High Power Density AC/DC Converter Meets COTS Needs

March 19, 2015
Astrodyne Corporation now offers a high power density COTS AC/DC converter in its Super MegaVerter series.

Astrodyne Corporation offers a high power density COTS AC/DC converter in its Super MegaVerter series.  The high efficiency sMV500 family provides 500 W of power. Ideal for use in the most rigorous requirements of mil/aero COTS and other thermally challenging applications, this new power supply uses an IMS metal baseplate, planar transformers and surface mount construction to produce maximum power density and performance.

The unit features a high power density in excess of 90 W/in³, high typical AC to DC efficiency in excess of 90% at 230 VAC and an adjustable output voltage ranging from 60 - 120% of Vo.  The unit has output Vo of 12 Vdc, 28 Vdc and 48 Vdc.

The power supply module comes in an industry standard 4.6" x 2.4" x 0.5" footprint, has an input range of 85 to 265 VAC and a frequency range of 47 to 440 Hz. Jerrold M. Hornstein, director of business development, mil/aero, Astrodyne-TDI said, "The sMV500 family of products offer an all-in-one 500 W, AC/DC solution with efficiencies in excess of 90%, active PFC and supports AC input frequencies of 47 to 440 Hz in a full brick form factor (4.6"x2.4"x0.5").  Our recent introduction of a 12 V model extends the family range and opens new opportunities in military, commercial avionics and other thermally and shock and vibration challenged applications."

Astrodyne's sMV500 features over temperature, over voltage as well as over current and short circuit protection. The unit has a baseplate operating temperature of -40 to +100 °C, can be used in both parallel and series configurations and includes remote sensing and very low output noise.
