500W High-Density COTS AC-DC Power

Astrodyne Corporation now offers a high power density COTS ac-dc converter in its Super MegaVerter series. The high-efficiency sMV500 family provides 500W of power. Designed 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 per cubic inch, high typical efficiency in excess of 90% at 230-Vac input and an adjustable output voltage ranging from 60 – 120% of Vo. The unit has output voltage choices of of 12-, 28-, 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 500W, 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 degrees C, can be used in both parallel and series configurations and includes remote sensing and very low output noise.
