12 Volts DC to 115 Volts AC 400 Hz Three Phase Converter Kit


Above is an example of one customer's finished project. The terminal blocks and fuse were added by the builder.

This complete kit will allow you to use aircraft instruments that require 115 VAC 400 Hz Three Phase power. This includes gyros in attitude indicators (our test unit is a good old J8), directional gyros, airspeed indicators, VSI, etc. There are many high quality inexpensive 400 Hz instruments available via surplus. This power supply will let you operate these from a standard 12 VDC aircraft supply. A completed unit weighs about 10 pounds (transformers are heavy!). Will power several instruments. Includes a PC Board, all components, and instructions.
