System
The power system accepts alternating current from the commercial utility or a
standby ac power source and rectifies it to produce dc power for the using
equipment. The system’s control and alarm functions interact with the
rectifiers and the office. In addition, the system provides overcurrent
protection and charge, discharge, and distribution facilities. Battery reserve is
connected in parallel and automatically provides a source of dc power if the
commercial or standby ac fails. Battery reserve can be engineered to supply
dc power for a specific period of time. In normal practice, battery capacity is
sized to provide 3 to 8 hours of reserve time.
