The TI500 DC-to-AC inverter produces 115 volts at 60 Hz for 500 watts of “wall outlet” power from an aircraft’s 28 VDC input. Lighter and 30% smaller than competing inverters, the TI500 has the same connector and footprint of legacy designs, plus overload and short-circuit protection up to 150% of the rated load.


  • Input transient, overload and short-circuit protection — up to 150% of rated load without damage
  • Remote On/Off
  • Designed and built in Wichita, Kansas, USA
  • Two-year limited warranty
  • Supplies 500 watts of power to multiple cabin accessories, such as laptops, cell phones and MP3 players
  • Compact design — 30% smaller than competing products
  • Lightweight — 3.9 lbs
  • 85 – 90% efficient
