Transformer Rectifier

Also from: TR

Convert electrical AC to DC. A single TR can only supply 3 buses. The APU TR is dedicated to the APU. So if ESS TR fails, TR 1 powers DC 1 bus, DC BAT bus, and DC ESS bus, but if TR 2 fails as well, TR 1 powers DC 1 bus, DC BAT bus, and DC 2 bus.

Failures

If a fault occurs in a TR, it is locked out for the rest of the flight.
