Manufactures Part Number: LS03-05003-005, LS03-05003-138, LS03-05003-160, LS03-05003-190 Series Models.
With Lone Star Aviation's NEW ultra Small ( 2.5 x 3.5 inch) dc converter, the installer now has multiple mounting points. Its narrow body shape, mounting brackets, multiple voltages, and FAA-TSO make it the ideal candidate for aircraft and rotorcraft installs.
With more demanding and sophisticated aircraft applications like EFB's systems, cell phone charging, computers, LCD, entertainment sub-systems this dc power supply is a real winner! Available in different models for different voltage requirements, i.e. 24 to 13.8 vdc, 24 to 16.0 vdc, 24 to 19.0 vdc and 24 to 5.0 vdc.
