  • Battery management
Dual outputs are provided at battery interface for battery operation and -48V backup power input (Battery/backup power -48V common power point: -48VRTN/BAT+, -48V backup power, BAT-). Connect only the battery if there is only 220Vac input and connect the backup power when fed by both 220Vac and backup power. Two diodes are employed for isolation of -48V backup and -48V voltage transferred from 220ac.

Note: There shall be only green LED on for normal power supply form AC input and -48V backup. Other parameters are measured without backup power.

The -54V and 3.4V outputs will be powered by battery under situation of AC mains failure and the normal operation duration under full configuration shall be not less than 4 hours. 
The system is functioned with secondary shutdown, however, the battery load is controlled by main devices. 48V lead acid battery is adopted for backup and the discharge is managed by system. Current limiting shall be conducted during battery charge, the ultimate charge current shall be 1A.
