SECTION 1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The model TI500 series Static Electrical Power Inverter is a lightweight power converter that translates a
20 to 36 VDC input to a 115 VAC output at 60 Hertz and provides 500 watts (VA) of power. The
alternating current output is defined as a pure sine wave with less than 3% of total harmonic distortion
for clean, noise-free, harmonic-free power to supply nearly any common commercial or consumer load
rated for a nominal input of 115VAC. The TI500 series Inverter, part number MD50-( ), is FAA certified to
TSO C73 and tested to rigorous environmental standards and levels of RTCA DO-160. The small size and
light weight in conjunction with its installation flexibility inside or outside the pressure vessel make it an
ideal choice for aircraft power needs while reducing the challenges associated with other similar products.
Highlighted features include short circuit protection, overload capability, low voltage shut-down,
temperature monitoring, a self-resettable over-temperature disable, and a remote on/off function. The
rugged extrusion that houses the unit is designed to help dissipate heat and provide mechanical strength
against vibration or other possibilities of damage. Two independent fans allow for a smaller unit and
provide a quieter operation while keeping the internal components cool and extending the life of the unit.
