Lone Star Aviation’s FAA TSO approved DC-DC down converter is the first choice among OEMs
and dealers for a high reliability power supply. This third generation converter was designed to
operate as a STEP UP or STEP DOWN power supply. The main converter output is for 28VDC to
13.8VDC to a maximum of 10/12P Amps which operates 13.8 vdc equipment in a 28 volt aircraft.
Additional outputs for the STEP DOWN are 5, 7.5, 9, 13.8, 16, 19, 24, 28 vdc.
The STEP UP is an option and special order for 14 volts to 5, 7.5, 9, 13.8, 16, 19, 24, 28 vdc.
Designed with our latest dc power module operates at 96% efficiency, multiple output voltages and
OV, OC, OT, SC, RP protections. LS03-05001-B was tested under RTCA DO160G
environmental testing.
The connector kit – LS03-05026-1, is required and sold separately.
