New high power density AC/DC converter for thermally-challenging applications

Astrodyne now offers a new Super MegaVerter Series high power density COTS AC/DC converter, the high-efficiency sMV500 (500W) family. Ideal for use in the most rigorous requirements of mil/aero COTS and other thermally-challenging applications, the 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 90W/in³, high typical AC to DC efficiency in excess of 90% at 230VAC and an adjustable output voltage ranging from 60% to 120% of Vo. The unit has output Vo of 12VDC, 28VDC and 48VDC. The power supply module comes in an industry standard 4.6 x 2.4 x 0.5 inch footprint, has an input range of 85 to 265VAC and a frequency range of 47 to 440Hz. 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 440Hz in a full-brick form factor. Our recent introduction of a 12V model extends the family range and opens new opportunities in military, commercial avionics and other thermally and shock and vibration challenged applications.” The sMV500 features over-temperature, over-voltage as well as over-current and short-circuit protection. The unit has a baseplate operating temperature of -40C to +100C, can be used in both parallel and series configurations and includes remote sensing and low output noise, says the company.
