Crane Aerospace & Electronics recently rolled out a set of upgrades to its MTR series of 30W high reliability DC-DC converters. The device now features an expanded range up to 50V and input transient protection of up to 80V without affecting the form, fit or function of the product.

The enhanced MTR Series now meets the over-voltage transient requirements of MIL-STD-704A, DO-160 as well as international standards.

The series is used in high reliability applications in aerospace and defence. Available in flanged or non-flanged, the series singles and duals provide up to 30W in a small, 25.4x27.94x10.16mm hermetically sealed case. Fully isolated magnetic feedback, inhibit and synchronisation 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 defence, land and maritime (DLA) standard microcircuit drawings (SMDs).
