How many TRUs are included in the DC electrical system?

Explanation:
Transformer Rectifier Units convert AC power into the 28-volt DC power used by the aircraft’s DC buses. In this DC electrical system, there are four TRUs. This four-unit setup provides sufficient capacity to feed all DC buses while maintaining redundancy, so the loss of one TRU doesn’t leave the DC system powerless—the remaining TRUs can continue supplying power. The battery acts as a backup for essential loads if needed, but the four TRUs are designed to meet normal and fault-tolerant operation without exhausting the backup.
