| L-1011 Trainer Installation: 400Hz Power Distribution |
Today we put about 75% of the 400Hz power distribution in place. For the simulator we are really dealing with 3 different power sources: a) the 24V DC power system, b) 120V 60Hz AC power and c) 115V 400Hz AC power. Creating (a) and (b) was easy, however, as you saw in the previous posting, the 400Hz power required a special inverter that converts 60Hz power to 400Hz power. We are actually using the system we built for the 120V 60Hz power to drive the 400Hz power system. In other words, the power sense modules on the 60Hz side instruct bus segments on the 400Hz side to power on and off with respective relays.
To keep things a bit easier to identify we are using blue cables for the 400Hz system. The image below shows the current build state of the 400Hz system.

By the way, the image shows some nifty new DIN rail mounts (the silver rack mounts) that Jim Blasco custom built for the project. They are really awesome and come at quite a cost saving to the project. Thank You Jim! Eventually all the cables will be dressed out once the system is fully built and it will certainly look a lot less like a rats nest :)
