| 摘要 |
<p>The invention relates a DC power distribution system, particularly an EMerge® DC power distribution system, comprising a main DC power source (not shown) for providing main DC power, a track (5) connected to the main DC power source for distributing the DC power, an electrical consumer (14) connected to the track for receiving the DC power, and an auxiliary DC power source device (23) for providing auxiliary DC power to the electrical consumer, if the DC voltage level on the track is below a threshold DC voltage level. Thus, if in an emergency situation the DC voltage level on the track falls below the threshold DC voltage level, the auxiliary DC power source device provides auxiliary DC power to the electrical consumer such that it can be still active, for instance, for providing emergency light.</p> |
