When AC power alive : The "Rdy" is close circuit to active the external Relay . The power supply feeds current into the external loads and charges through Relay to the external battery as well. B. When AC power interrupted : The "Rdy" is remain close circuit to maintain the external Relay remain active, the external battery supply current to the external loads. C. When Battery power low : The "Rdy" become open circuit and the external Relay become inactive to disconnect the battery from external loads. www.chinfa.com 2014.09.09 [email protected] P1 DRA480* SERIES FOR DC BACKUP SYSTEM SPECIFICATION o All Specifications Typical At Nominal Line, Full Load, 25 C Unless Otherwise Noticed GENERAL Characteristics min.
