failures and efficiency greater than 90%, the units are approved for use in Class 1, Div 2 hazardous locations and meet the SEMI F47 standard requirements for voltage sag immunity in semiconductor fabrication equipment. All models incorporate power-factor correction and auto select between 340 Vac and 576 Vac nominal input voltages.

The new models feature nominal output-current ranges from 5 A to 40 A, depending upon the power rating, and all can support up to double their rated current for up to 2 sec. The devices sport a user-friendly front panel with adjustable voltage control, parallel operation switch, convenient input/output connections and dc status indicator along with easy mounting hardware on the rear for DIN-rail installation.

Backed by a three-year warranty, the new products meet international safety and performance standards, including listings from UL and CE. Samples are available now with prices starting at $150 for the 120 W model.
