How many DC Power Centers (DCPC) are there?

Explanation:
DC power distribution in this aircraft relies on redundancy and segmentation to keep critical systems powered. The CRJ-550 uses two DC Power Centers to distribute 28-volt DC power to the aircraft’s DC buses. Having two centers means there are separate paths for power, so if one center is unavailable or isolated, the other can continue feeding the essential loads. In normal operation both centers supply power to their respective sets of buses, and the split helps manage loads and protect circuits with separate circuit-breaker protection. So, there are two DC Power Centers.
