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 2008.03.28 [email protected] FOR DC BACKUP SYSTEM DRAN120 SERIES SPECIFICATION All Specifications Typical At Nominal Line, Full Load, 25oC Unless Otherwise Noticed GENERAL Characteristics Conditions min. typ. max. 3,000 unit VAC Isolation voltage Input / Output Isolation resistance Input / Output, @ 500VDC 100 Ambient temperature Operating at Vi nom -25 Derating Vi nom, from +61 to +71oC Storage temperature Non operational -25 + 85 Relative humidity Vi nom, Io nom 20 95 Dimension Screw terminal type L123.6 x W63.2 x D123.6 Cooling Free air convection Case material Metal M o + 71 C % / oC 2.5 o C % RH mm mm INPUT SPECIFICATIONS Characteristics Conditions min. typ. max. 115 / 230 (auto select) Rated input voltage Io nom Input voltage range Ta min ...
