Lone Star Aviation's new 12V STEP-UP Converter is the smallest (3" x5" x 2"), most efficient (93-95%) and the most versatile STEP-UP aircraft converter in our industry today. RTCA/DO 160D tested to operate 28V NAC/COM radio equipment such as KX 155, KX 165, KY 196A, KY 196B, and Motorola VHF transceivers on 12V aircraft. Additional 28V electronic devices are HSI, cameras, audio panels, battery backup systems, etc.
Have two of these in two helicopters powering radar altimeters. Since 2009 have never had a unit failure. One ship it powers 28 V LED Nav lighting, even a short in the tail LED wiring did not damage unit. Very impressed.
