Crane Aerospace & Electronics announced a series of enhancements to its popular MTR Series of 30 watt, high reliability dc-dc converters. According to Ed Fuhr, vice president of power solutions, “the MTR Series was enhanced to provide broader compliance to industry standards and in support of more application requirements of its global users.”

“The main improvements,” Fuhr said, “were to expand input voltage range support by 20% to 50V, as well as provide more robust input transient protection, now up to 80V, without otherwise affecting the form, fit or function of the product.” The enhanced MTR Series now meets the overvoltage transient requirements of MIL-STD-704A, DO-160 as well as international standards.

The MTR Series is one of the most widely used high reliability dc-dc converters in aerospace and defense applications. Available in flanged or non-flanged, the MTR Series singles and duals provide up to 30 watts in a small, 2.1 by 1.1 by 0.4 inch (slightly larger for flanged) hermetically sealed case. Fully isolated magnetic feedback, inhibit and synchronization functions and operation over the full military temperature range of -55°C to +125°C ensure reliable performance in demanding environments. The MTR Series are available on defense, land and maritime (DLA) standard microcircuit drawings (SMDs).
